ZingChart: 5-April-2017 Release

Build 2.6.0 release notes

click to zoom gif

Potentially breaking change! Maps now have zooming enabled by default.

New Map Updates

- 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.

- 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

ZingChart: 13-October-2016 Release

Build 2.5.0 release notes

Flexbox Updates

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.

Build 2.3.3 release notes

New Features

- Pie Chart / Apple Watch
- Added detached: true attribute.  This allows designated pie slices to start in the detached position and still maintain expected functionality.
- Added additional API “clicknode”.  The used with the existing label_click event will allow developers to fire the clicknode api via the existing label_click event.
- Added ability to set visibility for preview window.
- Implemented full zooming behavior for heatmaps

Updated Features

- Added %node-percent-value (or %npv) token to standalone labels.
- Added “hover-state” object to error bars. This allows users to turn off hover visibility on the error bars, which is especially helpful on bar charts.
- Expanded error bars to work on inverted charts (hbar, vline, varea), in addition to bar, line, area, and scatter.
- “handle” object on preview charts updated to style all four handles simultaneously. (For individual styling, use “handle-left”, “handle-right”, “handle-top”, and “handle-bottom” objects.)
- HOVER STATE stuff:
  - AREA and LINE charts only: “hover-state” is turned off by default. It turns on when the user creates a “hover-state” object. By default, the “alpha” is now set to 1 and the “alpha-area” is set to 0.25. (Markers are styled separately in a “hover-marker” object.)
- Tokens
- Scale tooltips display scale values by default
- Default line width on range charts changed to 2
- Solution for crosshair z sorting with legend.  Implemented new attributes to allow developers to set: “top-layer”:”guide” | “legend”
- Added %scale-value as default text in tooltip if nothing is specified

Bug Fixes

- Fixed issue with drawing scale when a plot was set visible:false on chart load then updated via api.
- Fixed small visual inconsistency in the context menu button.
- Fixed hover issue with bubble charts

5347: Release Notes Ticket

- Added "stepped" aspect on area/area3d charts
- Added "step-start" attribute ([middle] | before | after) on line/line3d and area/area3d charts
- Added "sticky" attribute (boolean) and "timeout" (number) on tooltip to create a time delay before hiding the tooltip. If one hovers over the tooltip within that timeout, the tooltip will stay visible.
- Setting "dynamic" margins on plotarea on xy charts will also modify the plot's dimensions to prevent overlaps between scale label and scale items
- Added "marker-off" attribute on legend to allow different styles for on/off markers
- Added zingchart.bind(sId, sEvent, oFn) and zingchart.unbind(sId, sEvent, oFn) methods for finer event handling management. If sId is null then the event will be assigned to all the existing charts on a page

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

4935: JS Formatter

4947: adjust-scale on feed


adjust-scale : true | [false]

attribute on "refresh" object that will control how the data will be loaded.

borderwidth: 2,
fontcolor: '#ffffff'

1244: Inherit scale colors from plot

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.

4748: 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.
