補充知識：python plotly line chart 折線圖

我就廢話不多說了，還是直接看程式碼吧！

# 1 折線圖資料
# trace1 - 基本格式
# trace2 - 更多引數
trace1 = go.Scatter(
 x = x1,y = y2,)
trace2 = go.Scatter(
 x = x2,mode = 'lines',# 模式：lines 線，markers 點。可用“+”相連
 name = 'line2',# 折線名，顯示於圖例
 connectgaps = True # 連線缺失點兩端 預設False
 line = dict(
  color = ('rgb(205,12,24)'),# 顏色
  width = 4,#線寬
  dash = 'dash') # 虛線： dash 一一，dot ···，dashdot 一·一
) 
)

# 2 打包資料
data = [trace1,trace2]

# 3 格式
layout = dict(title = '折線',xaxis = dict(title = '時間'),# 橫軸座標
    yaxis = dict(title = '數量'),# 總軸座標
    legend=dict(x=1.1,y=1) # 圖例位置 
    )

# 4 打包資料+格式
fig = dict(data=data,layout=layout)

# 5 畫圖
py.iplot(fig,filename='styled-line')

以上這篇Python openpyxl 插入折線圖例項就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支援我們。
