VCS boxfill - cannot set levels

[painter1]

The following demonstrates that you cannot set the levels in a boxfill plot. It works with isofill.
What I would expect to see is a contour legend with colors ranging from 0 to 2, and only half the colors actually used. What I get is a legend with colors ranging from 0 to 1, and all colors used.

import vcs
v=vcs.init()
import numpy
a=numpy.random.random((10,10))
levels=vcs.mkscale(0,2)
levels
[0.0, 0.20000000000000001, 0.40000000000000002, 0.59999999999999998, 0.80000000000000004, 1.0, 1.2, 1.3999999999999999, 1.6000000000000001, 1.8, 2.0]
a.min(),a.max()
(0.013234570510233579, 0.99400848900885075)
gm=vcs.createboxfill()
gm.levels=levels
v.plot(a,gm)

This may be the same as issue 869, but I can't figure out what exactly that issue is.

are you using master? I believe this is fixed in master and you are right this looks the same at #869

@painter1 turns out you need to set the boxfill type in order to turn on levels otherwise by default it uses level_1/2

gm.boxfill_type="custom"
