MATLAB: How to make a figure legend multiple lines

Question

The string for my legend is too long to fit into one line. I would like to split it into multiple lines.

Answer 1

To split legend to multiple lines, use the "newline" function or the ASCII character 10 for new line, for example:

>> plot(sin(1:10),'b')
>> hold on
>> plot(cos(1:10),'r')
>> legend({['blue' char(10) 'line'],'red line'})

With MATLAB "strings" you can use the following notation:

>> legend({ "blue" + newline  + "line", 'red line'})

or

>> legend({ strcat("blue", string(newline), "line"), 'red line' })

In addition to the MATLAB command line, the legend can also be updated interactively in the figure itself to include multi-line legend entries.
