Conventionally, the package is imported into the Python script by adding the following statement − from matplotlib import pyplot as plt 1.5.1 is the stable version available. The animation framework foundation consists of the base class QAbstractAnimation, and its two subclasses QVariantAnimation and QAnimationGroup. For the treeview to show as a directory tree, we need to set its model to a QFileSystemModel instance. First import matplotlib and numpy, these are useful for charting. To do this, we use the animation functionality with Matplotlib. Step 4: Install matplotlib from source using setup.py . This gives the red line in Figure 4. closed stops Matplotlib drawing a line between the first and last lines.fill is the colour that goes inside the shape, setting this to None removes it and the edgecolor gives the line it’s colour.. Close. We can set additional options on the tree object: sorting enabled (setSortingEnabled), animation and indention. In order to get matplotlib to recognize the TkInter GUI library, we need to: Step 1: Access our plotting virtual environment via workon plotting . 0 0.005556 90 0.016667 180 0.027778 270 0.038889 360 0.050000 450 0.061111 540 0.072222 630 0.083333 720 0.094444 810 0.105556 900 0.116667 990 0.127778 1080 0.138889 1170 0.150000 1260 0.161111 1350 0.172222 1440 0.183333 1530 0.194444 1620 0.205556 1710 0.216667 1800 0.227778 1890 0.238889 1980 0.250000 2070 0.261111 2160 0.272222 2250 0.283333 2340 … Bug report Bug summary after installing PyQt5, plot function does not work alongside "cv2" (opencv).
