Global Configuration Options
============================
PyQtGraph has several global configuration options that allow you to change its
default behavior. These can be accessed using the :func:`setConfigOptions` and
:func:`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 :func:`mkColor` 'd' Default foreground color for text, lines, axes, etc.
background See :func:`mkColor` 'k' Default background for :class:`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).
**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.
