i have used ireport tool for creating jrxml template for creating chart(XYLine chart).
and i used this jrxml file in java code to create chart.
Here i passed csv file as data source.
Now i can freely change color,title,subtitle,font ect from java code .
what i want is how to draw a horizontal line in that chart at particular point through java code.
Please suggest me in a right direction.
