I want to put a variable onto a graph.
I have tried text(x,y,'Text ' num2str(variable) ' moretext') with no luck.
The only information I can find is how to put a variable in the title of a graph. I simply want it to be displayed at a location of my choosing on the graph.

Use the sprintf function:
text(x, y, sprintf('Text %f more text', variable))
NOTE — This is UNTESTED CODE but it should work. Change the format descriptor in sprintf as necessary to provide the result you want.

Ran in:
If you're using a recent release (one that supports string arrays) you can use that.
text(0.5, 0.5, "Text " + pi + " more text")
