How to Change Marker Size in a .fig MATLAB File?

Hello dear all

I want to know how to change the marker size for a .fig file if that is possible. Note that I only have the .fig file and I don't have access to the X and Y datapoints to use the command scatter(X,Y, 'MarkerSize',10). Is there any way to change the marker size/color by using the command window, or the figure configuration settings?

I appreciate your response in advance

Regards,

Yes, you can use the property inspector.

1. Open the fig file in MATLAB
2. Click on a marker to select them
3. Open the property inspector
4. Expand the Markers section and modify the value in the MarkerSize field.

Thanks Cris

That seems possible and easy, however, I don't know why my Property Inspector window does not have Marker Size !! Do you know why?

[Cris LaPierre]

MarkerSize might not be an editable property. What type of plot is this?

[Benjamin]

This is scatter plot generated by a MATLAB Toolbox (called GPTIPS). I have attached the file, but if changing the marker size is not possible through the file itself, I should find the core files that generates this plot and change it from there.

[Cris LaPierre]

The markers are a property of the Scatter object. For this plot, it is actually listed as "SizeData" in the Color and Size Data section. Click on one of the markers to open the scatter properties.

You can change their size programmatically as well. With this figure set as the current figure, run the following code.

h=findobj(gcf,'Type','scatter')
h.SizeData = 50;

Thank you very much. That works.
