Limit for Scattergl Figures = 8?

Dash Python
1

Hi all,

I am using go.Scattergl on my scatter graphs and noticed that there seems to be a maximum number of rendered plots. No more than eight graphs can be rendered at the same time. Can this be configured somewhere?

Here is an example:

import dash
from dash import dcc
from dash import html as html
import plotly.graph_objects as go
import pandas as pd

external_stylesheets = ["https://codepen.io/chriddyp/pen/bWLwgP.css"]
app = dash.Dash(__name__, external_stylesheets=external_stylesheets)
df = pd.read_csv(   "https://gist.githubusercontent.com/chriddyp/5d1ea79569ed194d432e56108a04d188/raw/a9f9e8076b837d541398e999dcbac2b2826a81f8/gdp-life-exp-2007.csv"
)

figs = []

for k in range(12):
    fig = go.Figure()
    fig.add_trace(
        go.Scattergl(
            x=df["gdp per capita"],
            y=df["life expectancy"],
        )
    )

    figs.append(dcc.Graph(id="life-exp-vs-gdp_" + str(k), figure=fig))

app.layout = html.Div(figs)
if __name__ == "__main__":
    app.run_server(debug=True)

Seems to be related to the open issue Using a shared webgl context across graph divs (e.g for dashboard apps)? · Issue #2333 · plotly/plotly.js · GitHub, maximum webgl contexts in the browser

In Chrome, you can configure the maximum number of contexts via

–max-active-webgl-contexts=
