我试图在图表上绘制几个点，类似于热图。

示例代码（改编自此处的热图部分）：

import pandas as pd

from bokeh.io import output_notebook, show
from bokeh.models import BasicTicker, ColorBar, ColumnDataSource, LinearColorMapper, PrintfTickFormatter
from bokeh.plotting import figure
from bokeh.transform import transform
import numpy as np

# change this if you don't run it on a Jupyter Notebook
output_notebook()

testx = np.random.randint(0,10,10)
testy = np.random.randint(0,10,10)

npdata = np.stack((testx,testy), axis = 1)
hist, bins = np.histogramdd(npdata, normed = False, bins = (10,10), range=((0,10),(0,10)))

data = pd.DataFrame(hist, columns = [str(x) for x in range(10)])

data.columns.name = …
