Origin Version (Select Help-->About Origin): 6.0
Operating System: xP

Hi, im trying to add into an existing script just the part to change the thickness of a scatterplot from 9 to 3, and changing the color of the data plotted through a line plot on layer.Y2 of an arbitrary graph. Is there a command or object referrence that could do these simple things?

Use the set command...

set name -z 3; // set symbol size to 3 points
set name -c 2; // set line & symbol color: 1=black, 2=red, 3=green, etc.
set name -cl 2; // set line color
set name -cse 2; // set symbol edge color
set name -csf 2; // set symbol fill color

name is the name of the dataset you want to change. If the layer has only one curve you can use %C, which always holds the name of the active dataset. Otherwise you can use %(n, @D) to change the nth dataset listed at the bottom of the Data menu.

Not sure what your reference to layer.Y2 means.

Is there a possibility to change the "borderwidth", too? I hope that's the right translation from the german word "Randbreite".

With "borderwidth" I mean the third parameter, You can change in the dataset-box. The other two are size and color. "borderwidth" is normally on standard.

I can't find a LabTalk control for this parameter but you can do it in OriginC. Add the following function to Codebuilder's workspace as described here and call it from LabTalk like this: SetSymbolEdgeWidth value where value varies from 0 to 255 (default).

void SetSymbolEdgeWidth(int borderWidth = 255)
{
GraphLayer gl = Project.ActiveLayer();
if( !gl ) return;
DataPlot dp = gl.DataPlots(-1); // Active curve
dp.Curve.Symbol.EdgeWidth.nVal = borderWidth; // default width = 255
}
