Getting the Chart Object

The API library is automatically included in your Logi Info v12+ application when you use Chart Canvas Charts; you do not need to take any special steps to include it in your definition. The first thing you need to do is get the chart object, using this function:

rdGetChartCanvasObject(chartId)

Here's an example that assumes you have a Chart Canvas Chart element with the ID "myChartCanvas1":

var myChartObject = rdGetChartCanvasObject('myChartCanvas1');

With the chart object in hand, you can proceed to manipulate the chart data.
