This is useful when overlaying multiple items. Parameters ---------- mode : ``QtGui.QPainter.CompositionMode`` Composition of the item, often used when overlaying items. Common options include: ``QPainter.CompositionMode.CompositionMode_SourceOver`` (Default) Image replaces the background if it is opaque. Otherwise, it uses the alpha channel to blend the image with the background. ``QPainter.CompositionMode.CompositionMode_Overlay`` Image color is mixed with the background color to reflect the lightness or darkness of the background ``QPainter.CompositionMode.CompositionMode_Plus`` Both the alpha and color of the image and background pixels are added together. ``QPainter.CompositionMode.CompositionMode_Plus`` The output is the image color multiplied by the background.

The data might not be plotted, or there migth be significant performance impact. rDN)r"rL)rQrDs r3setSkipFiniteCheckz PlotCurveItem.setSkipFiniteChecks)-_(= #$r5c(|j|i|y)aP =============== ================================================================= **Arguments:** x, y (numpy arrays) Data to display pen Pen to use when drawing. Any single argument accepted by :func:`mkPen ` is allowed. shadowPen Pen for drawing behind the primary pen. Usually this is used to emphasize the curve by providing a high-contrast border. Any single argument accepted by :func:`mkPen ` is allowed. fillLevel (float or None) Fill the area under the curve to the specified value. fillOutline (bool) If True, an outline surrounding the `fillLevel` area is drawn. brush Brush to use when filling. Any single argument accepted by :func:`mkBrush ` is allowed. antialias (bool) Whether to use antialiasing when drawing. This is disabled by default because it decreases performance. stepMode (str or None) If 'center', a step is drawn using the `x` values as boundaries and the given `y` values are associated to the mid-points between the boundaries of each step. This is commonly used when drawing histograms. Note that in this case, ``len(x) == len(y) + 1`` If 'left' or 'right', the step is drawn assuming that the `y` value is associated to the left or right boundary, respectively. In this case ``len(x) == len(y)`` If not passed or an empty string or `None` is passed, the step mode is not enabled. connect Argument specifying how vertexes should be connected by line segments. | 'all' (default) indicates full connection. | 'pairs' draws one separate line segment for each two points given. | 'finite' omits segments attached to `NaN` or `Inf` values. | For any other connectivity, specify an array of boolean values. compositionMode See :func:`setCompositionMode `. skipFiniteCheck (bool, defaults to `False`) Optimization flag that can speed up plotting by not checking and compensating for `NaN` values. If set to `True`, and `NaN` values exist, the data may not be displayed or the plot may take a significant performance hit. =============== ================================================================= If non-keyword arguments are used, they will be interpreted as ``setData(y)`` for a single argument and ``setData(x, y)`` for two arguments. **Notes on performance:** Line widths greater than 1 pixel affect the performance as discussed in the documentation of :class:`PlotDataItem `.
