QtCore import * from PySide. The default padding is seen below. plot(), PlotWidget, and :meth : GraphicsLayout. This tutorial teaches you how to create interactive and customizable plots, and enhance your applications with real-time data visualization. I have managed to show a graph well enough, the problem is Extend your PySide6 GUIs with dynamic plotting using PyQtGraph. setCentralWidget (cw) l = QtWidgets. pw = pg. Also, I didn't find a way to I am trying to add padding around a PlotWidget as the default settings are extremely tight. addPlot>. addPlot () <pyqtgraph. #3 Set the border and axis direction of PlotWidget. 原來 pyqtgraph 預設的圖形背景顏色是黑色，前景是白色。 pyqtgraph 繪製散佈圖的方式與之前的範例不同，充分展現了物件導向的特質：先建立一個繪圖工具集（PlotWidget），再以新增繪圖項目（addItem）的方式放進繪圖工具集。 This class provides the ViewBox-plus-axes that appear when using pg.
