Color assignment problems.

Hello everyone,

I’m facing an issue with dynamically assigning colors to rows in my KNIME workflow. I have a table where the row names change dynamically, and I need to ensure each row is assigned a unique color automatically.

The problems I’m encountering with the Color Manager node are:

1.

Fails with Changing Number of Rows: The node sometimes fails when the number of rows changes, especially if there are more rows than before.

1.

Color Repetition: Even with 20 different categories, the Color Manager tends to repeat colors, which defeats the purpose of having distinct colors for each category.

Manually adjusting the colors every time the table content changes is not feasible. I’m looking for a way to automate this process, ensuring that:

• The Color Manager can handle dynamic row names and varying numbers of elements.

• Custom colors can be assigned automatically to each category.

• The Color Manager avoids repeating colors when there are enough colors available in the palette to assign unique colors to each category.

Is there a way to achieve this within KNIME, or perhaps an alternative method to prevent color repetition and handle dynamic changes effectively?

Thanks in advance!
