I would like to color contours represented as vector lines according to
their height represented as z coordinate.

d.vect zcolor= ?

I forgot to mention. This works for me with points but not with lines.
Actually, it is what manual says:

zcolor=style
Colorize point or area features according to z-coordinate

What about d.vect.thematic?? Have you tried it?

From the manual:

“d.vect.thematic creates thematic maps from vectors of all types and numeric attributes (stored in the data table connected to a vector map). Thematic maps can be displayed by either a graduated color scheme (for all vector types), as graduated icon sizes (for point and centroid types), or graduated line widths (for lines and boundaries with associated attributes). The user selects the vector map to be mapped and attribute column from which to derive mapping intervals, and (optionally) the layer for attribute data.”

Best,
Vero

Hi Veronica, actually I did not but I see that it is not available in GUI
and it is also broken in general. I would have have to fix it first which
I'm not going to do right now :wink: But the module options looks promising.

From the manual:

"d.vect.thematic creates thematic maps from vectors of all types and
numeric attributes (stored in the data table connected to a vector map).

yeah, it seems it’s broken :frowning:
I used it quite some time ago for ploting graduated points… options are indeed very nice!
Hope someone fix it :slight_smile:

best,
Vero
