Hi @vrg84, I'm curious why we'd want these functions being exported?

these are internal tools that might change at any point

The library doesn’t provide a grouped + stacked bar chart. Since we need this feature, we extended Bar and followed the approach in bar-grouped.ts to a version that suits our needs.

The helpers (generateSVGPathString, getProperty, flipSVGCoordinatesBasedOnOrientation, mergeDefaultChartOptions, updateLegendAdditionalItems) have some non-trivial logic. I figured that reimplementing them outside the library risks inconsistencies if they change.

The goal of using the same helpers is keeping our custom chart behavior visually and functionally consistent with the library.

@vrg84 why not contribute the grouped stacked bar chart instead?

I wish i could, i just dont have the time right now take it to where it needs to be. Its at a bare minimum to fit our needs.

Having said that, i do realize the exposed tools are only ever used in creating a new chart / extending the functionality... i'll see if i can make time to create a proper issue for it instead and start/share the work, maybe more people can contribute.

would you like to share your current code that achieves the grouped+stacked bar functionality? and maybe I could get it into the library, no promises though 🙂

Yes! I have no expectations since it seems like theres still a lot of work to do, but I ported it into my fork:
https://github.com/vrg84/carbon-charts/tree/grouped-stacked-bar-chart

I've taken some steps to make it run with a simple example (located in
https://github.com/vrg84/carbon-charts/blob/grouped-stacked-bar-chart/packages/docs/src/lib/bar/examplesGroupedStacked.ts

But like i said, this implementation was tailored to our needs (it was the best i can do in a few days), this is still missing from the top of my head:

• Extended tooltip, its not clear now which "stack" you are looking at. We've customized it with the customHTML tooltip but i guess there should be a default for it
• Table view has not been implemented
• CSV export has not been implemented
• Only the vertical orientation works like it should
• Only the labels scaleType has been tested

It was fun diving into the library and d3.js for a bit 😄thanks for your time!
