Hi,

I am using functions from online addons.

Example:

chiplot(S,DEM,A);

This output produces a graph that I cannot edit.

If I add the function code at the end of the usual formatting code, the output gives two plots, one associated with the function and one associated with the formatting code. The plot formtting code does not assimilate into the chi function code and does not change the chi plot (above).

figure('units','normalized','outerposition',[0 0 1 1]);
font_size =32;
hold on
set(0, 'DefaultAxesFontSize', font_size);
% Set the font size for the figure
set(gcf,'color','w');  % shows you what you are using.
set(gca,'linewidth',3, 'fontname','times')  % Set it to times
ZZ = chiplot(S,DEM,A,'mnplot',true,'plot',false)

How can I change the background color or font size on the graph (like I can do with graphs produced by the normal plot function)?

Yes. DEM is a digital elevation model - a GRIDobj (grid object)

S is a STREAMobj

A is flow accumulation (another grid object).

The output 'ZZ'

ZZ = chiplot(S,DEM,A,'mnplot',true,'plot',false)

generates a struct object with lots of variables inside.

I have tried to isolate the variables which produce the graph, export to Excel and plot manually, but I can't find them in the struct object due to how Matlab computes the function.

All I want to do is edit the plot layout. How can I do it?
