Stored procedures
Retrieves and/or modifies the value of the line thickness in a Line chart.
Linux Caution: A specific configuration is required to use this function in Linux. For more details, see The charts.
Example
// Chart created through 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>: Control name or character string
Name of the chart to be used. This name corresponds to:
  • the chart name defined through programming with grCreate.
  • the name of Chart control (found in the window editor or in the report editor).
This chart must be a Line chart.
Android Only Chart controls are available.
PHP Only the interactive Chart controls are available.
<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>: Control name or character string
Name of the chart to be used. This name corresponds to:
  • the chart name defined through programming with grCreate.
  • the name of Chart control (found in the window editor or in the report editor).
This chart must be a Line chart.
Android Only Chart controls are available.
PHP Only the interactive Chart controls are available.
<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.

Miscellaneous

  • 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 context menu of the chart).
  • Equivalence: the grLineThickness function is equivalent to the Thickness property.
  • The data defined by grLineThickness will be taken into account during the next call to grDraw.

[ + ] This example presents the different uses of the Chart control.
Different types of charts are presented:
- Pie
- Sunburst
- Line
- Scatter
- Column
- Area
- etc.

The main features presented here are the possibility to customize of charts from the code, as well as to fill the chart from an HFSQL data file, or in the editor.
