The issue is that once the "Position" property of the colorbar is manually set, the axes start to ignore the colorbar and will no longer automatically resize to accommodate the colorbar. Unfortunately, the "InnerPosition" property of UIAxes cannot be manually changed prior to R2020b.
Below are two workarounds. Both of them require using regular axes instead of UIAxes:
1. Use regular axes instead of UIAxes and manually adjust the position of axes and colorbar.
Unlike the "InnerPosition" property of UIAxes, we can set the "Position" property of regular axes. In this workaround, we manually set the value of the "Position" property of the colorbar and regular axes. The example code is as below:
%create the figure fig = uifigure; %create the regular axes , set the NextPlot to replacechildren ax = axes(fig, 'NextPlot', 'replacechildren'); %load image, we use peppers.png as an example img = imshow('peppers.png', 'parent', ax); %create colorbar cb = colorbar(ax); %manually change the position of colorbar to what you want cb.Position = [0.8838 0.1600 0.0400 0.7000] %manually change the position of the image by changing the position of the regular axes ax.Position = [0.1255 0.1349 0.6 0.8050];
After modifying the Position values of axes and colorbar, the value will remain the same when you load in a new image.
2. Use regular axes instead of UIAxes and put the axes into a tile chart layout
This workaround is to put the axes into a "tiledlayout", which creates a tiled chart layout to display plots in the current figure. This will automatically keep the colorbar outside of the image with a fixed position and automatically adjust the size of the image. The example code is as below:
%create the figure fig = uifigure; %set the tiled layout t = tiledlayout(fig,'flow'); %create the regular axes ax = axes(t, 'NextPlot', 'replacechildren'); %create colorbar cb = colorbar(ax); %load your image, we use peppers.png as an example img = imshow('peppers.png', 'parent', ax);
