New issue 1302: `take_log` works on generic field name, but not front end name https://bitbucket.org/yt_analysis/yt/issues/1302/take_log-works-on-generic-f... Michael Zingale: This script reads in a Castro (boxlib) file and makes two plots. The goal is to not take the log. For the first attempt, we disable log using the field `('boxlib', 'density')`. For the next, we use `('gas', 'density'). Note these are ailased to one another as the print shows: ``` On-Disk Field (boxlib, density): (units: g/cm**3, display_name: '\rho') Alias Field for "('boxlib', 'density')" (gas, density): (units: g/cm**3, display_name: '\rho') ``` but only the one with `gas` successfully disables the log. ``` import yt ds = yt.load("plt00000") print(ds.fields.boxlib.density) print(ds.fields.gas.density) ds.index ds.field_info['boxlib','density'].take_log = False p = yt.SlicePlot(ds,"theta",'density') p.save("densBoxLib.png") ds = yt.load("plt00000") ds.index ds.field_info['gas','density'].take_log = False p = yt.SlicePlot(ds,"theta", 'density') p.save("densGas.png") ``` The test dataset is here: http://bender.astro.sunysb.edu/random/plt00000.tgz (for some reason, I can no longer open the datasets on the yt page, so something changed in the front end that I need to investigate separately, and/or, update the sample datasets)
