Synopsis
Return the data used by plot_ratio.
Syntax
get_ratio_plot(id=None, recalc=True)
Examples
Example 1
Return the ratio of the data to the model for the default data set:
>>> rplot = get_ratio_plot() >>> np.min(rplot.y) 0.6320905073750186 >>> np.max(rplot.y) 1.5170172177000447
Example 2
Display the contents of the ratio plot for data set 2:
>>> print(get_ratio_plot(2))
Example 3
Overplot the ratio plot from the 'core' data set on the 'jet' data set:
>>> r1 = get_ratio_plot('jet')
>>> r2 = get_ratio_plot('core')
>>> r1.plot()
>>> r2.overplot()PARAMETERS
The parameters for this function are:
| Parameter | Type information | Definition |
|---|---|---|
| id | int, str, or None, optional | The data set. If not given then the default identifier is used, as returned by `get_default_id` . |
| recalc | bool, optional | If False then the results from the last call to `plot_ratio` (or `get_ratio_plot` ) are returned, otherwise the data is re-generated. |
