<X>: Optional integer
X-coordinate (in pixels) to be analyzed. This coordinate is expressed in relation to the control.
If this parameter is not specified, the position used in the last call to grInfoXY is taken into account.

Y-coordinate (in pixels) to be analyzed. This coordinate is expressed in relation to the control.
If this parameter is not specified, the position used in the last call to grInfoXY is taken into account.
Remarks

X and Y positions

The <X> and <Y> parameters must be specified at least once.
A WLanguage error occurs if the chart has changed between 2 calls to grInfoXY and if the X and Y positions are not specified.

Column chart

When clicking a bar of the column chart, the area taken into account will be a little bit larger (at the top and at the bottom).

[ + ] Customizing the click on a Pie chart.
Here, the section clicked by the user is pulled out by the application.
To implement this behavior, all you have to do is use grInfoXY (to identify the section clicked) and grPiePullOut (to pull out the section).
WM Click on Chart Cross-platform examples (WINDEV Mobile): WM Click on Chart
[ + ] The "WM Click on Chart" example proposes a solution for pulling out the sections of a Pie chart via a simple click.
This example includes a control template named "TPLC_PullOutChart". This control template is used to pull out the chart sections via a simple click.
To include this feature in another application, all you have to do is import the "TPLC_PullOutChart" template.
