[NTG-context] Changing the colors of Charts in luametafun

[Jan U. Hasecke]

Hi,

as I'll need to make some business charts in the near future I had a
look into metafun xl.

Here is the first example:

\startMPcode
draw lmt_chart_circle [
samples
= { { 1, 4, 3, 2, 5, 7, 6 } },
percentage = true,
trace
= true,
] ;
\stopMPcode

How can I change the colors used for the sample?
