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';Change default mail app in OS X
Here is the steps to change default mail app in OS X:
- Open Mail app.
- Select Preferences -> General. Under "Default email reader", select your preferred mail app.
I am running into a problem by following the steps: the default email reader changes back to the original mail app seconds after I made the change. Here is the solution that works for me. Open terminal. Copy and paste the following script.
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -all local,system,userThen try step 1-2 again, and it won't change back again!
