ZingChart Build 2.6.0 release notes

Maps Now Have Zooming

Potentially breaking change!

ZingChart now added new ZingChart maps functionality. The new updates include:

- zoom controls
- double click to zoom where cursor is 
- scroll to zoom where cursor is 
- panning 
- zoomTo API Demo
- styling/placement of the zoom controls Demo

In previous versions of ZingChart the maps supported an unconventional and obsolete way of Zooming with x/y coordinates. The new updates allow for zooming, panning and scrolling on maps. We plan to increase the efficiency of this zoom in upcoming releases.

NOTE: The new zooming does not work with bounding-box. This shouldn't be a problem for many, just something that deserves an honorable mention. In this case you should turn off the new zooming functionality.

- turning off new maps zoom functionality Demo

New Features

- ZingChart Maps Zooming Demo
- Stacked bar attributes `%stack-average` and `%stack-length` Demo
- Previously released in v2.5.2 was `%stack-total` Demo
- New svg export functionality. You no longer need just canvas to use `getimagedata` Demo
- Improved Bar Chart rendering speed with `mode:'fast'` coupled with `maxTrackers:0` will increase the render time by over half. Demo
- SVG scatter charts rendering speed were improved. This is the custom code to gain back `tooltips` and `hoverState` Demo
- 3d toolbar has been added back into the build Demo

Updated Features

- TimeZone attribute now supports float values Demo
- plotLabel now supports `rules` and `jsRule`. Great for mapping variables within your `plotLabel.text`Demo
- added extra tokens usable also on node related rules (`%node-x`, `%node-y`, `%node-width`, `%node-height`, `%node-size`)
  - extended parameters passed in the `jsRule` handlers (containing node info: x, y, width, height, size)
  - scaleLabel on `crosshairY` (for value scales), not being bound by nodes, accept the following tokens (%scale-value, %scale-text and %coord) or parameters in `jsRule` (value, text, coord). Coord can be either the x position or the y position, depending on chart type (line vs vline for example)
  - scaleLabel now supports `rules` and `jsRule` Demo
  - `removenode` API method now accepts `nodekeyvalue` as parameter Demo
  - node information now contains selection status for that node
  - added `minMarker` and `maxMarker` objects to allow for different marker styling on **Range** charts Demo
- New Logic for the attribute `exact:true` and displaying crosshair appropriately. 
- 3d chart logic was revamped to allow annotations and cooler depth styling Demo
  - improved 3d layout online,area, reverted display order on z axis, fixed clipping
  - added depth attribute for plot (to be able to force size of the plot band) 
  - added axis object on scales
  - implemented both toggle actions (hide | remove)
  - fixed placement of objects using hook attributes in the 3d space
- added a global object `graph`, positioned at same level as `graphset` which will propagate on all graphs of the graphset. Much like`plot` does to `series` Demo
- Added `object:true` option to `update` API to ease the work with objects. Multiple additions of objects have to be set with `update:false` parameter and after all object additions, `update` API needs to be called.
- Added 'max-values' parameter to `addseriesvalues` to force the chart to remove old nodes when appending new ones Demo

Bug Fixes

- Line chart with `aspect:'spline'` works with `preview` object
- Scale tooltips always displaying 0 index of scale in tooltip
- Chord diagram labels fixed. Original `plotarea` changes in v2.5.0 broke the vertical item labels Demo

Potentially breaking change!

ZingChart now works well with Flexbox. This is a potential breaking change as ZingChart now has some new behaviors related to zingchart.render({height}) attribute.

In previous versions of ZingChart the height would default to 480px if no container height was defined and no height was defined in zingchart.render()

If a user defines zingchart.render({height:100%}) then the default height is no longer 480px. Now, if the container height is 0px it will look like the chart has not rendered because the chart inherited that height.

The easiest way to alleviate this problem is to set a min height on the container element using CSS.

- Added negation : [standard] | currency on scale and plot (along the other formatting attributes) to control how the negative values are displayed independent of the chosen format.
    For example, if on scale format is $%v then the values -100 and 100 will be formatted as:
      negation : "standard" ------- $-100 $100
      negation : "currency" ------- -$100 $100
- JS Formatter: It is now possible to add "format": "javascript:myJavaScriptFunction" to the scale.  When this is done, the JavaScript function will be called for each item on the scale.  It will pass the JavaScript function a single value parameter.  The value returned from the JavaScript function will be displayed in the scale.
- adjust-scale on feed: Added adjust-scale : true | [false] attribute on "refresh" object that will control how the data will be loaded.
    If false (default) the scale interval will stay fixed (and calculated using the max-ticks attribute) as the data is being loaded.
    If true, the scale interval will change as data is being loaded so that the full space of the scale will be used.
- Common Legend across multiple graphs: Added shared : true | [false], group : (numeric) on legend object to allow for shared legends and even grouping the shared legends.
- Wrap title: Title now accepts: wrap-text: true | [false]
  If it is set to true, the text wraps if it is longer than the width of the box.
- Fixed a bug in the ZingChart rules that didn't allow the != operator to always function properly.
          

Features

- Customizing Loading Screen: It is possible to customize the loading progress bar through the zingchart.render method:
        zingchart.render({
                      dataurl: dataUrl,
                      output: 'flash',
                      width: 600,
                      height: 400,
                      container: 'zingchart',
                      preservecontainer: true,
                      liburl: zingLib,
                      progressbar:{
                            color: '#ff0000',
                            text: 'Please Wait',
                            backgroundcolor: '#c3c3c3',
                            bordercolor: '#ff0000',
                            borderwidth: 2,
                            fontcolor: '#ffffff'
                      }
              });
- Inherit scale colors from plot: It is now possible to set "line-color": "inherit" on the scale objects.  If this is set, the scale line color will match the first plot object that uses that scale.
  It is also possible to set inherit on the line-color property of "tick", "minor-tick", and "ref-angle".  If this is set, it will inherit the line-color of the scale.
  Finally, "inherit" can be set on the font-color of "item" and "label".  Once again, it will inherit the line-color of the scale.
- Flash Bootstrap Loader: Zingchart now ships with two swfs.  The first is zingchart.swf which is a small swf that presents the loading screen.  The second is zingchart_lib.swf which is the entire swf.  If you include zingchart.swf, it will present the loading screen to the user and then load the zingchart_lib.swf.
- Zooming has been added to scale-x and scale-y for hbar charts.
- Added "highlight-item" to legend item so that the legend item is highlighted on mousing over the plotnodes.  This is the syntax:
    "legend" : {
        "item":{
            "highlight-item":true
        }
    }
  The effect is a size+1 on the marker and a bold on the text.
- Scale mirroring discrepancies: When scale-y is mirrored in area graphs, the area now correctly flows upward.
- Transparent value for background-color-1 or background-color-2: It is now possible to set background-color-1 or background-color-2 to transparent and have the alpha change.
- Conditional Builds: With a special license, it is now possible to make conditional flash builds including only the features that are needed.  This results in a smaller swf file.
- Legend toggle-action should be inside legend in addition to item: toggle-action can be placed within legend to match with HTML5.
    "legend":{
      "toggle-action":"remove",
      "layout":"float",
      "margin":"10 auto auto auto"
    }
- Gauge now displays properly when scale-r has "mirrored" set to true.
- Changed (with backwards support) the following preview attributes:
    handler -> handle
    handler-left -> handle-left
    handler-right -> handle-right
  Added in handle-left, handle-right, handle-top, and handle-bottom to flash.
- Fixed bug where labels and text were overlapping if the labels font-angle was set to 90 or 270.
- Area3d charts have been given improved graphics to prevent gaps.
- toggle-action: remove now works in bar, bar3d, hbar, hbar3d, pie, pie3d, and nestedpie.
- 3-D Flash Bar chart drawing error: bar3d and hbar3d now match html5
- Legend toggle-action = remove now toggles non-stacked bars appropriately.
- CSV in flash now supports negative and exponential numbers.
- On nested pie charts, the defaults now match HTML5 and small regions are able to trigger tooltips.

                  "background-color":"red",
                  "x":130,
                  "y":130,
                  "width":240,
                  "height":100,
                  "hover-state":{
                      "background-color":"blue"
                  },
                  "label":{
                      "text":"Rect",
                      "background-color":"#fc0 #ff0",
                      "padding":"2 4"
                  },
                  "tooltip":{
                      "text":"My Rectangle",
                      "background-color":"#f00"
                  }
              }
            ]
  - "type" can be set to circle, square, rect, triangle, diamond, plus, cross, star3-star9, gauge3-gauge9, line, poly, or pie.
  - In the case of pie, angle-start and angle-end should be set to indicate the position of the gap.

- Even if zoom is not set for scale-x, the zoom handlers in preview display and zoom is enabled through the preview display. This matches the functionality in HTML5.
- Added watermark object to add your own watermark.
      watermark : {
        url: imageurl
        label:{
          text: "Don't rip me off!" ,

    3.  Set scale guides to solid on all 3d charts
    

Features

- Error bars: New attributes & syntax (per series object or on global plot object):
      error - object, styles the actual error bar, size can be provided either in px or percentage relative to the scale tick size
      errors - array, contains the error values, values can be either numerical or percentage relative to the node value.
    Has multiple formats:
      1. Error is distributed equally on all nodes:
          "errors":[pos,neg]
        Each of the two can be hidden by placing null as value:
          "errors":[null,neg] will show only negative error
          "errors":[pos,null] will show only positive error
      2. Error is specified for every node:
          "errors":[

- New chart type:"range"
    Data should be an array of two values.  The first values will form a line and the second values will form a line and the middle will be filled in.
- Setting min-value:"auto" on scale-y will calculate the scale-y min-value based on the plot points.
- Radar Objects added/modified to bring flash and html5 into alignment.  Notably, the scale-k and scale-v guides now support the item array to rotate background colors and the scale object was added. scale can be used to set size-factor.
- Fixed bug for setting "visible": false on a tooltip at the plot level.

Features

- Feature add [Flash]: Flash has been updated with a "label": {} object in scales that allows the grouping and customization of scale labels. Example:
    "scale-y": {
      "label:{
          "text": "Sample Label",
          "font-size": "14px",
          "font-family": "arial",
          "font-weight": "bold"
      }
    }
- Update:"hook": object added for positioning labels, images and notes relative to datapoints has been added. Syntax as follows:
    "hook": {
        "type": "node",
        "plot":1,
        "index":0,
        "offset-x":25,
        "offset-y":-20
    },
- Feature: Added the ability to rotate text in area markers. "font-angle": 0 will produce horizontal area marker labels.
- Feature: Added a "legend":{} object within the area markers array. Now, "text": as well as font styling parameters may be set within the legend object.
- Feature: Added custom user variables added for Flash and HTML5. User variables may be set using "%data-variable":[] array, where variable may be any specified variable. "%data-variable" may be used as a token in tooltips, value-boxes or the url attribute.
- Syntax update: "max-labels" (Flash) is now aliased to "max-items". "max-items" should be used when specifying how many scale items (including labels, ticks and guides) are desired on a given scale-x or scale-y. Updated as of August 25, 2010.
- Bug Fix: Fixed the color of legend-items to inherit "background-color-1" and "background-color-2" from the series. Previously, "background-color-1" and "line-color" were inherited, causing unintended legend-item colors. As of October 22, 2010.
- Bug Fix: Adding decimals to the "step": in scales without specifying the number of decimals via the "decimals": attribute was previously crashing Flash. This has been resolved.
- Bug Fix: "font-angle": parameter for HTML5 scale labels were not previously working. This has been fixed as of 10 Nov 2010.
- Feature: Upgraded bar charts with many features for bar sizing and overlap. "bar-width", "bars-space-left", "bars-space-right", "bar-space", "bars-overlap" have been added. Values may be set to either pixels or percentages. As of November 10, 2010.
- Bug Fix: The "output" parameter in zingchart.render() has been updated to always allow for render fallback, even if a specific render is chosen. For instance, if output is set to Flash but the chart is accessed via a mobile device not supporting Flash, and HTML5 chart will show (only if proper scripts for HTML5 are included). As of October 15, 2010.
- Feature: Added the ability to set width and height of value-boxes. To do so, set "width" and "height" attributes within "value-box": object. As of August 17, 2010.
- Bug Fix: Value-boxes were showing up below nodes in some line/area charts.
- Bug Fix: Legend-sizing bug fixed for proper handling of different legend-item text length.
- Feature: Added a "curtain":{} object feature for enabling a loading feature when "refresh" is used. Object is placed within "refresh" as follows:
    "refresh": {
        "curtain":{
            "visible": true,
            "background-color":"red",
            "text":"We are Loading!"
        },
        "type" : "feed",
        "interval" : 2,
        "max-ticks" : 10,
        "url" : "fb646-5-feed.php"
    },
- Feature: Added "getimagedata" API call for returning image via API. As of August 18, 2010.
- Bug fix: Previously, when using data as [timestamp,value] pairs, max-value would be ignored/calculated using a default step value. Both min-value and max-value are now recognized as of October 15, 2010.
- Feature added: In Flash, value-box overlap prevention has been added to limit the overlap when showing a large number of slices in pie charts. As of September 3, 2010.
- Bug fix: API calls are now consistent when zooming on a chart. For example, if an item is toggled to 'hide', it will remain hidden upon zooming and interacting with the graph. As of October 15, 2010.
- Feature: Logarithmic scales have been added to HTML5. To set scales to logarithmic, add the "progression": "log" attribute to scale-y. Also added are "exponent": true and "exponent-decimals": 3, to allow for scientific notation. As of October 19, 2010.
- Feature: Added the ability to use multiple scales in Flash and HTML5. Now, "scale-x-n":{} is allowable. To attach a series to a specific scale, set "scales": "scale-x,scale-y-2" formatted string within a specific series object. As of October 15, 2010.
- Feature: Upgraded margin and positioning parameters for ability to set both simultaneously (taking into account height/width of objects). Further information can be found at: http://www.zingchart.com/support/fogbugz/fb953.html?dev=1
- Feature: Added "layout": "float" feature to legend. Used for spacing out legend items evenly within the width of the legend area.
- Feature add: Added the ability to use JavaScript calls via JSON. As of September 7, 2010.
- Bug fix: change syntax from "area-alpha" to "alpha-area" to match HTML5 and Flash (for setting alpha of area chart plot background-colors).
- Feature: "flashvars" no longer needed in Flash for zingchart.render() parameters. Now, Flash and HTML5 both have all of the same zingchart.render parameters. As of August 18, 2010.
- Bug fix: Fixed a bug where scale-x could not be set when using CSV data. As of August 18, 2010.
- Bug Fix: Horizontal bar chart scale labels were rotated the wrong direction by default.
- Bug fix: memory leaks fixed in Flash as of October 15, 2010.
- Default Update: Previously, "type": needed to be set in "value-box" to show any value-boxes in Flash. Defaults have been updated for "type": "all" if the "value-box" object is present. Other values are "none", "max, "min". As of August 18, 2010.
- Syntax Update: "background-repeat" syntax (for use with "background-image") has been updated to reflect CSS styling. As of October 25, 2010, available values are "repeat", "repeat-x", "repeat-y", and "no-repeat".
- Syntax Update: In zingchart.render(), both Flash and HTML5 now recognize 'container' and 'id' for specifying a chart id. 'id' will be the preferred syntax moving forward. As of September 22, 2010.
- Bug Fix: In bullet charts, scale-y was previously being auto sized in relation to the tallest bar height, not taking into account the highest goal value (which caused goal values to not appear. This is fixed as of August 23, 2010.
