dw_retrieve_chart_metadata does not return color parameters

[janicekchen]

Hello,

I'm trying to retrieve the color key for a chart to apply to a bunch of other charts. When I use dw_retrieve_chart_metadata, it returns all visualization parameters except for color-category. It appears empty. The same thing happens when I download the metadata via CLI and read the JSON into R.

Any suggestions for a fix is appreciated!

Hi @janicekchen

Thanks for bringing up this issue.

You mentioned that you experience the same behavior when downloading via the CLI. Is there any color-category data included in the return from the API at all? This might indicate a flaw with the API.

Is this only happening with choropleth maps?

Thanks!

Hiya!

As far as I recall, there was no color-category data included in the return from the API. I was working with bar charts, not choropleth maps, so I'm not sure if this translates to other viz types.

Thanks @janicekchen

I was able to test this using one of the example datasets. I had to set all colors manually to enable the color-category by switching on Customize colors in the Refine -> Appearance dialogue in Visualize.

This chart results in the correct data being returned from dw_retrieve_chart_metadata():

Could you please retry this?
