How to create a graph with multiple axis

Hi, 

i need your help. I would like to create a graph based on the following:

I would like to show the average spent time per visited page on my intranet site, within a specific time period. So as i can understand i have three values, the visited pages that i need to show on the graph, the average spent time as a value and somehow i have to include (probably on thje y axis) the days in order for the user to use slicer and when the period changed the graph must be recalculated.

Any suggestions?
