Line, Fill, and Color
|
|
=====================
|
|
|
|
Many functions and methods in pyqtgraph accept arguments specifying the line style (pen), fill style (brush), or color.
|
|
|
|
For these function arguments, the following values may be used:
|
|
|
|
* single-character string representing color (b, g, r, c, m, y, k, w)
|
|
* (r, g, b) or (r, g, b, a) tuple
|
|
* single greyscale value (0.0 - 1.0)
|
|
* (index, maximum) tuple for automatically iterating through colors (see functions.intColor)
|
|
* QColor
|
|
* QPen / QBrush where appropriate
|
|
|
|
Notably, more complex pens and brushes can be easily built using the mkPen() / mkBrush() functions or with Qt's QPen and QBrush classes::
|
|
|
|
mkPen('y', width=3, style=QtCore.Qt.DashLine) ## Make a dashed yellow line 2px wide
|
|
mkPen(0.5) ## solid grey line 1px wide
|
|
mkPen(color=(200, 200, 255), style=QtCore.Qt.DotLine) ## Dotted pale-blue line
|
|
|
|
See the Qt documentation for 'QPen' and 'PenStyle' for more options.
|
|
Colors can also be built using mkColor(), intColor(), hsvColor(), or Qt's QColor class
