Syntax

[PowerBuilder]

[Web ActiveX]

Argument

Description

dwcontrol

A reference to the DataWindow control
containing the graph.

graphcontrol

A string whose value is the name of the
graph in the DataWindow control.

seriesname

A string whose value is the name of the
series for which you want to set the line style and width.

linestyle

A value of the LineStyle enumerated datatype
(in PowerBuilder) or an integer (for the Web ActiveX) specifying the
line style.

For a list of values, see LineStyle.

linewidth (optional for
PowerBuilder)

An integer specifying the width of the
line in pixels.

Return Values

Returns 1 if it succeeds and -1 if an error occurs. If any
argument’s value is null, SetSeriesStyle returns
null.

Usage

Data points in a series can have their own style settings.
Settings made with SetDataStyle set the style
of individual data points and override series settings.

The graph stores style information for properties that do
not apply to the current graph type. For example, you can set the
fill pattern in a two–[Unmapped Entity: shy ]
dimensional line graph
or the line style in a bar graph, but that fill pattern or line
style will not be visible.

You can specify the appearance of a series in the graph before
the application draws the graph. To do so:

  • PowerBuilder

    Define a user event for pbm_dwngraphcreate and call SetSeriesStyle
    in the script for that event. The event pbm_dwngraphcreate is
    triggered just before a graph is created in a DataWindow object.

  • Web ActiveX

    Call any of the SetSeriesStyle methods
    in the onGraphCreate event.

Examples

[PowerBuilder]

This statement sets the line style and width for the series named
Costs in the graph gr_product_data in the DataWindow
dw_prod:
