python 散点图 分类

Visualizing different variables is also a part of basic plotting. Such variables can have different classes, for example, numerical or a category. Matplotlib has an important feature of **Categorical Plotting**. We can plot multiple categorical variables within different types of plots such as line, dot, bar, scatter, etc.

可视化不同的变量也是基本绘图的一部分。 这样的变量可以具有不同的类别，例如，数值或类别。 Matplotlib具有**分类绘图**的重要功能。 我们可以在不同类型的图中绘制多个类别变量，例如线，点，条，散点图等。

**Following are some examples of categorical plotting**:

**以下是分类绘图的一些示例** ：

**Syntax:**

**句法：**

matplotlib.pyplot.figure(figsize=(4,3))
    
    #figsize(float, float)
    width, height in inches.

## 示例1：线图 **(**Example 1: Line Plot**)** ##

![Python | Categorical Plotting (1)][Python _ Categorical Plotting _1]

## 示例2：条形图 **(**Example 2: Bar Plot**)** ##

![Python | Categorical Plotting (2)][Python _ Categorical Plotting _2]

## 示例3：点图 **(**Example 3: Dot Plot**)** ##

![Python | Categorical Plotting (3)][Python _ Categorical Plotting _3]

## 用于分类绘图的Python代码 **(**Python code for categorical plotting**)** ##

# Data Visualization using Python
    # Categorical Plotting
    
    import matplotlib.pyplot as plt
    
    names = ['Rabhes', 'Grpsh J.', 'John C. Dave']
    values = [45646, 75640, 42645]
    
    # example 1
    plt.figure()
    plt.plot(names, values, color='y')
    plt.ylabel('Income')
    plt.title('Income Comparison')
    plt.show()
    
    # example 2
    plt.figure()
    plt.bar(names, values, color='y')
    plt.ylabel('Income')
    plt.title('Income Comparison')
    plt.show()
    
    # example 3
    plt.figure()
    plt.plot(names, values, 'or')
    plt.ylabel('Income')
    plt.title('Income Comparison')
    plt.show()

**Output:**

**输出：**

Output is as figure
