如何在 Bokeh 中绘制多线时间序列？ 我使用下面的两对 x 和 y 得到了一个没有绘图的空图表:
x1 = ['2017-03-15', '2017-03-16', '2017-03-17', '2017-03-18', '2017-03-19']
y1 = [0.02, 0.02, 0.02, 0.01, 0.0]
x2 = ['2017-03-20', '2017-03-21', '2017-03-22', '2017-03-23', '2017-03-24']
y2 = [0.23, 0.24, 0.25, 0.25, 0.27]
#converting x-axis to datetime
x1 = [datetime.strptime(date, "%Y-%m-%d") for date in x1]
x2 = [datetime.strptime(date, "%Y-%m-%d") for date in x2]
# create a new plot with a title and axis labels
p = figure(title="my Chart", x_axis_label='date', y_axis_label='percentage', x_axis_type='datetime',tools=TOOLS)
p.multi_line(xs = [x1, y1] , ys = [x2, y2], color=['red','green'])
html = file_html(p, CDN, "my plot")
最佳答案
您在 p.multi_line 方法中设置的 xs 和 ys 参数不正确。
试试这个:
p.multi_line(xs = [x1, x2] , ys = [y1, y2], color=['red','green'])
