1.3.3.1 qwt.qplt.Plot

class Plot( *arguments)

Plot takes any number of optional arguments. The data-directed interpretation of each optional argument is:

Axis, to enable and redefine an axis.
Curve, to add a curve to the plot.
QString or a string, to set the title of the plot.
int, to attach a set of mouse events to the zoomer actions.
(int, int), to set the size of the plot.

Plot has an infinite deep stack of zoom regions. You can:

select a zoom region
unzoom all
walk down the stack
walk up the stack.

Plot uses __getattr__() to inherit all methods of QwtPlot.

In addition, the class Plot defines the following methods:

clearZoomStack( self): Force autoscaling and clear the zoom stack.

formatCoordinates( self, x, y): Format mouse coordinates as real world plot coordinates.

getZoomerMouseEventSet( self): Return the index of the set of mouse events attached to the QwtPlotZoomer actions.

gracePlot( self): Clone the plot into Grace for very high quality hard copy output.

plot( self, *curves): Plot a list of curves.

plotAxis( self, orientation, options, title): Plot and enables an axis.

plotCurve( self, curve): Plot a single curve.

setZoomerMouseEventSet( self, index): Attach the QwtPlotZoomer actions to set of mouse events.

toggleCurve( self, key): Toggle a curve between hidden and shown.
