I'm using a bar chart to create a modified Gant chart and thus far all has gone well, and we can display tasks as bars and milestones/risk/issues as symbols. Using the widely available method of creating an expression then classifying it as a text pop-up only while also disabeling the pop-up, for the Bar associated with Tasks. I have been able to create the desired pop-up, but the same method doesn't seem to work for the symbols, and suggestions on a solution.
