Hi,

Would it be possible to have a colorbar with two variables (one on each side of the colorbar)?

I.e. if you take this Colorbar for example, I would like to also have different values on the left side of the colorbar for a different variable which shares the same units.

Thank you.

Unfortunately, that is not what I was looking for.

I wanted one colormap with a colorbar with two axes (two variables) where I get to pick the ticks for each of the variables on either side of the colorbar.

Hope that clarifies things?

在 MATLAB Online 中打开

You can add a second tick row on the right side of the colorbar using the code below.

f=figure;
image
c_handle=colorbar;
%c_handle=findobj(get(f,'Children'),'Tag','Colorbar');
new_ax=axes(...
    'Parent',f,...
    'Units',c_handle.Units,'Position',c_handle.Position,...
    'Color','none',...
    'YTick',1:10,'YLim',[1 10],...
    'XTick',[],...
    'TickDir','out');
