Many times while plotting a figure, we have to compare different functions simultaneously. Then we do have the option to plot in a single figure but this is helpful only for a limited number of functions. If there are a greater number of functions, then plotting in the same figure turns out to be messy. Therefore, matplotlib provides a feature of subploting in which we can plot more than one plot in one figure with more than one graph. This is one of the most often used tools for best data visualization and the figure shows an example.

绘制图形很多时候，我们必须同时比较不同的功能。 然后，我们确实可以选择绘制单个图形，但这仅对有限数量的功能有用。 如果有更多的功能，则在同一图中绘制会变得很混乱。 因此，matplotlib提供了细分功能，其中我们可以在一个图形中绘制多个图形，并在多个图形中绘制图形。 这是实现最佳数据可视化的最常用工具之一，该图显示了一个示例。

**Syntax:**

**句法：**

#plotting in a one figure
    plt.figure()
    
    #upper part of subplot
    plt.subplot(2, 1, 1)
    plt.plot(x1, y1, 'yo')
    plt.title('SubPlot Example')
    
    #lower part of subplot
    plt.subplot(2, 1, 2)
    plt.plot(x2, y2, 'go')
    plt.xlabel('time (s)')
    plt.ylabel('Undamped')
    
    plt.show()

![Python | Vertical Subplot (1)][Python _ Vertical Subplot _1]

**Note:** Both the graphs are independent, as the following figure(1) adds grid to one graph and the other remains the same and furthermore in figure(2), both have grid.

**注意：**两个图都是独立的，因为下图(1)将网格添加到一个图，另一个图保持不变，此外在图(2)中，两个图都具有网格。

![Python | Vertical Subplot (2)][Python _ Vertical Subplot _2]

## 垂直子图的Python代码 **(**Python code for vertical subplot**)** ##

# Data Visualization using Python
    # Vertical Subplot
    
    import numpy as np
    import matplotlib.pyplot as plt
    
    x1 = np.linspace(0.0, 5.0)
    x2 = np.linspace(0.0, 2.0)
    
    y1 = np.cos(2 * np.pi * x1) * np.exp(-x1)
    y2 = np.cos(2 * np.pi * x2)
    
    plt.figure()
    plt.subplot(2, 1, 1)
    plt.plot(x1, y1, 'yo')
    plt.title('SubPlot Example')
    plt.ylabel('Damped oscillation')
    
    plt.subplot(2, 1, 2)
    plt.plot(x2, y2, 'go')
    plt.xlabel('time (s)')
    plt.ylabel('Undamped')
    
    plt.show()
    
    
    #Applying grid to one
    plt.figure()
    plt.subplot(2, 1, 1)
    plt.plot(x1, y1, 'yo')
    plt.title('Figure 1')
    plt.ylabel('Damped oscillation')
    plt.grid()
    plt.subplot(2, 1, 2)
    plt.plot(x2, y2, 'go')
    plt.xlabel('time (s)')
    plt.ylabel('Undamped')
    
    plt.show()
    
    
    #Applying grid to both
    plt.figure()
    plt.subplot(2, 1, 1)
    plt.plot(x1, y1, 'yo')
    plt.title('Figure 2')
    plt.ylabel('Damped oscillation')
    plt.grid()
    plt.subplot(2, 1, 2)
    plt.plot(x2, y2, 'go')
    plt.xlabel('time (s)')
    plt.ylabel('Undamped')
    plt.grid()
    plt.show()
