how to change the sequence of the legend

问题

I want to change the sequence of the legend.

See the figure. I want the sequence to be: green and data2, blue and data3, black and data4, red and data1.

Could anyone give a demo?

回答1:

Change the order in which the plots are added to the figure, and then call legend normally. That should do it.

You can also do it as follows. First get handles to the individual plots:

h1 = plot(1:5);
hold on
h2 = plot(11:15, 'r');

Then call legend specifying the order:

legend([h1 h2],'plot1','plot2')

or

legend([h2 h1],'plot2','plot1')

回答2:

In case, you have already made the plots or if you added some plot at the end, which want to reorder to somewhere in middle, you can try this way:

1) Go to show Plot Tools and Dock Figure.

2) Delete the data (which you want to move to bottom). Then undo delete.

3) Refresh legend.
