###### tags: `Python`

---

**先 import**
`from bokeh.plotting import figure, show`

**第一次使用先pip套件**
`pip3 install bokeh`

**Scatter plot**
定義繪圖板寬高：

`p = figure(plot_width=500, plot_height=500)`

**定義資料：**

x = [1,2,3,4,5,6,7,8,9,10,11]
y = [6,3,7,2,4,6,1,2,3,5,6]

**將資料放到圖上並顯示：**

p.circle(x, y, size=20, color="gray", alpha=0.6)
show(p)

**結果圖：**

**Multiple Lines**

**定義資料：**

x1 = [1,2,3]
x2 = [2,3,4,5,6]
y1 = [5,2,3]
y2 = [2,3,4,1,4]

**使用multi_line()：**

p.multi_line([x1,x2] , [y1, y2],
             color=["firebrick", "navy"], alpha=[0.9, 0.1], line_width=2)
show(p)

**結果圖：**
