Add statistics to the timeline tab #4
Description
A future goal is to add statistics inside the timeline like: average daily codelines and average daily lines.
These can be calculated by taking the sum from all the datapoints from the correct point list and then dividing by the number of points.
These numbers should then be presented in a nice way like a small table.
There would have to be a button to switch the line chart with the table as all the space is already used.
The point lists are currently only iterated in the refreshChart() inside the LineChartPanel.
There the values could be cached on each refresh so we don't have to iterate them somewhere else.
