# 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.

pyqtgraph.setConfigOptions(**opts)

  Set global configuration options.

  Each keyword argument sets one global option.

pyqtgraph.getConfigOption(opt)

  Return the value of a single global configuration option.
