Creating charts with QV or QS data hasn't been modified so the steps should be the same. Perhaps your data change coincidently with recent upgrades possibly? This could be work looking into.
In any case, the steps are listed in the help page below and works for QV and QS.
Since you didn't mention which tool you were using, I supplied the three most commonly used tools/instructions for the NPrinting Excel, Powerpoint and Pixel perfect template editors.
Hopefully this guides you in the right direction to achieve your requirement.
