grOverlayChart (Function) In french: grSuperposeGraphe Used to display two different types of charts in the same chart. The two charts are overlaid. Note The first graph must be a column chart (stacked, clustered, etc.), Stock chart (MinMax, candlestick, etc.) or Scatter chart, and the second graph must be a curve.
IF grOverlayChart(GRF_MonHistogramme, GRF_Courbe) = True THEN
Info("Les deux graphes sont superposés")
END
grDraw(GRF_MonHistogramme)
Syntax
<Result> = grOverlayChart(<Destination chart> , <Source chart>)
<Result>: Boolean - True if the charts are overlaid,
- False otherwise. To get more details on the error, use ErrorInfo.
<Destination chart>: Character string Name of the chart that will be used to display the two charts. This chart contains the first chart (Bar chart, Stock chart or Scatter chart). <Source chart>: Character string Name of the chart that will be displayed in the destination chart. This chart must be a Line chart. It will overlay the <Destination chart>. This graph is taken into account as a data source: its title and parameters are not taken into account.. Only the information regarding the legend will be kept.
The link between the two charts is deleted if this parameter corresponds to an empty string ("").
This parameter must correspond to a chart different from <Destination chart> (otherwise, the charts overwrite each other). Remarks - The chart overlay defined by grOverlayChart will be taken into account during the next call to grDraw.
- Warning: The grOverlayChart function does not manage the crosshairs of different superimposed graphs..
