I am trying to create a heatmap. The code:
import plotly.express as px
fig = px.imshow(data.corr().values)
fig.update_layout(
title="Correlation matrix",
xaxis_title="X",
yaxis_title="Y",
coloraxis_colorbar=dict(
title="Your Title",
))
fig.show()
The plot:
You can specify the size of your Figure explicitly to remove this white space if you don't want it. For example:
import numpy as np
import pandas as pd
import plotly.express as px
data = np.random.randn(10, 10)
data = pd.DataFrame(data)
fig = px.imshow(data.corr().values)
fig.update_layout(
title="Correlation matrix",
xaxis_title="X",
yaxis_title="Y",
coloraxis_colorbar=dict(
title="Your Title"),
width = 700, height = 700,
autosize = False)
fig.show()
produces
