<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.
Remark: This function must be used after <Chart>.Draw (once the chart was 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 (found in the window editor or the 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.
grYCoordinateThe coordinate is calculated on the Y axis.
<Series number>: Integer
  • Number of the affected series.
  • Constant used to find out the coordinates of the point corresponding to the bounds of the axes:
    grAxisXCoordinates of bounds on the X-axis.
    grAxisYCoordinates of bounds on the Y-axis.
<Category number>: Integer
  • Number of the affected category.
  • Constant used to find out the coordinates of the point corresponding to the bounds of the axes:
    grMaxCoordinates of upper bound.
    grMinCoordinates of lower bound.
Business / UI classification: Neutral code
