Hi, quick question on using latex strings for labeling plots in PyPlot.jl: what would be a correct way to do in-place variable substitution? Here’s a piece of code that does not work ….

ax.set_title(L"$ $(a) $")

From the documentation:

If you want to perform string interpolation (inserting the values of other variables into your string), use %$ instead of the plain $ that you would use for interpolation in ordinary Julia strings. For example, if x=3 is a Julia variable, then L"y = %$x" will produce L"y = 3" .

L"y = %$x" will produce L"y = 3"

This is a very nice feature. (It has simplified my LaTeX strings considerably.) Thanks for adding it.

Another option is explicit escaping:

ax.set_title("\$ $(a) \$")

But I agree that using %$ is nicer.
