Composite bar charts should be supported #460

Open camueller opened 11 months ago

camueller commented 11 months ago

Description

Composite bar charts (sometimes also call stacked bar charts) are charts where each bar displays multiple data points stacked in a single row or column. There are situations where no other diagram type can be used to express the intended conclusion. Also the use of 2 diagrams with identical X Axis but different Y axis would not be appropriate. Therefore composite bar charts are rellay needed!

Refer to https://www.goteachmaths.co.uk/composite-bar-charts/

To me it is not quite clear if Mermaid supports this type of diagram at the moment: https://github.com/mermaid-js/mermaid/issues/4269#issuecomment-1868982956

Thanks @camueller how would you expect to define the payloads in the msg for such a chart?

This doesn't really matter to me since I can use a Javascript node for any kind of data transformation.

BTW: Since mermaidcurrently has no support for composite charts I implemented it yesterday and today and created a PR for it: https://github.com/mermaid-js/mermaid/pull/5167 Looking at the other PRs I don't expect a response soon althought I would like it. If you look at this PR you can see the syntax I used for dataset of composite charts: https://github.com/mermaid-js/mermaid/pull/5167/files#diff-15b2d25f41bde2a210201a02bcfd09ba323c9e85136ae309d684aa6c4bcd4dea

I watched your Video about Dashboard 2.0 ( https://www.youtube.com/watch?v=7GTHYzRpQ9M ) and was surprised about your switch to Vue.js. Since 2018 I'm working as developer for one of (or the?) largested Vue.js projects in Europe (50+ devs) :-)
