Hi,
I have a couple of questions to ask:
1) do you know if it is possible to set transparency of a symbol in a graph with labtalk?
2) Also, how can I a set the edge size of an empty circle used as a symbol?

Thanks a lot.

You can use Origin C to set Symbol Transparency.
Here is a sample function:

// Set Symbol Transparency
void SetSymbolTransparency(uint uPlot, double dValue)
{
GraphLayer gl = Project.ActiveLayer();
if(gl.IsValid())
{
DataPlot dp = gl.DataPlots(uPlot);
if(dp.IsValid())
{
Tree tr;
tr = dp.GetFormat(FPB_ALL, FOB_ALL, true, true);
tr.Root.Symbol.Transparency.dVal = dValue;
if(0 == dp.UpdateThemeIDs(tr.Root) )
dp.ApplyFormat(tr, true, true);
}
}
}

e.g.
SetSymbolTransparency(0, 66)
will set the symbol transparency of the first plot ( Origin C indexes from 0 ) in the active layer of the active graph to 66%.

Hi,

1. It is right now not possible to set symbol transparency with LabTalk. But we have a plan to implement this in future versions.

2. You could set the "Edge Thickness" by the -kh option switch of set command, for example:


//Set edge thickness of active data plot to 10
set %C -kh 10;
