Write Image as PDF with Box includes text "Loading [MathJax]/extensions/MathMenu.js"

[vincentliuheyang]

Hi,

I am trying to write plot into PDF format, but I cannot get rid of this box saying "Loading [MathJax]/extensions/MathMenu.js", will you be able to tell me how should I fix it?

Here is the code I am using to generate the plot.

fig = go.Figure()
    fig.add_trace(go.Scatter(x=[0, 1, 2, 3, 4, 5], y=[0.5, 0.6, 0.7, 0.8, 0.9, 0.9], name='A',
                             line=dict(width=4), marker=dict(size=15, symbol='star')))
    fig.add_trace(go.Scatter(x=[0, 1, 2, 3, 4, 5], y=[0.4, 0.4, 0.4, 0.4, 0.4, 0.4], name='B',
                             line=dict(width=4), marker=dict(size=15, symbol='circle')))
    fig.add_trace(
        go.Scatter(x=[0, 1, 2, 3, 4, 5], y=[0.51, 0.52, 0.53, 0.54, 0.55, 0.56], name='C',
                   line=dict(width=4), marker=dict(size=15, symbol='x')))

    fig.update_layout(
        yaxis_range=[0.2, 1],
        legend=dict(
            x=0,
            y=0,
            traceorder="reversed",
            title_font_family="Times New Roman",
            font=dict(
                family="Courier",
                size=16,
                color="black"
            ),
            bgcolor="LightSteelBlue",
            bordercolor="Black",
            borderwidth=2
        )
    )
    fig.write_image("1.pdf")
    fig.show()

What Plotly version are you running? I checked your code with v 5.3.1 (the last one), and no such box is displayed.

I am getting the same box in PDF outputs with Plotly Version 5.3.1

[empet]

I have no idea why that box is displayed. It could be your browser?!!!

[vincentliuheyang]

It only outputs such box if I am trying to write a PDF, the browser does not have such box. One peculiar issue is that if I am going to write multiple PDF plot in one file, this box will only show in the first PDF image.

[nicolaskruchten]

This is pretty unfortunate. The cause is that the PDF is being generated by a browser essentially doing a print operation. If this happens while MathJax is still loading, then this box will appear in the output. @jonmmease any thoughts about how to wait a bit longer?

Just for now, my solution is writing a random plot before my official plot. Of course, I would like to see this problem resolved if possible.

I am having the same issue with plotly 5.4.0 and kaleido 0.2.1.post1. I suspect the issue is with the latest kaleido.

[willfindlay]

I'm also running into this with:

plotly==5.4.0
plotly-express==0.4.1
kaleido==0.2.1

Thanks for the workaround @vincentliuheyang, it works well for me.

[jlehrer1]

Same issue with exact same versions as @willfindlay. Is there any workaround?

[tahashmi]

Thanks to @vincentliuheyang.
@jlehrer1 Try something like this :-) :

import plotly.express as px

#garbage graph
fig = px.scatter(x=[0, 1, 2, 3, 4], y=[0, 1, 4, 9, 16])
fig.show()
fig.write_image("random.pdf")

#actual graph to be replaced
fig1 = px.scatter(x=[0, 1, 2, 3, 4], y=[0, 1, 4, 9, 16])
fig1.show()
fig1.write_image("random.pdf")

[jorgeboucas]

this worked for me:

figure="some_figure.pdf"
fig=px.scatter(x=[0, 1, 2, 3, 4], y=[0, 1, 4, 9, 16])
fig.write_image(figure, format="pdf")
time.sleep(2)

fig=make_figure(df,pa)
fig.write_image(figure, format="pdf")

plotly==5.3.1

[jlehrer1]

Thank you! I hadn't realized it was only on the first write when running a script. Interesting.

[eric-vader]

I am experiencing the same problem as well, do we know what causes the problem?

[nicolaskruchten]

Yes, we know the basic cause, see plotly/Kaleido#122 for details.

Note that if the figure you're rendering doesn't actually use MathJax then you can prevent MathJax from being loaded at all by Kaleido with:

import plotly.io as pio   
pio.kaleido.scope.mathjax = None

Otherwise, if saving a "throwaway" PDF first helps, I would recommend that: basically save your figure twice.
