I recently switched from Matlab 2016b to 2020b and realized that these two versions use different methods to set default y limits of the plots.

In 2016b, Matlab automatically chose the y limit values with nice round figures. e.g., if the data distribution is between 0.49-0.74, it choses [0.4 0.8] as the y limits.

In contrast, 2020b does not seem to care whether the y limits are round figures or not. It uses y limits with obscure values that maximize the visibility of the data points. e.g. [0.46 0.77] in the above example.

I prefer having nice round figures for the y limits. Is there any way to change the way Matlab2020b determines y limits?

Thanks,

Hiroyuki

Hi,

The limits for the axis objects are set automatically in 2020b by default and hence it can take values which are not rounded.

As a possible workaround, you can set the 'YLimMode' property of the axis object to 'manual' to manually set the y-imits to rounded values.

You can go through the following link for further help:

I understand that 2020b automatically sets the y limits, and so did 2016b. My problem is that "the way it sets automatically" is obviously different from the old version. Is there any way I can go back to the old way? Setting the limits manually every time does not sound like a great idea...
