grPointInfo (Function) In french: grInfoPoint
 Warning
From version 24, grInfoPoint is kept for backward compatibility. This function has been replaced with grPointInfo.
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 grDraw (once the chart was drawn).
x is int
x = grPointInfo("MyChart", grXCoordinate, 1, 1)
Coordinates is string
Coordinates = grPointInfo(CHART_Radar, grXCoordinate, grAxisX, grMin) + ", " +
grPointInfo(CHART_Radar, grYCoordinate, grAxisY, grMin)
Useful_Area is string
Useful_Area = grPointInfo(CHART_Lines, grXCoordinate, grAxisX, grMin) + ", " + ...
grPointInfo(CHART_Lines, grXCoordinate, grAxisX, grMax) + ":" + ...
grPointInfo(CHART_Lines, grYCoordinate, grAxisY, grMin) + ", "+ ...
grPointInfo(CHART_Lines, grYCoordinate, grAxisY, grMax)
Area is string
Area = grPointInfo(CHART_Lines, grYCoordinate, 1, grMin) + "," + ...
grPointInfo(CHART_Lines, grYCoordinate, 1, grMax)
Syntax
<Result> = grPointInfo(<Chart name> , <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 name>: Control name or character string Name of the chart to be used. This name corresponds to:- the name of the chart defined programmatically with grCreate.
- the name of the Chart control (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 find out the coordinates of the point corresponding to the bounds of the axes:
| | | 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 find out the coordinates of the point corresponding to the bounds of the axes:
| | | grMax | Coordinates of upper bound. | | grMin | Coordinates of lower bound. |
