Jfreechart place text/annotations/labels on desired position and line over outline of the chart
I'm trying to recreate a chart similar to the one in the following picture:
For the moment, I managed to get this:
How to add missing elements e.g axis labels out of setLabelLocation() method allowed boundaries. Also how to add value labels on shown positions?
And for the last green vertical line it seems that the line is covered by the dashed outline, here I tried to plot a secondary axis at the right side of the chart but the line is still in background, any idea to solve that?
Here is the code of the attempt :

Solution
As discussed here, one way to get the desired axis markings is to add a SymbolAxis on the right, as illustrated here and below. In addition,
The axis/plot overlap may reflect the use of
RectangleInsetsinsetAxisOffset(), omitted below; a third domain marker is shown instead.Tick mark position support is provided by
DataAxisandDateTickMarkPosition.Instead of padding titles with spaces, use
setPadding(), seen here and below.Adjust the chart's overall size as shown here.
In a Swing context, construct and manipulate GUI objects only on the event dispatch thread.
