Syntax
<Result> = grOverlayChart(<Destination chart> , <Source chart>)
<Result>: Boolean
  • True if the charts are overlaid,
  • False otherwise. To find out the error details, use ErrorInfo.
<Destination chart>: Character string (with or without quotes)
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 (with quotes)
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 chart will be taken into account as data source: its title and its parameters will be ignored. 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).
