Currently when a point's data is not computed we don't draw it on the graphs to clearly show to the users that there are missing values.
But that brings a edge case where there is a computed value between two that are not computed, since we don't display those the one in between will be invisible.
When that case arise we should draw a simple dot for this value since we can't link it to the previous or the next one.
Impacted graphs :
- Project activity graph
- Activity preview graph on project dashboard
