Pyqtgraph plot pen

Qt使用QColor、QPen、QBrush类来确定如何绘线及填充。这些类功能强大，不过使用并不友好。 PyQtGraph提供了mkColor()、mkPen()、mkBrush()函数来简化创建这些类的过程。. 但是实际使用中，并不需要调用这些函数，任何函数或方法都接收pen或者brush参数，同样实现上述函数的功能。I am trying to plot a red loop (isocurve) that correspond to the level z=2 of a given surface.

Many functions and methods in pyqtgraph accept arguments specifying the line style (pen), fill style (brush), or color.PyQtGraph是纯Python的，只是它底层调用的是PyQt，也就是Qt的Python封装，底层用C/C++语言开发的库，它是在PyQt的基础上开发的 ... how many questions are on the california real estate exam ohio state water bong inscryption animal types cast aluminum lot markers death at funeral division champs venta de carros usados en elizabeth new jersey amd rocm github international truck museum mcb cad drawing yamaha dealers in northern michigan polyphia instagram 10l_1ttl
