Often during the execution of our Matplotlib Program, we will need to update our plot from time to time. Common examples of this are when we need todo plotting in Real-time. In such cases the Plot must be updated very frequently. But how do we do so? There are two methods that you ...
我们可以通过结合使用Cursor Widget和annotate函数来实现这一功能。 importmatplotlib.pyplotaspltfrommatplotlib.widgetsimportCursorfig,ax=plt.subplots(figsize=(8,6))ax.set_title("Cursor with Coordinates - how2matplotlib.com")ax.plot([1,2,3,4],[10,20,25,30],label='Data')ax.set_xlabel('X-axis'...

Matplotlib update plot in loop To update the plot on every iteration during the loop, we can use matplotlib. We constantly update the variables to be plotted by iterating in a loop and then plotting the changed values in Matplotlib to plot data in real-time or make an animation. ...
也可以不创建Figure对象而直接调用接下来的plot()进行绘图,这时matplotlib会自动创建一个Figure对象。 figsize参数指定Figure对象的宽度和高 度,单位为英寸。 此外还可以用dpi参数指定Figure对象的分辨率,即每英寸所表示的像素数, 这里使用默认值80。 因此本例中所创建的Figure对象的宽度为8*80 = 640个像素 plt.figure...
其中,fig是图形窗口对象,update是更新函数,frames是帧数范围,interval是刷新间隔(单位为毫秒)。 显示动画: 代码语言:txt 复制 plt.show() 这样,imshow每秒就会刷新一次,显示新的图像数据。 注意:以上代码中的new_image_data和initial_image_data需要根据实际情况进行替换,可以是图像数组、图像文件路径等。另外,如果需要...
此外，matplotlib还有一个基于图像处理库（如开放图形库OpenGL）的pylab接口，其设计与MATLAB非常类似--尽管...
