Stored procedures
Retrieves and/or modifies the value of the line thickness in a Line chart.
Example
// Chart created by programming
// Modifies the line thickness for all the series of the chart
grLineThickness("MyChart", grAllSeries, 4)
// Chart control
// Modifies the line thickness for all the series of the chart
grLineThickness(CHART_MyChart, grAllSeries, 4)
Syntax

Retrieving the thickness of the line (Line chart) Hide the details

<Result> = grLineThickness(<Chart name> , <Series number>)
<Result>: Integer
Line thickness.
<Chart name>: Character string (with quotes)
Name of chart to use. This name corresponds to:
  • the chart name defined by programming with grCreate.
  • the name of the Chart control (found in the window editor or in the report editor).This chart must be a Line chart.
<Series number>: Integer
Number of the series for which the line thickness is requested.

Modifying the thickness of the line (Line chart) Hide the details

grLineThickness(<Chart name> , <Series number> , <New thickness>)
<Chart name>: Character string (with quotes)
Name of chart to use. This name corresponds to:
  • the chart name defined by programming with grCreate.
  • the name of the Chart control (found in the window editor or in the report editor).This chart must be a Line chart.
<Series number>: Integer
  • Number of the series for which the line thickness must be modified.
  • grAllSeries constant to change the thickness of all the series (including the new ones).
<New thickness>: Integer
New thickness of the line. This parameter can correspond to a value greater than 0. The line thickness is set to 1 by default.
Remarks

Units taken into account for the thickness

The line thickness corresponds to values greater than or equal to 0.
  • If the thickness corresponds to 0, the thickness will be 1 pixel on the screen (which means 1 pica when printing).
  • If the thickness is greater than 1, the thickness will be x pixels on the screen, which means x picas when printing.

Various

  • No error is returned if grLineThickness is applied to a chart other than a Line chart. The information is stored and it will be used when the type of the chart is modified (by grType or with the popup menu of the chart).
  • Equivalence: grLineThickness is equivalent to ..Thickness.
  • The data defined by grLineThickness will be taken into account during the next call to grDraw.
