Multiple Scattergram plots in the same figure

I would like to create two scattergram plots (Wavelet toolbox) in the same figure. I tried using the subplot command but it did not work (no error message, but only plotted the 2nd figure, not in subplot position).

scattergram(wf,Sgood,'FilterBank',vizLevel); title(good);

The easy way

Create two different figure; then copy the axis of the second figure to the first figure and change the axis positions; then delete the second figure.

% Create first figure
fh(1) = figure();
scattergram(...);
axh(1) = gca;

% Create second figure
fh(2) = figure();
scattergram(...);
axh(2) = gca;

% Change position of 1st axis
axh(1).Position = [.07,.35,.35,.44];
% Copy axis #2 to figure 1
axh(2) = copyobj(axh(2),fh(1));
% Change position of new axis 
axh(2).Position = [.55,.35,.35,.44];
% Delete second figure
delete(fh(2))

The hard way

If you look at the function in waveletScattering.m > scattergram(), it has an optional output that is the scattergram. When that output is included, the figure is not drawn. You can use that output to plot the figure in any axis you want but it comes at the cost of doing additional work that is done within the function.

The lines that create the plot are below.

if isVector
    plot(AX,tstamps,cfs); grid on;
    axis tight; 
else
    surf(AX,tstamps,F,cfs); view(0,90);
    shading interp; axis tight;
end

You'll need to step through that function in debug mode to re-create the tstamps (and F) values. "cfs" is created by including the output to the scattergram function.

csf = scattergram(...);

This worked for me but I needed to be in Matlab R2019A... R2017A did not like the syntax of this command:

axh(1) = gca;

Glad it worked!

The gca() command has been around since prior to 2006.

scattergram(), however, joined the club in r2018b so that line was probably the dealbreaker for you in r2017a.
