Inherited from object: __class__

Method Details

__init__(self, parent=None, background='white', font=None, zoom=False, select=None)
(Constructor)

 

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

Parameters:
  • parent - the parent widget
  • background (str) - the background color
  • font (QFont) - the font for axis labels, default: 10 point Helevetica
  • zoom (bool) - a flag that indicates whether interactive zooming (using the left mouse button) is enabled; the default is False (no zoom)
  • select - enables the user to select a range along the x axis by dragging the mouse (with the left button pressed) in the area under the x axis. If select is 0, no selection is possible. Otherwise the value of select must be a callable object that is called whenever the selection changes, with a single argument that can be None (no selection) or a tuple containing two x values.
Overrides: object.__init__

draw(self, graphics, xaxis=None, yaxis=None)

 

Draw something on the canvas

Parameters:
  • graphics - the graphics object (PolyLine, PolyMarker, or PlotGraphics) to be drawn
  • xaxis - None (no x-axis), "automatic" (automatic scaling), or a pair (x1, x2) defining the range of the x-axis
  • yaxis - None (no y-axis), "automatic" (automatic scaling), or a pair (y1, y2) defining the range of the y-axis

mouseMoveEvent(self, event)

 
Overrides: qt.QWidget.mouseMoveEvent

mousePressEvent(self, event)

 
Overrides: qt.QWidget.mousePressEvent

mouseReleaseEvent(self, event)

 
Overrides: qt.QWidget.mouseReleaseEvent

paintEvent(self, event)

 
Overrides: qt.QWidget.paintEvent

resizeEvent(self, event)

 
Overrides: qt.QWidget.resizeEvent

select(self, range)

 

Highlight a range on the x-axis

Parameters:
  • range - the range on the x-axis to be highlighted. It can be None (no selection) or a sequence of two values on the x-axis.
