Ok thanks. I wanted to add and update information in the first post as lots of it is outdated.

A general question: Does someone know how to edit posts on this forums? Quite sure a while ago I managed to do that. Did something change or ist it generally not possible anymore?

If you think there is a bug you can always post minimal runnable code that reproduces the problem and I will look into it.

I am sorry, since I am not using notebooks I can not really help here. Interesting is that someone not using notebooks was having the same problem about the missing toolbar:
https://community.backtrader.com/post/13521

I think that highly depends on how you implemented it but in general I would say: no.

Well, that is interesting. The point is that we are talking about a static HTML-file. So I am wondering if the HTML is correct but you still don't see the toolbar if you the HTML you generate differs from mine.

Do you see the toolbar when you navigate your browser here?

Could you please run the demo "blackly_single" and send me the output HTML?

@vbs Thank you for the quick reply! I did look on the right side of the plot, but no toolbar there. Also it doesn't plot in tabs even if I use the "multi" option. feel like something weird is going on with my setup. I am using windows10 + bokeh 2.0.2 + backtrader_plotting 1.1.0.

I do see in backtrader_plotting requirements says bokeh ~= 2.0.0. Wondering if anything in 2.0.2 breaks it?

Requirement already satisfied: bokeh~=2.0.0 in c:\users\yang fu\appdata\roaming\python\python37\site-packages (from backtrader_plotting) (2.0.2)

b = Bokeh(style='bar', plot_mode='multi', scheme=Tradimo())
cerebro.plot(b)

I dont't think that Bokeh 2.0.2 breaks it. Cannot say whats wrong there. I would suggest you start with a new/clean Python environment to test with.

Hello @vbs , sorry to bother you again. Would like to ask you another question. The Interactive Plot is now shown in the cell (jupyter notebook) instead of a new browser. Is this the expected behavior? Below is my code. I have tried all output mode - show, memory, save, but I also couldn't see any file being saved.

Sorry I have never used notebooks and cannot help here.

@Yang-Fu said in Bokeh Integration - Interactive Webbrowser Plotting:

Hi @vbs, Excellent work! Really grateful for this nice tool. I do have a question about zoom, how can I do that? I see in the earlier replies you said there will be a toolbar on the left, but I don't see one in my plots.

Take a look at one of the demos please:
https://verybadsoldier.github.io/backtrader_plotting/demos/blackly_single.html

You will find the toolbar on the right (a bit cropped sadly):

@vbs tks for your reply. I tried commenting out the lines under metadata.py but still having the same error. Full stacktrace provided below:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
~\anaconda3\envs\env_backtrader\lib\site-packages\backtrader_plotting\html\metadata.py in _get_strategy(strategy)
     67 
     68         # md += 'Source Code:\n'
---> 69         # md += f'\n```\n{inspect.getsource(strategy.__class__)}\n```\n\n'
     70 
     71 

Well, according to your stacktrace the code gets execute even though commented out :) I have no good idea about that, sorry. I would suggest to debug that. That line should not be executed.

Please try to comment out these two lines in the backtrader_plotting sources:

    md += 'Source Code:\n'
    md += f'\n```\n{inspect.getsource(strategy.__class__)}\n```\n\n'

I will provide a config option in future versions.
