Methods

ZingChart provides a rich API for controlling chart characteristics such as re-rendering a plot (reload), loading new data (setseriesdata), modifying existing charts (modifyplot), zooming in on a data range (zoomto), toggling various interactive features (togglelegend), and much more.

Usage

There is one way to execute methods in ZingChart: the zingchart.exec() method.

.exec

This .exec method will bind and execute a method on your chart. zingchart.exec takes minimum two arguments and a third to pass parameters to the method.

zingchart.exec('myid', 'methodName', {..args})

Color Scale

colorscale.clear
