MATLAB: I’d like to change the size of the brush marker on a scatterplot.

brush marker sizeMATLAB

I have several scatterplots linked together, everything works and brushes beautifully. However, sometimes the data density is such that I'd like to make the brush marker smaller. I can change the color easily enough, but the size seems immutable.

The ability to change the marker size with brushing does not exist in MATLAB.

The developers are aware of this enhancement, and they might consider this for a future release.

As a workaround, you may try using the Zoom-In and Pan options in the figure, and then use the Brush tool.

You have to dig down a couple of layers to find the data:

h = scatterplot(rand(20,2));
h = get(h,'Children');
h = get(h,'Children');
x = get(h,'xdata');
y = get(h,'ydata');

OK. Good luck to you. Reading the FAQ may help: How_can_I_process_a_sequence_of_files?

Also look up documentation for fprintf() or writetable() to write out the data.
