Display the part of the graph beyond the axis limit in Matlab
When I tried to manually adjust the axis limits of a graph, Matlab will automatically cut off the part of the graph that is beyond the axis limits. This didn't happen before (and before means 2014a or earlier versions). I took a little while to find the cure. Just try the following scripts.
ax = gca;
ax.Clipping = 'off';
