When you are using Measure Names/Values, there is a single format used for all of the values, so that won't work. There are a couple of workarounds:
- Use Reference Lines. This method lets you do any formatting you want, however, you'd have to generate calculated fields to locate each reference line to center it in each bar.
- Use a dual axis, and put the labels with a different format on the second axis. This gets tricky with Measure Names/Values, and might not be possible. In that case you'd probably want to reshape your data so that all the Fund results are in one column, with the Fund as a dimension.
