Colorbar range: maximum not given

Hello,

I have two contourf plots (one plane at z=cte and another at y=cte) that have the same maximum temperature, 65.5ºC. When I "ask" matlab for the colorbar, I see that the maximum temperature on the right colorbar plot (y=cte) does not correspond to the true value.

Any ideas why is this happening and what is the best soluiton?

Thank you in advance.

Best regards, Simão

Notice that the blob is mostly off-screen, either because the data is that way or because the ylimit has been set to not show all of it. It is plausible that in what is shown on the plot, the maximum never reaches the full 65.5.

You can use caxis() to control the maximum that colorbar will use.

After the first plot you could use

first_caxis = caxis();

and then after the second plot you could use

caxis(first_caxis);

before you call colorbar()

Hello Walter Roberson,

Thank you for your answer. In fact, the temperatures are the same as it can be seen in the figures below (maximum temperature is 67.06ºC and not 65.5ºC as said). I still don't undersand why matlab is not giving me the maximum in the colorbar.

After all, your solution works fine for me. Thank you.
