How to get handle of corrplot?

Hello

I'm using corrplot for creating a correlation plot of my data. This works fine but I have two problems with it:

1. How can I get a handle of the figure so that I can change the figure size (full screen) and changing the font sizes? h = corrplot(...) and also gca does not work.

2. The diagonal represents the histograms. Unfortunately, my data has a pretty large tail, that means there are some few data points far right on the x-axis. That's why this histograms on the diagonal shows mostly nothing. So I think I have to decrease the x-axis limit for the histograms. How can I do this in corrplot?

Since corrplot does not return any figure handle you'll have to acquire it with gcf. Make sure that the correct figure is selected first.

hfig = gcf;
haxes = findobj(hfig, 'Type', 'Axes');
arrayfun(@(ax) xlim(ax, [your limits]), haxes); %to change all the axes limit

Thanks for your answer. But when I call

hfig = gcf;  
set(hfig ,'Name', 'Correlations', 'NumberTitle', 'off', 'units', 'normalized', 'outerposition', [0 0 1920 1080]);
  set(hfig , 'Units', 'centimeters');
  set(hfig , 'FontSize', 22, 'fontname', 'times');
  xlhand = get(hfig ,'xlabel');
  set(xlhand,'Interpreter','latex', 'fontsize', 24);
  ylhand = get(hfig ,'ylabel');
  set(ylhand,'Interpreter','latex', 'fontsize', 24);

Nothing happens. Why?

I have managed to get it work:

hfig = gcf;
haxes = findobj(hfig, 'Type', 'Axes');
arrayfun(@(ax) xlim(ax, [your limits]), haxes); %to change all the axes limit
set(hfig ,'Name', 'Correlation Matrix', 'NumberTitle', 'off', 'units', 'normalized', 'outerposition', [0 0 1920 1080]);
set(hfig , 'Units', 'centimeters');
set(haxes , 'FontSize', 22, 'fontname', 'times');

There are only three last problems.

How can I also increase the size of the correlation numbers? I mean the number in each box.

How can I set different x-axis limits for each block (each column)?

How can I set different font sizes for the labels of the axis and the numbers (ticks) of the axis?

A better way to get the axis handles in corrplot() is by using the 3rd output which is a matrix of plot object handles.

[~, ~, h] = corrplot(data); 
haxes  = [h.Parent];

Hi Sepp,

To modify the size of the correlation numbers, do the following:

hfig = gcf;
textboxparent=findall(hfig,'Tag','scribeOverlay');
textboxchildren = get(textboxparent,'Children');

for hh=1:size(textboxchildren,1)
    textboxchildren(hh).FontSize=16;
end
