        PlotProxy

Known Subclasses:

hsi.hsi_major_mode.HSIPlotMinorMode

Proxy object that represents a bunch of lines to be plotted in a MultiPlotter.

Instance Methods

__init__(self)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature

getLines(self, *args)
Users should override this to return a list of plot.Polyline instances that represent the data to be plotted.

updateLines(self, *args)
Called by other objects to reset the internal state of the PlotProxy.

addListener(self, plotter)
Add a MultiPlotter as a listener.

getListeners(self)
Returns the list of MultiPlotter listeners

updateListeners(self, skip=[])
Force any listeners to update their plots

updateListenerExtrema(self)
Update the extrema of any listeners

Method Details

init(self)
(Constructor)

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__: (inherited documentation)

getLines(self, *args)

Users should override this to return a list of plot.Polyline instances that represent the data to be plotted.

The x and y values are optional and are dependent on the user application to have passed them in through updateLines.

updateLines(self, *args)

Called by other objects to reset the internal state of the PlotProxy.

Coordinates x and y can optionally be specified in case the user proxy needs to do something on a user click of those coordinates.

addListener(self, plotter)

Add a MultiPlotter as a listener.

It's possible that more than one MultiPlotter will be interested in the same data. This keeps track of which plotter is interested and updates them when the data changes.
