Dynamic selection of legend & value in charts so users can customize charts

It should be possible for end-users to customize the chart legend & value, based on several options provided by the developer of the report.

For example in a datamodel with Sales and Net Sales as measures and Channel and Country as columns a developer creates a report showing a chart with sales over time with Channel as the legend.

The developer should be able to let the user change the measure to Net Sales and the legend to country so the chart will show Net sales over time with Country as the legend.

A user is now able to customize their chart(s) instead of only filtering based on slicers or filters. This greatly improves the usability and reduces the need for multiple charts or even pages.
