交互式繪圖

##交互式繪圖
from plotly.graph_objs import Scatter,Layout
import plotly
import plotly.offline as py
import numpy as np
import plotly.graph_objs as go

## 製作折線圖
N = 100
random_x = np.linspace(0,1,N)
random_y0 = np.random.randn(N)+5
random_y1 = np.random.randn(N)
random_y2 = np.random.randn(N)-5

#Create traces
trace0 = go.Scatter(
    x = random_x,
    y = random_y0,
    mode = 'markers',
    name = 'markers'
)
trace1 = go.Scatter(
    x = random_x,
    y = random_y1,
    mode = 'lines+markers',
    name = 'lines+markers'
)
trace2 = go.Scatter(
    x = random_x,
    y = random_y2,
    mode = 'lines',
    name = 'lines'
)
data = [trace0,trace1,trace2]
py.iplot(data)

##製作散點圖
##把mode設置爲markers就是散點圖，然後marker裏面設置一組參數，比如顏色的隨機範圍，散點的大小，還有圖例等等。
trace1 = go.Scatter(
     y = np.random.randn(500),
    mode = 'markers',
    marker = dict(
        size = 16,
        color = np.random.randn(500),
        colorscale = 'Viridis',
        showscale = True
    )
)
data = [trace1]
py.iplot(data)
