Stumbled on a giant cow artificial intelligence course, could not help but share to everyone. Tutorial is not only a zero-based, user-friendly, and very humorous, like watching a fiction! I think too much bad, so to others. Tutorial links: https://www.cbedai.net/qtlyx
Recently made a thing, began with pyqt, think about this before use, have been for several years.
pyqt which drawing is very troublesome thing, matplotlib is said to refresh a lot of trouble? Anyway pyqtgraph and pyqt is a, well compatible, and can be perfectly embedded.
Embed the way is also very simple.
1：
In the above plus a first ui Layout, such verticalLayout
The red it is.
2：
import pyqtgraph as pgThen init function of the window,
self.plot = pg.PlotWidget(enableAutoRange=True)
self.ui.verticalLayout.addWidget(self.plot)
self.curve = self.plot.plot()This happen, we put a drawing of the object bound to the verticalLayout up.
3：
When we want to draw something of it, pass parameters directly on it, or np general transfer array series of pandas will do,
self.curve.setData(data)4：
If this thing is also updated, such as a second refresh time, then clear it before drawing.
self.curve.clear()
