ECharts for Evidence

[Sean Hughes <se...@evidence.dev>]

Hi,

I’m one of the founders of Evidence - a web framework for data analysts. 
I’ve been building charts with ECharts for a few weeks now and have been 
very impressed with your library and your prompt responses for issues on 
Github!

I’m hoping to use ECharts as our main chart library for our product, but 
there are a few issues holding us back from being able to do that. I was 
hoping to hear if you have plans to address these in future versions of 
the product and if so, how high up on your priority list they are.

Because we’re building a reusable framework for our users, we’re not 
able to anticipate all potential situations, and as a result we can’t 
make one-time adjustments (e.g., adding extra padding in one version of 
a chart). Here are the issues we’re having:
Stacking on x-axis with type = value or time (bar and area chart 
stacking do not work consistently)
I believe we may be able to handle this by writing some custom data 
transformation logic to sync the values/times for our data series
Labels getting cut off by chart area (containLabel not covering all 
labels on chart)
Though it wouldn’t be ideal, in the short-term if we could override the 
overflow:hidden option on the DOM container, it would at least stop the 
labels from looking cut off if there is whitespace beside the chart
I’ve created GitHub issues for other things we need in the library, but 
those are minor things that I can work on. These two issues are major 
blockers for us, so I have my fingers crossed that they’re on the 
roadmap.

Let me know what you think.

Thanks!
Sean

Since ECharts is open source you can always try to implement a solution yourself and submit a PR!

All the best,
Dave

Hi Sean.

Thanks a lot for your feedback! About these two issues your mentioned:

Stacking on x-axis with type = value or time


It's a feature that has been mentioned a lot of times in our issue list.
It's still not in our iteration plan but I think we will support it in the
future.

containLabel not covering all
> labels on chart


Optimize label display has been an important topic since 5.0. We are going
to adjust label position to avoid overflow the chart area in our
near versions.

Regards!
