To draw a line graph using matplotlib, you can follow the steps below:<\/p>\n

    \n
  1. Import the necessary libraries and modules.<\/li>\n<\/ol>\n
    import<\/span> matplotlib.pyplot as<\/span> plt\r\n<\/code><\/pre>\n
      \n
    1. Prepare the data:<\/li>\n<\/ol>\n
      x = [1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span>]  # x\u8f74\u6570\u636e<\/span>\r\ny = [5<\/span>, 7<\/span>, 3<\/span>, 8<\/span>, 4<\/span>]  # y\u8f74\u6570\u636e<\/span>\r\n<\/code><\/pre>\n
        \n
      1. Create a drawing window.<\/li>\n<\/ol>\n
        plt.figure()\r\n<\/code><\/pre>\n
          \n
        1. Create a line graph:<\/li>\n<\/ol>\n
          plt.plot(x, y)\r\n<\/code><\/pre>\n
            \n
          1. Include a title, x-axis label, and y-axis label:<\/li>\n<\/ol>\n
            plt.title('\u6298\u7ebf\u56fe'<\/span>)  # \u6807\u9898<\/span>\r\nplt.xlabel('x\u8f74'<\/span>)  # x\u8f74\u6807\u7b7e<\/span>\r\nplt.ylabel('y\u8f74'<\/span>)  # y\u8f74\u6807\u7b7e<\/span>\r\n<\/code><\/pre>\n
              \n
            1. Display graphic:<\/li>\n<\/ol>\n
              plt.show()\r\n<\/code><\/pre>\n
              In summary, the complete code is as follows:<\/p>\n
              import<\/span> matplotlib.pyplot as<\/span> plt\r\n\r\nx = [1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span>]  # x\u8f74\u6570\u636e<\/span>\r\ny = [5<\/span>, 7<\/span>, 3<\/span>, 8<\/span>, 4<\/span>]  # y\u8f74\u6570\u636e<\/span>\r\n\r\nplt.figure()\r\nplt.plot(x, y)\r\n\r\nplt.title('\u6298\u7ebf\u56fe'<\/span>)  # \u6807\u9898<\/span>\r\nplt.xlabel('x\u8f74'<\/span>)  # x\u8f74\u6807\u7b7e<\/span>\r\nplt.ylabel('y\u8f74'<\/span>)  # y\u8f74\u6807\u7b7e<\/span>\r\n\r\nplt.show()\r\n<\/code><\/pre>\n
              By running the code, you can generate a simple line graph.<\/p>\n","protected":false},"excerpt":{"rendered":"
