Monthly Evolution for multiple KPis

Hi,

I have the following case: I have multiple KPIs, giving 2 as example. And I want the evolution graph to be visible for each KPIs. In the example below, I have Number of Invoices that meet a set of conditions and Percentage of this invoices from total invoices. And I want the user to see the evolution and the values on the graph without the ones in percentage looking like they are 0. I want the red line from top right to apear in the bottom table. Any ideea how I could accomplish this? 

Blue Line is Sum of invoices where condition is met. And Red Line is Sum of invoices where condition is met divided by Sum of all invoices
