使用matplotlib创建图表: 创建一个新的图表,并设置标题和坐标轴标签。 python plt.figure() plt.title('Line Label Example') plt.xlabel('X-axis') plt.ylabel('Y-axis') 在图表中添加线条: 使用plt.plot()函数绘制线条,并为每条线指定一个标签。 python line1, = plt.plot(x, y1, label='Sine Wav...
Let's first create a simple plot to work with: import matplotlib.pyplot as plt import numpy as np fig, ax = plt.subplots(figsize=(12, 6)) x = np.arange(0, 10, 0.1) y = np.sin(x) z = np.cos(x) ax.plot(y, color='blue', label='Sine wave') ax.plot(z, color='black'...
In this initial example, we begin by generating a plot of a sine wave. After creating the plot, thetext()function is employed to add a basic arrow at specific coordinates (arrowXandarrowY). The text string\leftarrow Basic Arrowincludes a left-pointing arrow along with descriptive text. This...
anddrawnowcommand. Thedrawnowcommand updates figures on each callback. To draw an animated plot, you have to use it inside a loop to plot one variable in one iteration and update the figure using thedrawnowcommand. For example, let’s draw the animated plot of a sine wave. See the code...
For example, the array [1.0, 2.0, 3.0, 64.0] will be converted to [0.333, 0.333, 0.333, 64.0]. But for more or less normalized data, the results are really not bad. As an example, let’s draw a sine wave in FP4 format:import matplotlib.pyplot as plt import numpy as np f...
Once again using Scipy, we will load the piano audio and plot the sound wave using Matplotlib. That looks nothing like the pure sine wave in the first section at all even though they are supposed to be of the same note! It’s not as smooth and the magnitude changes. The wave is not...

t = 1:0.01:2; x = sin(2*pi*t); y = cos(2*pi*t); figure subplot(1,2,1) plot(t,x) title('Sine Wave') subplot(1,2,2) plot(t,y) title('Cosine Wave') sgtitle('Two Subplots') Output: In the above code, we used the subplot() function to plot two signals in a figur...
