Hi,
I have a plot, and when I manually select a data point and then export the cursor data to workspace, I can see and export the coordinates and the data index (which I assume is useful to know the order of data points).
But when i use the brush tool to select multiple data points, I can only see and copy the coordinates, but not the data index.
How can I get the data index using the brush tool?

Hi,
You can refer to the MATLAB answer below which discusses about obtaining the brushed data index from a plot.

This error comes up:
Unrecognised function or variable 'pos'
