    The OutSystems API for plotting charts.

    You can create a chart by dragging a chart widget to the screen. The widget property SourceDataPointList is the list consisting of the DataPoint elements. The DataPoint element defines drawing of the chart: Label, Value, DataSeriesName, Tooltip and Color. You need to provide values to the DataPoint, and in charts with more than one series, you need to specify each series you want to represent in the chart.

    OutSystems uses Highcharts 6.1.0 to generate the charts, and you should consult the Highcharts documentation for implementation and the API.
