Bokeh 简明教程
Bokeh - Customising legends
图中的各种字形可以通过在默认情况下显示为图区右上角标签的图例属性来识别。可以通过以下属性自定义此图例:
1 |
legend.label_text_font |
将默认标签字体更改为指定的字体名称 |
2 |
legend.label_text_font_size |
font size in points |
3 |
legend.location |
将标签设置在指定的位置。 |
4 |
legend.title |
为图例标签设置标题 |
5 |
legend.orientation |
|
设置为水平(默认)或垂直 |
6 |
legend.clicking_policy |
Example
图例自定义的示例代码如下:
from bokeh.plotting import figure, output_file, show
import math
x2 = list(range(1,11))
y4 = [math.pow(i,2) for i in x2]
y2 = [math.log10(pow(10,i)) for i in x2]
fig = figure(y_axis_type = 'log')
fig.circle(x2, y2,size = 5, color = 'blue', legend = 'blue circle')
fig.line(x2,y4, line_width = 2, line_color = 'red', legend = 'red line')
fig.legend.location = 'top_left'
fig.legend.title = 'Legend Title'
fig.legend.title_text_font = 'Arial'
fig.legend.title_text_font_size = '20pt'
show(fig)
