Drawing graphs from Mata

[Niels Henrik Bruun]

Hi
Is there a way to build graphs directly from Mata.
I mean without first moving graph data into Stata.
An example could be making a scatter plot based on 2 vectors or 2 columns/rows in a matrix.
Or a boxplot from a vector.

I've been using -svmat- to get graph data from a matrix into the used dataset of Stata after saving the current dataset by either -preserve- or -tempfile-.
This I did with matrix data in Stata, but I'm going to use Mata more and more and came to wonder whether there is a more direct way.

Looking forward to hear your suggestions.

Although it isn't an answer, I'd also be interested in this and/or ways that the graphics engine in Stata could be modified to avoid turning to other platforms for creating graphs.

In particular to be able to use transparency (alpha blending). For some wishfull examples, see:

mm_plot() from the moremata package would be a solution, although in reality it is Stata which does the job.
