Auto Colouring Based on a Set Membership

[Peter Kelley]

I want to automatically colour elements on a diagram based on whether the element is a member of a set or an intersection of sets. For example all the elements that belong to business units A and B should be green whilst all elements that only belong to B should be yellow.

I'm trying to find a way to do this using tagged values and legends.

The CheckList tagged value type will store the data I want however I am at a loss as to how to reference this in a Legend object.

Multiple boolean tagged values, one for each category, will also encode the data (badly) however I am not sure how to represent each category combination in the legend.

Is there such a thing as a computed tagged value?

In any case can anyone see a solution to this issue?

If you write a script to compute it

I'm pretty new to scripting. Is there a way to trigger a script on element save to compute the value?

Yes. You need to hook to EA_OnContextItemChanged.

You can use several diagram-filters there each filter rule is color the element with right Tagged value.

You can use OR & AND to filter groups to combine different filter sets

I use one set of filter for different element color based on a specific tv and another set of filter for coloring the elements border with a different tv.
That way I can use several filter sets for multi coloring that is based on my own tagged values

Yes. You need to hook to EA_OnContextItemChanged.

So an add in rather than a script?

Yes. You need to hook to EA_OnContextItemChanged.

Yes, unless you use the EA-Matic add-in, which will forward the event to your script.

Looking at the diagram filters I only see options to fade, hide or greyscale elements that do not match the filter or to select those that do. I don't see options to color elements that match the filter. Are you able to explain a little more?

Using "Legend" you can color selected element or connectors just as diagram filter
