MATLAB: When I am plotting contour plot along with colorbar automatically the scale of the z variable and colorbar becomes like 0.23(any value) x 10^4.Why

0.23(any value) x 10^4.caxisclimscale of the z variable and colorbar

How can I stop the scale of the z variable and colorbar from becoming something like 0.23(any value) x 10^4. Why is this happening and how do I stop it? I have tried Clim and caxis without any success!

The only known way to stop it is to set your own axis labels. For example,

zticks = get(gca, 'ztick');
set(gca, 'zticklabel', cellstr(num2str(zticks(:))))

MATLAB: Does the colorbar inaccurately reflect the relationship between colors and function values when CDataMapping is set to direct

The ability for the colorbar to be aware of the axes' CDataMapping property is not available in MATLAB.

To work around this issue, the YTick and YTickLabel properties of the colorbar can be set manually based on the lenght of the colormap. Given a plot generated by the following code:

s = surf(peaks);
set(s,'CDataMapping','direct');
cb = colorbar('location','EastOutside');

The colorbar properties can be modified as follows:

ylimits = get(cb, 'YLim');
set(cb, 'YTick', linspace(ylimits(1), ylimits(2), 9));
set(cb, 'YTickLabel', {'< 0', '8', '16', '24', '32', '40', '48', '56', '> 64'});

MATLAB: Does the colorbar in MATLAB 7.0 (R14) not extend all the way to the extent of the color axis

This bug has been fixed in MATLAB 7.0.4 (R14SP2). For previous releases, read the following for possible workarounds:

There is a bug in MATLAB 7.0 (R14) when using a colorbar on a figure.

To work around this issue, manually set the axis limits to the desired range. For example:

figure;
surf(peaks);
caxis([-10 10]);
cb1 = colorbar;
set(cb1, 'ylim', caxis);
