Method Details [hide private]

__init__(self)
(Constructor)

source code 

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

Overrides: object.__init__
(inherited documentation)

_do_draw_graphs(self, context, rect)

source code 

Draw all the graphs.

Parameters:
  • context (cairo.Context) - The context to draw on.
  • rect (gtk.gdk.Rectangle) - A rectangle representing the charts area.

_do_draw_axes(self, context, rect)

source code 

Draw x and y axis.

Parameters:
  • context (cairo.Context) - The context to draw on.
  • rect (gtk.gdk.Rectangle) - A rectangle representing the charts area.

draw(self, context)

source code 

Draw the widget. This method is called automatically. Don't call it yourself. If you want to force a redrawing of the widget, call the queue_draw() method.

Parameters:
  • context (cairo.Context) - The context to draw on.
Overrides: gtk.Widget.draw

add_graph(self, graph)

source code 

Add a graph object to the plot.

Parameters:
  • graph (line_chart.Graph) - The graph to add.

remove_graph(self, name)

source code 

Remove a graph from the plot.

Parameters:
  • name (string) - The name of the graph to remove.

set_xrange(self, xrange)

source code 

Set the visible xrange. xrange has to be a pair: (xmin, xmax) or RANGE_AUTO. If you set it to RANGE_AUTO, the visible range will be calculated.

Parameters:
  • xrange (pair of numbers) - The new xrange.

set_yrange(self, yrange)

source code 

Set the visible yrange. yrange has to be a pair: (ymin, ymax) or RANGE_AUTO. If you set it to RANGE_AUTO, the visible range will be calculated.

Parameters:
  • yrange (pair of numbers) - The new yrange.
