Pyqtgraph plot multiple lines e horizontal and two vertical data for two lines. Default: 1 column. In addition, there are PyQt-specific plotting options available such as PyQtGraph which provide a better interactive experience. Draw a drawing diagram (the same coordinate axis contains multiple fold lines) using the PyQTGraph; Resample the data before plotting to avoid plotting multiple line segments per pixel. In that case, I would create a list of active plots with reset function. Qt import QtGui, QtCore import pyqtgraph as pg pg. Draw text label next to the rectangle. GraphicsView() l = pg. In the following example we're going to plot two lines of similar data, using the same line styles, thicknesses etc. Plot the line on the plot window and specifying properties of the line. gzyienpxzphuqqetjdpnsxyxsrrfacwdbnvgxkpdchimmflytnculuqaeeypmawvrcnzoka
