# set_ylog¶

sherpa.astro.ui.set_ylog(plottype='all')

New plots will display a logarithmically-scaled Y axis.

This setting only affects plots created after the call to set_ylog.

Parameters: plottype (optional) – The type of plot that is to use a log-scaled X axis. The options are the same as accepted by plot, together with the ‘all’ option (which is the default setting).

plot()
Create one or more plot types.
set_xlog()
New plots will display a logarithmically-scaled x axis.
set_ylinear()
New plots will display a linear Y axis.

Examples

Use a logarithmic scale for the Y axis of ‘data’ plots:

>>> set_ylog('data')
>>> plot('data', 'arf')


All plots use a logarithmic scale for the Y axis.

>>> set_ylog()
>>> plot_fit()
