To add a chart to your favorites simply click on the star on the left of the chart. It should turn yellow when it's added. To remove from favourites repeat the process.
To access the charts in your favourites click the star tab on the left. These can be dragged and moved so you can order them as appropriate.
The idea of the favourites tab is to correlate indicators such as :
- the effect of each performance peak on your conversion rate by correlating the view 'conversion rate' and 'web scenario'
- the effect of your traffic peaks on your server load by correlating your 'Infrastructure Cost per Click' (ICC) and your 'Performance' chart.
- the effect of your page loading time on your page views by correlating your web scenarios with page views from Analytics.
