specify axis limit to be nonneagtive

https://www.mathworks.com/help/matlab/creating_plots/change-axis-limits-of-graph.html

discusses controling where data appears in the axes by setting the x-axis, y-axis, and z-axis limits.

Then, how can I set the y axis to be nonnegative (but doe not set the upper limit)?

[alpedhuez]

ylim[0, inf]

You can set the upper limit to Inf to let MATLAB automatically that

axis([0 inf 0 inf 0 inf])

or

xlim([0 inf])
ylim([0 inf])
zlim([0 inf])
