Hello,

This is the code i am using to plot a Scatter Plot.

name = Oapp.CreatePage(Oapp.OPT_GRAPH,"Scatter Plot","Graph")
gp = Oapp.GraphPages(name)
gpl = gp.Layers(0)
for i in range(totalColumnsno-1):
gpl.AddPlot(rng[i] , 201)


I have plotted five variables using OriginExt without using pre-defined Templates. But now I am wondering how can I assign different Colors using OriginExt to each Variable during plotting a scatter plot of different variables using RGB scheme and how I can assign different symbols to them. I have tried to assess the colormap but it's not working for me. I would be very thankful if someone can help me with this.


Thank you

Hi,

Various classes in OriginExt implement an Execute method that can execute a LabTalk statement (in string form) in the context of the object (e.g. a GraphLayer).

So you could create LabTalk `set` commands to customize your plots. E.g.:

gpl.Execute('layer.plot=2') # Activate 2nd plot.
gpl.Execute('set %c -c color(255,0,0)') # Set color to red



Here are docs for the set command.
