[Matplotlib-users] continous colour bar

[Ben E. <bj...@ai...>]

Hi.

I have a set of data with a range of (say) 0 to 100.  Is it possible
to get matplotlib to use the same colour for 0 and 100, so that the
colours "meet" at the ends of the color bar?

One workaround is to just manipulate the data (eg. using abs (x-50)),
but I would rather not, if possible.

Thanks, Ben

The pre-defined hsv colour map has this property - can you use that?
Otherwise, yes, it is possible to define any map you like.
