<Chart>.PointInfo (Function)

In french: <Graphe>.InfoPoint

Returns the screen coordinates of a point or the screen coordinates of a value found in a chart.

This function allows you to retrieve the coordinates of a chart area in order to draw in this area with the drawing functions.

Note: This function must be used after function <Chart>.Draw (when the graph has been drawn).

Example

// Coordinates of the center of a Radar chart displayed in a Chart control
Coordinates is string
Coordinates = CHART_Radar.PointInfo(grXCoordinate, grAxisX, grMin) + "," + 
		CHART_Radar.PointInfo(grYCoordinate, grAxisY, grMin)

// Coordinates of the useful area of a chart displayed in a Chart control
Useful_Area is string
Useful_Area = CHART_Lines.PointInfo(grXCoordinate, grAxisX, grMin) + "," + ...
		CHART_Lines.PointInfo(grXCoordinate, grAxisX, grMax) + ":" + ...
		CHART_Lines.PointInfo(grYCoordinate, grAxisY, grMin) + ","+ ...
		CHART_Lines.PointInfo(grYCoordinate, grAxisY, grMax)

// Coordinates of the area included between the minimum and maximum Y-coordinate
Area is string
Area = CHART_Lines.PointInfo(grYCoordinate, 1, grMin) + "," + ...
		CHART_Lines.PointInfo(grYCoordinate, 1, grMax)

Syntax

<Result> = <Chart control>.PointInfo(<Type of axis> , <Series number> , <Category number>)

<Result>: Integer

Coordinates of the specified point (in pixels) according to the specified axis. The coordinates are specified in relation to the chart (and not in relation to the screen).

<Chart control>: Control name

Name of the Chart control to use (in the window or page editor).

<Type of axis>: Integer constant

Type of the axis taken into account when calculating the coordinates:
grXCoordinate
(Default value) The coordinate is calculated on the X-axis.
grYCoordinate The coordinate is calculated on the Y-axis.

<Series number>: Integer

Number of the affected series.
Constant used to determine the coordinates of the point corresponding to the axis boundaries:
grAxisX Coordinates of bounds on the X-axis.
grAxisY Coordinates of bounds on the Y-axis.

<Category number>: Integer

Number of the affected category.
Constant used to determine the coordinates of the point corresponding to the axis boundaries:
grMax Coordinates of upper bound.
grMin Coordinates of lower bound.
