Syntax
grGridlines(<Chart name> , <Displays> , <Axis direction>)
<Chart name>: Character string (with or without quotes)

<Displays>: Boolean
  • True if the grid must be displayed,
  • False otherwise.
<Axis direction>: Integer constant (or combination of constants)
Axis used for the gridlines:
grXCoordinate
(default value)
Marks on X axis (horizontal axis).
grYCoordinateMarks on Y axis (vertical axis).

    • in Column charts (grColumn and grColumnStacked constants), Scatter charts (grScatter constant), Line charts (grLine constant) and Stock charts (grCandleStick, grBarCharts and grMinMax constants) when <Axis direction> corresponds to grXCoordinate.
    • in Scatter charts (grScatter constant), Line charts (grLine constant) and Stock charts (grCandleStick and grBarCharts constants) when <Axis direction> corresponds to grYCoordinate.
  • The gridlines have no effect on Pie charts (grPie constant) and Funnel charts (grFunnel constant).
  • The data defined by grGridlines will be taken into account during the next call to grDraw.
