I am trying to draw heatmap using Jupyter notebook. My table consists of 10 colomns and a lot of rows. The first row is the names of the colomns. I am using plotly lib.
import plotly.offline as py
import plotly.graph_objs as go
import pandas as pd
import numpy as np
import pickle
import matplotlib
import matplotlib.pyplot as plt
from pandas import ExcelWriter
from pandas import ExcelFile
heatmap = go.Heatmap(
z=dfs.corr(method='pearson').as_matrix(),
x=dfs.columns,
y=dfs.columns,
colorbar=dict(title='Pearson Coefficient'),
)
layoutheat = go.Layout(title="title")
figheat = go.Figure(data=[heatmap], layout=layoutheat)
py.iplot(figheat)
dfs is dataframe.
Instead of graphic I get a lot of line like this:
'\ntrace = dict(\n x = x, y = y, z = z,\n type = "scatter3d", \n mode = \'markers\',\n marker = dict( size=5, color=\'black\', line=dict(width=0) ) )\ndata = [trace]\n \nlayout = dict(\n etc
What is the problem?

If you are running a jupyter notebook you need to add py.init_notebook_mode()
after the import. If it still does not work I suggest to reinstall plotly
