Run this project i get graph with x- axis value:
1,2,3,4,5....
But I want to print value:
2005,2006,2007,2008.....
I changed in some code like:
setChartSettings(renderer, "Yearly revenue in the last "+count+" years", "Years", "revenue in $", 2005,
2010, 0, 24000, Color.GRAY, Color.LTGRAY);
and run project i get value of x-axis like:
2005,2006,2007....
but not get graph bar value. Values of all x-axis are null. How can I make this work?
