How do you write an underscore in MATLAB legend?

The underscore character ” _ ” is interpreted by MATLAB as a subscript command. The backslash command ” \” is interpreted by MATLAB to indicate that a TeX command is next.

What is a variable subscript?

How does subplot work in MATLAB?

subplot( m , n , p ) divides the current figure into an m -by- n grid and creates axes in the position specified by p . MATLAB® numbers subplot positions by row. The first subplot is the first column of the first row, the second subplot is the second column of the first row, and so on.

You will see updates in your activity feed. You may receive emails, depending on your notification preferences. This is a very basic question, and as my code suggests, it should work, but it’s not: I want have the variables in these legend keys have subscripts, but when MATLAB displays the graph, they appear as written with the underscore symbol.

How to add a subtitle to a plot in MATLAB?

View MATLAB Command. Create a plot, and add a title with the title function. Then create a subtitle containing two lines of text by passing a cell array of character vectors to the subtitle function. Each element in the array is a separate line of text.
