There is not a simple way to make a pie chart when use a multi-select field like that.
If you are really committed to this pie chart you would have to create a child table where your Project record would have up to five child records, one for each of your selections.
So now the question is how would you initialize this table and how would you keep it maintained?
The table could be initialized manually by running a list of project records are subject to a filter where that multi-select field contained one of the choices. You would manually run that report and copy these records to the child table being sure to map the record idea of the project record into the field related project.
Now, the question is how to maintain this going forward. There are a few ways to do this but I think the best way would be to wait until December 16 when the next release comes out. When it comes out you will be able to use a new feature which would be to copy records into a table. So you would set up the automations first step to delete any child records it may have already had, and then you would have five more automations that would each run conditioned on whether or not the project contain contained one of the five choices. If it did contain one of the five choices it would copy the parent record into the trout record that�s creating one of the children.
Feel free to post back if you get stuck anywhere or else contact me via my website if you would like one on one assistance. This table could be initialized by setting up five automations. Each automation Would run 105 save table to table imports. Each of the save table to table imports would import the project record into the child record and will have a filter to only copy pro jacks where the multi-select field contained one of the 5 choices.
I would suggest that the first step in the automation would be to delete all the trail of records that may or may not already be there. That way you can run the automation every time a parent record is either added or modified or deleted. Then the next steps in the automation would be to run each of the five automations if required.
