I'm trying to create both glyphs and contours using fixed colors for groups
of concentrations:
0-59 = green
60-84 = yellow
85-109 = orange
110 and above = red
How would I tell OpenDX to either categorize my data in such a way so that
values within the individual ranges would be assigned the right color, or
is there a way to feed a listing of ranges into either colormap or
autocolor to place all my data points in the appropriate bin?
Thank you,
Michael Rizzo
Send a List of the data values to Construct "origin" and a List of
the RGB values (as 3-vectors of course) to the same Construct "data"
then feed the output of Construct to Colormap "colormap" input. Do
not otherwise data-drive the Colormap. After you've connected
Colormap to Color etc. and executed once, you can open the Colormap
editor to see the curves you've constructed. If they aren't right,
edit the Lists and try again.
You can (as I have done) also create a 'spreadsheet' file of 4
columns (data, R, G, B) ImportSpreadsheet and build the colormap
field from those columns and a Construct. This may make it easier to
maintain or feed in a different color scheme.
