why don't you use SDK examples.
If you use number on x-axis, you need to change CategoryAxis to LinearAxis ans set maximum and minimum to 32 and 36.
Let me tell you my requirement clearly. I want to display rectangular bars ( that looks like a column chart) Starting from a range say 32 and ending to a range 36 ( both 32 & 36 on x-axis) I donot want to use columnwidthratio .because if i use them it initially shows correctly but when I scroll/zoom the display & range setting is not correct.
I can't understand where is a problem.
Can you create a screen with existing Chart and write on it what you whant to change.
