igZoombar

Issue	Description	Status
igDataChart Radial Series not supported	igZoombar supports only horizontal zooming while Radial Series zooming makes sense only when done on both axes. Because of this, zooming Radial Series with igZoombar does not work properly.
igZoombar thumbnail not rendered when used with igDataChart	igZoombar creates its thumbnail by using the options of the igDataChart control (which is referenced in igZoombar ‘s target option). igZoombar trims off some of these options in an attempt to remove the clutter from the thumbnail. This can make the new option set invalid.
The clone and the target widget of igZoombar doesn’t synchronize automatically	Changing the widget being zoomed by the igZoombar control does not update the clone automatically.
igZoombar does not work with igDataCharts with Stacked Series	The igZoombar creates a clone of the original igDataChart that it targets. By default the igZoombar infers the clone's options from the original chart object (refer to the clone option of the igZoombar). In the case of the stacked series, which have a more complex structure, the original chart modifies the series that the user provides internally. Due to this the igZoombar cannot obtain the original series and cannot recreate the clone automatically.

igZoombar thumbnail not rendered when used with igDataChart

igZoombar creates its thumbnail by using the options of the igDataChart control (which is referenced in igZoombar ‘s target option). igZoombar trims off some of the options attempting to remove the clutter from the thumbnail. This can make the new option set invalid.

Workaround: Use igDataChart options to initialize igZoombar by configuring its clone option.

In JavaScript:

$("#zoombar").igZoombar({
      target: "chart",
      clone: {
            // use igDataChart options
      }
});

The clone and the target widget of igZoombar doesn’t synchronize automatically

Changing the widget being zoomed by the igZoombar control does not update the clone automatically.

Workaround: Using the igZoombar public API, retrieve the element on which the clone is initialized and apply the same changes on it. When updating the igDataChart instance, also update its igZoombar thumbnail clone using the clone API method.

In JavaScript:

$("#dataChart").igDataChart("addItem", {"Item1": "Value1", "Item2": 1000, "Item3": 1019.75}, "series1" );
$("#zoombar").igZoombar("clone").igDataChart("addItem", {"Item1": "Value1", "Item2": 1000, "Item3": 1019.75}, "series1" );

igZoombar does not work with igDataCharts with Stacked Series

The igZoombar creates a clone of the original igDataChart that it targets. By default the igZoombar infers the clone's options from the original chart object (refer to the clone option of the igZoombar). In the case of the stacked series, which have a more complex structure, the original chart modifies the series that the user provides internally. Due to this the igZoombar cannot obtain the original series and cannot recreate the clone automatically.

Workaround:Use igDataChart options to initialize igZoombar by configuring its clone option.

In JavaScript:

$("#zoombar").igZoombar({
      target: "chart",
      clone: {
            // use igDataChart options
      }
});
