Re: [yt-users] accessing colorbar directly

Hi Nathan, thanks, it worked exactly in the way I meant! Just for your information: my problem was to customize a slice of GridLevel, in such a way to have the word "AMR level" on the colorbar, and to have integer values for the ticks. Using your suggestion, I did that in the following way (pf and c given elsewhere in my script): sll = SlicePlot(pf, 'x', "GridLevel", c, width = (8.0, 'mpccm')) sll.set_log("GridLevel", False) sll.set_zlim("GridLevel", 0.0,8.0) colorbar = sll.plots['GridLevel'].cb colorbar.set_label("AMR level") colorbar.set_ticks([1.0,3.0,5.0,7.0]) colorbar.set_ticklabels([1,3,5,7]) sll.save() Cheers, Luigi On Wednesday 25 September 2013, Nathan Goldbaum wrote:

Hi Luigi,

You can access the colobar and colorbar axes like so:

slc = SlicePlot(pf, 'x', 'Density') plot = slc.plots['Density'] colorbar = plot.cb colorbar_axes = plot.cax

Take a look at this notebook for an example: http://nbviewer.ipython.org/url/hub.yt-project.org/notebooks/8bc973e0da2d46 97a8e1d5a7a203d19d.ipynb

Let us know if you have any trouble getting this working for your use case.

Dear all,

I am in the process of moving most of my visualisation scripts from PlotCollection to the PlotWindow interface. One feature that now I am not able to find is the capability of customising the tick values in the colorbar of a plot. Inspired by the example script found in

http://yt-project.org/docs/2.5/cookbook/simple_plots.html#accessing-and-m odifying-plots-directly,

I was thinking about interacting with a matplotlib object directly, but I am not able to find a suitable one. Could you please suggest me a workaround for this issue? Thanks in advance,

Luigi
