我有一个包含两列的数据框：<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
alert("Hello");
});
});
</script>
和x_att1。 y_att1包含int或float。如果y_att1包含数字作为字符串，那么我可以绘制x_att1。但如果y_att1包含字符串，则不会绘制任何内容。我不知道为什么。这是一个错误还是一个功能？我用散景0.10.0
代码1，数字为x_att1的字符串（有效）：
x_att1代码2，字符串位于from bokeh.plotting import figure, output_file, show
from bokeh.models import LinearAxis, Range1d
import pandas as pd
output_file("bars.html")
df = pd.DataFrame()
df['y_att1'] = [0.70,0.68,0.50,0.48,0.30,0.28]
df['x_att1'] = ['0','4','2','7','3','1']
p = figure(title="twin y-axis bar example", x_range=df['x_att1'].values.tolist())
p.quad(bottom=0, top=df['y_att1'], left=df['x_att1'].values.tolist()
, right=df['x_att1'].values.tolist(), line_width=7, line_color='red')
p.yaxis.axis_label = 'left y axis'
p.yaxis.axis_label_text_color = 'red'
p.xaxis.axis_label = 'x axis'
p.xaxis.axis_label_standoff = -5
show(p)
（不起作用）：
x_att1代码3包含from bokeh.plotting import figure, output_file, show
from bokeh.models import LinearAxis, Range1d
import pandas as pd
output_file("bars.html")
df = pd.DataFrame()
df['y_att1'] = [0.70,0.68,0.50,0.48,0.30,0.28]
df['x_att1'] = ['b','d','a','h','f','e'] #changed only this line
p = figure(title="twin y-axis bar example", x_range=df['x_att1'].values.tolist())
p.quad(bottom=0, top=df['y_att1'], left=df['x_att1'].values.tolist()
, right=df['x_att1'].values.tolist(), line_width=7, line_color='red')
p.yaxis.axis_label = 'left y axis'
p.yaxis.axis_label_text_color = 'red'
p.xaxis.axis_label = 'x axis'
p.xaxis.axis_label_standoff = -5
show(p)
的字符串和一些技巧（有效）：
x_att1美好的一天！
