DataGraph is fantastic - love it. I'm doing some lovely ternary diagrams but want to colour them to form a nice contour map.
I can colour the graph with a value, and set up the stride to create 9 entries (for instance) but the matched colour only works with 5 entries it seems (which isn't enough)
Does any one know if there a quicker way of generate a colour map with more strides (and more colours) than me automatically going in and adding each one separately? - there is something called clients but i can't find any information on how to use it or what it does.

There is a limited set of predefined color schemes. Is there a particular color scheme that you want to scale up beyond the preset number?

For gradient based schemes like "Purple-Blue" I can interpolate colors to add in more entries.

Beyond 4.2 I am working on continuous color ramps (currently in the beta) and I will use those for the Points command etc. But for now I can add more presets.

I think the two i use are red - blue and white to black (those are the ones i most use in other packages) - but then i do a lot of magnetic materials!

Continuous ramps would be great, but yes if i could just allocate a colour scheme that would work for more than 6 colours using some form of interpolate, that would great.
