Methods
ZingChart provides a rich API for controlling chart characteristics from 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.

| Chart ID | String | The id of the chart to target "myid" |
| Method Name | String | The name of the method you are tring to call "addnode" | "getseriesvalues" | etc... |
| Parameters | Object | An object of parameters to pass to the method. The accepted params for this object vary from method to method. Refer to the definitions below for accepted parameters. { plotindex: 2, nodeindex: 3 } |
