How do I draw math formulas programmatically? I want to do on screen what latex does on .pdf.


And I want to draw a math formula in the image generated with ggplotd.

Generate data from those formulas (I like to do this with something like iota(0, 10, 0.05).map!(x => sqrt(x) / (1 + sin(x)^^2)) and then plot that.

For this part ggplotd does have a helper function:

http://blackedder.github.io/ggplotd/ggplotd/stat.html#statFunction

auto gg = statFunction(x => sqrt(x) / (1 +
  sin(x)^^2), 0.0, 10).geomLine().putIn(GGPlotD());

But I assumed he meant adding the formula onto the plot.

Hah, yes, I should have read the question better. Do you support embedding outside images? When I wanted nice mathematical notation generated quickly in D I have used pyd to call matplotlib's builtin math rendering (much quicker than a full latex roundtrip).
