Row Evolution is an awesome feature of Piwik. This ticket is about adding support for Goals and Ecommerce reporting within Row evolution.
Goals are a key report that users will want to know about historically. There is huge value in reporting metrics of "Goal Revenue, Ecommerce revenue" and then per Goal metrics: "Goal %s revenue", "%s conversions", conversation rate for 1 or all goals, over time, for any given report with Goal metrics.
Example use case: "compare the ecommerce revenue for the top 4 search keywords or entry Pages over time".
With this new "Goal selector", a user can see the evolution of "Conversion rates" for specific keyword of website partners. Common use case: Multi-Row-Evolution plot the custom variables values for "userType" custom variable, then select "Goal #2" and "Metric: Revenue" and you can see revenue per user type, over time, Nice!
