python x轴刻度

In some cases, we need to visualize our data within some defined range rather than the whole data. For this, we generally set the x-axis scale within a limit and this ultimately helps us to visualize better. Sometimes, it acts as zooming and a very helpful technique in data visualization. Therefore, Matplotlib has a defined function for this operation ***matplotlib.pyplot.xlim()***.

在某些情况下，我们需要在一定范围内可视化我们的数据，而不是整个数据。 为此，我们通常将x轴比例设置在限制范围内，这最终将帮助我们更好地可视化。 有时，它在数据可视化中充当缩放和非常有用的技术。 因此，Matplotlib为此操作***matplotlib.pyplot.xlim()***定义了函数。

Following is an example showing a different X-axis Limit in plots using [matplotlib.pyplot][].

以下示例显示了使用[matplotlib.pyplot][]在图中不同的X轴限制。

**Syntax:**

**句法：**

matplotlib.pyplot.xlim(left_limit, right_limit )
    plt.show()

![Python | X-axis Scale Limit (1)][Python _ X-axis Scale Limit _1]

![Python | X-axis Scale Limit (2)][Python _ X-axis Scale Limit _2]

## X轴比例限制的Python代码 **(**Python code for x-axis scale limit**)** ##

import numpy as np
    import matplotlib.pyplot as plt
    
    x = np.arange(500)
    y1 = np.arange(500)
    for i in range(500):
        y1[i] = 2*x[i] + np.random.randint(0,56)
    
    plt.figure()
    plt.plot(x,y1)
    plt.xlabel('Number Line')
    plt.ylabel('Function')
    plt.title('Whole Data')
    
    plt.figure()
    plt.plot(x,y1)
    plt.xlim(200,210)
    plt.xlabel('Number Line')
    plt.ylabel('Function')
    plt.title('Limit for X axis is Set')

**Output:**

**输出：**

Output is as figure
