Track user stats over time

[cbachhuber]

Show the evolution of stats over time, to give the room further insights how things are developing.

I would propose that this view is only visible from host side

[cbachhuber]

Plot the shares in some way like

over the entire session time.

Briefly researched how this can be done with pandas and plotly, see https://www.perplexity.ai/search/with-python-plotly-how-can-i-p-CcXFpLcCRqKr.fzt1iv0iQ. That works just fine. Next step: implement!

@BayerC I have one design question: I consider removing the bar chart entirely from the host's view because it somewhat duplicates the time evolution graph. However, the bar chart reacts very quickly to changes in stats. If I do that with the time series (adding a new entry with every run() that's happening every 2s at the moment), we get a lot of data. I see these options:

1. Keep the bar chart for 'real-time' feedback and have a lower sampling frequency in the tracking over time
2. Drop the bar chart from the host's view and do an adaptive temporal sampling: the further a time point is in the past, the less dense the sampling is. The present and maybe last minute is sampled at highest possible frequency.

I tend to option 2 because that's much more elegant, even though it's significantly more complex. What do you prefer? Am I missing an even better option?

[BayerC]

can we make the decision once you implemented the time evolution graph?
Then we see if its still useful /neccesary

[cbachhuber]

At the moment, it looks like

and after 3 users leave like

Getting the graph and the stacked bar chart to align nicely is just hacking around. I'd prefer just dumping the stacked bar in the host view. What's your opinion?

[BayerC]

Hm I'm not sure. although the graph is a really nice feature, its far less intuitive than the stacked bar.

Two ideas:

1. First always youse stacked simple bar, but there is an option to generate a "report" with the graph and maybe all questions
2. The host can switch between the bar (default) and the graph view

WDYT

I'd like to challenge

its far less intuitive than the stacked bar

It's less intuitive, yes. But insufficiently intuitive? I say it's sufficient. It's even easier to understand when you can see it move.

The present is always the rightmost. And when we go for temporally adaptive sampling, we even have an emphasis (more area) for the present. And we could highlight on the x-axis what's the present.

If you still disagree, I'll go with your option 2.

[cbachhuber]

Verbally agreed to go with option 2. Keep the super simple option.

Parametrization: sample once per minute using throttling, limit to 24h.
