Methods Summary

hline(y[, xmin, xmax, linecolor, linestyle, ...])	Draw a line at constant y, extending over the plot.
overplot(*args, **kwargs)	Add the data to an existing plot.
plot([overplot, clearwindow])	Plot the data.
prepare(x, y[, xlabel, ylabel, name])	The data to plot.
vline(x[, ymin, ymax, linecolor, linestyle, ...])	Draw a line at constant x, extending over the plot.

Methods Documentation

static hline(y, xmin=0, xmax=1, linecolor=None, linestyle=None, linewidth=None, overplot=False, clearwindow=True)

Draw a line at constant y, extending over the plot.

overplot(*args, **kwargs)

Add the data to an existing plot.

This is the same as calling the plot method with overplot set to True.

plot

plot(overplot=False, clearwindow=True, **kwargs)

Plot the data.

This will plot the data sent to the prepare method.

Parameters:

• overplot (bool, optional) – If True then add the data to an existing plot, otherwise create a new plot.

• clearwindow (bool, optional) – Should the existing plot area be cleared before creating this new plot (e.g. for multi-panel plots)?

• **kwargs – These values are passed on to the plot backend, and must match the names of the keys of the object’s plot_prefs dictionary.

prepare, overplot

prepare(x, y, xlabel='x', ylabel='y', name='(x,y)')

The data to plot.

Parameters:

• x – The points to plot. The number of points in the two sequences should be the same.

• y – The points to plot. The number of points in the two sequences should be the same.

• xlabel (optional, str) – The axis labels and name for the plot title.

• ylabel (optional, str) – The axis labels and name for the plot title.

• name (optional, str) – The axis labels and name for the plot title.
