Time series chart horizontal gridlines through min/max peaks

Question

I am using JFreeChart to plot a timeseries chart. The chart is working fine, but the gridline alignment is becoming a problem.

My requirement is to show the horizontal gridlines through the peak values (i.e for the max and min value). Could you please let me know if there is any property for this, as I am getting grids randomly.

A `TimeSeries` has methods to get the minimum and maximum values. — trashgod, Jan 15 '13 at 15:28

Have you considered using a Marker to highlight the min and max values?

enter image description here

As trashgod sugested you use the Dataset to get the minimum and maximum values and then add a Marker to the Plot

Range range = dataset.getRangeBounds(true);
plot.addRangeMarker(new ValueMarker(range.getLowerBound(),Color.GREEN,new BasicStroke(2.0f)),Layer.BACKGROUND);
plot.addRangeMarker(new ValueMarker(range.getUpperBound(),Color.BLUE,new BasicStroke(2.0f)),Layer.BACKGROUND);

Thanks for the suggestion. Could you please suggest the way to display the corresponding values in the axis. – user1976862 Jan 18 '13 at 09:25
@user1976862 use `Marker#SetLabel` – GrahamA Jan 18 '13 at 11:56
How are you drawing the red line starting from some x1 to x2 in your code? My graph has domain range (Xmin, Xmax). Need to draw line from X1 to X2 given, Xmin – user3552407 May 31 '17 at 10:32
