JFreeChart Horizontal Charts

Question

I'm using CombinedDomainXYPlot to plot the charts. I have another requirement where, I need to show the two charts horizontally.

Currently i'm having only one chart. what i need is, i need two charts in the first row. like Chart1 Chart2

Code:

CombinedDomainXYPlot plot = new CombinedDomainXYPlot();
plot.add(getChart1(), 2);
plot.add(getChart2(), 2);

It is giving only one chart in the first row. and second chart2 in the another row.

Is there any way I can make these two charts into single row?

Edit: Actually I wanted it like your ThermometerDemo example. For that you have used JPanel, but here I'm using JFrame.

Please edit your question to include an [sscce](http://sscce.org/), for [example](http://stackoverflow.com/a/11895709/230513). — trashgod, Nov 27 '13 at 05:58
Hi, i don't have the rights to display the screen shot, so only added that two contents. — Mohan, Nov 27 '13 at 06:20
Wanting _two charts into single row_ sounds like you may want `CombinedRangeXYPlot`. — trashgod, Nov 27 '13 at 11:58

I wanted it like your ThermometerDemo example.

Based on this example, the code below adds two panels to a GridLayout(1, 0). Each panel includes it's own chart and control panel.

Thanks.. as like this only i wanted. let me check whether it's suits for me.. thanks a lot — Mohan, Nov 27 '13 at 15:34
