The solution provided works but produces overlapping graph between datasets.

Below is the output of my current code, which is plotting only "createXYStepDataset()" i need to plot as well "createXYStepDataset2()" in same window. Please guide. https://drive.google.com/file/d/0B_7NwaeesYP0QnlmcUlFbHdldVk/view?usp=s...

Thank you very much .. able to generate now

Hi, thanks for reply.. can you please tell where to edit exactly in my code.. i am newbie to jfreechart

I am unable to get desired output while using the suggested solution.

I am using XYStepChart from jFreeChart, couldn't able to get output graph for x-axis in numberical, instead i am getting in time format? Attached my code snippet here, i am using XYStepChart from chart factory. The x-axis scale at output for the code is being displayed in scale of eg: 05:30:00:00, 0...

I was using JFreeChart with code containing barChartData.setValue(10,"T1", "1"), which gives only varying y-axis parameters. Please see the attached image. I need bar width being changed based on input variable; Y-axis amplitude should be constant. X-axis need to be varied with bars of various width...
