Global Configuration Options

PyQtGraph has several global configuration options that allow you to change its default behavior. These can be accessed using the setConfigOptions and getConfigOption functions:

Option Type Default

leftButtonPan

bool

True

If True, dragging the left mouse button over a ViewBox causes the view to be panned. If False, then dragging the left mouse button draws a rectangle that the ViewBox will zoom to.
foreground See mkColor 'd' Default foreground color for text, lines, axes, etc.
background See mkColor 'k' Default background for GraphicsView.

antialias

bool

False

Enabling antialiasing causes lines to be drawn with smooth edges at the cost of reduced performance.

imageAxisOrder

str

'col-major'

For 'row-major', image data is expected in the standard row-major (row, col) order. For 'col-major', image data is expected in reversed column-major (col, row) order. The default is 'col-major' for backward compatibility, but this may change in the future.
editorCommand str or None None Command used to invoke code editor from ConsoleWidget.
exitCleanup bool True Attempt to work around some exit crash bugs in PyQt and PySide.
useOpenGL bool False Enable OpenGL in GraphicsView.

useCupy

bool

False

Use cupy to perform calculations on the GPU. Only currently applies to ImageItem and its associated functions.
useNumba bool False Use numba acceleration where implemented.

enableExperimental

bool

False

Enable experimental features (the curious can search for this key in the code). In combination with useOpenGL, this makes PlotCurveItem use PyOpenGL for curve drawing.

Caveats

  • Only a very limited subset of the full options of PlotCurveItem is implemented.
  • Single precision is used. This may cause drawing artifacts.
crashWarning bool False If True, print warnings about situations that may result in a crash.

segmentedLineMode

str

'auto'

For 'on', lines are always plotted in segments. For 'off', lines are never plotted in segments. For 'auto', whether lines are plotted in segments is automatically decided based on pen poperties and whether anti-aliasing is enabled.
