thanks for your advices! 
unfortunately, it doesn't solve my problem.

I dynamically generate a PDF-performance-report for many assets and
portfolios. So adding a gradient manually would be very inconvenient.
The data-connection, calculation and the plot-functions are written in R, so
the PHP solution is not an appropriate solution for me. Thanks anyway!

Everything works fine - it would be just an optical improvement for our

It would be great if anybody has an idea how I can create such a plot
directly in R.


P.S.: I studied "Management Science" at Vienna University of Economics and
Business Administration

I am busy right now, but perhaps this quick help works ;)

* Plot your data with R using the polygone like here (code on this page as
well): http://commons.wikimedia.org/wiki/Image:VaR_graph.png
* save it as a SVG
* add by hand a gradient (
http://de.wikipedia.org/wiki/Gradient_(Grafik) ) eg with Inkscape. I think
that you cannot do this directly with the SVG package.

If you need further help, let me know, perhaps I find some time on the

BTW: Did you study TM in Vienna?
