Hi all,
I recently start using plotly with Juptyter lab. One of the issue I am facing is jupyterlab slows down when creating 2 heatmap each size around 30Mb. Especially if in jupyterlab I decide to make “Create new output view” I can not do anything once output view create, sometimes browser even crash. I try both with chrome and firefox, I have latest jupyterlab and plotly.
Hi @mtkilic,
You could try using heatmapgl
rather than heatmap
. See https://plot.ly/python/heatmap-webgl/.
Or, you could try using the iframe
renderer as described at Plotly - notebook / Very slow render with many graphs.

Hi @jmmease thank you for the reply.
Using FigureWidget with heatmap
in better than heatmapgl
. Tooltip for heatmapgl
is very slow compare to heatmap
I did try to use iframe
(offline mode) I can see .html files getting created but it wont display on Jupyterlab I get following JS error Uncaught ReferenceError: Plotly is not defined
. I try to pass following at the beginning `%%HTML
` but this didn't solve the issue.
Here is the 3 plot shapes I am trying to display on Jupyterlab at the same time
(3763, 7649)
(7649, 1001)
(3763, 1001)
Thank you in advance for trying to help me out.
Hi @mtkilic,
Just to be explicit, here’s an example of the iframe
renderer approach.
import plotly.io as pio
import plotly.graph_objs as go
pio.renderers.default = 'iframe'
fig = go.Figure(data=[go.Heatmap(z=[[1, 2], [2, 4]])])
pio.show(fig)
Does this example display for you?

Hi @jmmease
Not this doesn’t display anything, however it does create a .html
file under iframe_figures
. I can not open this html file in jupyterlab but I can open from google chrome than I do see the heatmap.
I also see this following error too:
GET http://localhost:8888/files/iframe_figures/plotly.min.js
net::ERR_ABORTED 403 (Forbidden)
Edit: I just try iframe
on Firefox and everything works fine. Its actually much faster too. Looks like chrome is blocking for some reason.
