Line Width on Graph

[karpa]

Hi
I have a Graph Control to plot some lines using PlotLine and Plot Arc i want to change the line width of ALL the plots BEFORE ploting them..
I mean that i want every line i'm plotting on the graph to have a certain line width.. How can i do that..?

Thanks

Check out ATTR_PLOT_THICKNESS.

Yes i've already saw this attribute but in order to use it i must have the plot handle returned (for example) from PlotLine()..
that means, if i understand, that i must plot the line and then change it's width..
i plot thousands of small lines on my graph though and i just want every line i plot to have a specific width..
isn't there a way to to do that for all the lines before i draw them and not after..?

Hi Karpa,

You can disable the ATTR_REFRESH_GRAPH attribute, which will prevent new plots from being drawn. Then, after plotting and then changing the width, you can re-enable ATTR_REFRESH_GRAPH, which should cause the plots to be drawn using the new width.
