Synopsis
Return the preferences for plot_data.
Syntax
get_data_plot_prefs(id=None) id - int or str, optional
Description
The plot preferences may depend on the data set, so it is now an optional argument.
Example
After these commands, any data plot will use a green symbol and not display Y error bars.
>>> prefs = get_data_plot_prefs() >>> prefs['color'] = 'green' >>> prefs['yerrorbars'] = False
PARAMETERS
The parameter for this function is:
Parameter | Definition |
---|---|
id | The data set that provides the data. If not given then the default identifier is used, as returned by `get_default_id` . |
Return value
The return value from this function is:
prefs -- Changing the values of this dictionary will change any new data plots. This dictionary will be empty if no plot backend is available.
Notes
The meaning of the fields depend on the chosen plot backend. A value of none means to use the default value for that attribute, unless indicated otherwise. These preferences are used by the following commands: `plot_data` , `plot_bkg` , `plot_ratio` , and the "fit" variants, such as `plot_fit` , `plot_fit_resid` , and `plot_bkg_fit` .
The following preferences are recognized by the matplotlib backend:
Item | Definition |
---|---|
alpha | The transparency value used to draw the line or symbol, where 0 is fully transparent and 1 is fully opaque. |
barsabove | The barsabove argument for the matplotlib errorbar function. |
capsize | The capsize argument for the matplotlib errorbar function. |
color | The color to use (will be over-ridden by more-specific options below). The default is none . |
ecolor | The color to draw error bars. The default is none . |
linestyle | How should the line connecting the data points be drawn. The default is 'None', which means no line is drawn. |
marker | What style is used for the symbols. The default is '.' which indicates a point. |
markerfacecolor | What color to draw the symbol representing the data points. The default is none . |
markersize | What size is the symbol drawn. The default is none . |
xerrorbars | Should error bars be drawn for the X axis. The default is False . |
xlog | Should the X axis be drawn with a logarithmic scale? The default is False . This field can also be changed with the `set_xlog` and `set_xlinear` functions. |
yerrorbars | Should error bars be drawn for the Y axis. The default is True . |
ylog | Should the Y axis be drawn with a logarithmic scale? The default is False . This field can also be changed with the `set_ylog` and `set_ylinear` functions. |
Changes in CIAO
Changed in CIAO 4.13
The id argument has been given.
