Hello,

I currently have the saved "fig" file generated by Matlab by using the default histogram "bin" size as I do not know what the histogram plot output would be.

For example:

Histogram_Plot=histogram(Histogram_Inputt_Plot_data);

savefig('Histogram_Plot.fig')

Since I got the saved "Histogram_Plot.fig" file, now I want to redraw the histogram using different bin. How can I extract the data or manupulate from the existing saved fig file and redraw with different bin size now that I got the data from the saved fig file. The reason I want to do this because I do not want to rerun the simulation again and I want use the data I already got from the saved fig file.

Thanks,

Charles

Provided only the histogram is in the figure, the following should work:

hFig = open('Histogram_Plot.fig');
hAxes = hFig.Children;
hHist = hAxes.Children;
hHist.BinEdges = [ <your new bins here> ];

If you have additional lines in the figure (i.e. the figure axes have multiple children), you'll have to ensure you get the correct handle of your histogram.
