Skip points in plotting error bars

Share icon

Hi

I would like to know if there is a simple way to only show error bars every n points, so that the plot is a little less crowded.

Brute force way would be to plot the same wave twice with a mask wave modulo n applied to the one with error bars ?
Here is a macro to do this. The name is a bit misleading...

Macro ReduceErrorBars (sourceName, factor)
    String sourceName
    Prompt sourceName, "Source Wave", popup WaveList("*", ";", "")
    Variable factor=10, n=1, count=1, npoints
    Prompt factor, "Keep every nth point"
 
    npoints=numpnts($sourceName)
    PauseUpdate; Silent 1
 
    Do
        If (count!=n*factor)
            $sourceName[count]=nan
        else
            n+=1
        endif
    count+=1
    while (count<=npoints)
End
