Bug description

Repro steps:

1. Create a mixed chart
2. In one of the queries, set the metric to use a number. In the other, set it to use a %
3. In the Customize tab, set the Primary y-axis format and Secondary y-axis format. One should use something numeric and the other should use something with a %
4. Hover over the tooltips on the chart

Current behavior:
The numeric value is showing as a %. Instead of showing 4724163, it's showing 472416260.0%

Expected behavior:
The tooltip displays should match the correct formatting as the axis

Note: repro steps use a % for the secondary y axis but this can be reproduced with other formats in the secondary y axis field
