Stefan781 opened a new issue, #25464: URL: https://github.com/apache/superset/issues/25464
I have a custom color palette that I would like to use to represent different groups in my charts. Here is the palette: <img width="179" alt="image" src="https://github.com/apache/superset/assets/130654984/92a9496f-8d73-4dc7-89ea-7315ca77dc25";> I have values that are dynamically calculated. I would like to assign the first color to the first value, based on some predefined condition. For example, alphabetical order. I have tried achieving this in multiple ways. When it comes to DeckGL graphs, it proved impossible, since the colors are assigned to their corresponding value in some arbitrary way, which is, to my disappointment, not controlled by the order defined in my dataset, created with a custom SQL query. When it comes to a pie chart, you have the option to _sort by metric_. With some "hacking" of the metric in a way that assigns a number based on the group so that the groups can be sorted in order, I get the desired result:  However, if the metric changes to something meaningful, such as COUNT(*), the colors are still assigned based on the metric, not on my custom order:  Furthermore, even with the first approach, when applying filters, the color order breaks again:  What I would like to be able to is to have a precise rule that defines how are the colors assigned. As a matter of fact, if the colors were assigned based on the defined ORDER BY in the SQL code, I would get my desired result. Are there any workarounds to this problem? Is my approach wrong and is there a better one? If not, are there plans to give more freedom when it comes to assigning colors to the charts? There is also the option to "hardcode" the color from the Dasbhoard settings. This, unfortunately, will not work in my case, since the groups will change dynamically if, for example, the max value becomes 20. I see different use cases for this functionality. The two cases I am interested in are: 1. Monochrome colors for points on a Scatterplot DeckGL visualization based on some metric (for example, older points get a pale color). I actually came up with a workaround to this use case using a rather involved custom JS Interceptor but it still doesn't solve the problem if the user wants a specific color. 2. Monochrome/Analogic colors in Part of a Whole charts for cases where the range of values has a different order than the metric that is used to order them and the represented values can change dynamically. -- This is an automated message from the Apache Git Service.
