But autonumberhash128 is not available for expressions in charts
How could I get a consistent string to number hash functiont in chart expressions? Is there another way to have it working?
I thought about calculating it during the loading script. But I have the feeling that it is not a good idea to combine data with representation; and unnecessarily increase the amount of data loaded in memory:
NAME as CLIENT_NAME,
autonumberhash128(NAME) as CLIENT_COLOR
For 'using the same consistent colors throughout the application' you can use master dimensions. When you created one for your dimensions, click on them again and then you can use color scheme for each value.
