[Solved] Change RangeAxis reference and orientation

[Nozalys]

Hello everybody,

I'm searching for changing the way the range axis is drawn, and every topics with keywords "change origin" or "change reference" don't fit to my issue.

What I want to do is the following :



That is to say a bar chart, with the real origin of the bars coming form a value different of zero (-30 for example), but where the Y-range is ordered in increasing order, meaning that the -20 Y-value is upper than the -30 Y-value.

I'v tried to play with following methods without any success :
channelBarChart.getXYPlot().getRangeAxis().setAutoRange()
channelBarChart.getXYPlot().getRangeAxis().setLowerBound()
channelBarChart.getXYPlot().getRangeAxis().setLowerMargin()
channelBarChart.getXYPlot().getRangeAxis().setUpperBound()
channelBarChart.getXYPlot().getRangeAxis().setUpperMargin()
channelBarChart.getXYPlot().getRangeAxis().setInverted()

Is it possible to do what I want ? I guess yes, but didn't find any example... I have everytime the origin of the bars staying at the zero value.

Regards,
Maël

hey,

actually you should have checked the XYBarRenderer. This Renderer has a method which is called "setBase". You can you use it this way.

Code: Select all

    barRenderer.setBase(-30.);

I hope this is what you were looking for.

Thanks a lot Naxter, you solved my headache of the few past days !!

This is exactly what I wanted for, but i did not think to look inside renderer options, only inside the axis options.
