Problem with XYLineChart

Jane · Post by **Jane** » Wed Jun 25, 2008 7:23 pm

It seems to me that when the XYLineChart was used to create plots, the data was
sorted with increasing X values. I need to plot in a sequence of increasing Y values.
How do I achieve that?

Thanks,

Jane

It is the dataset class that is sorting by x-value. There is an option in the constructor to enable/disable this.

Thank you very much for your reply.

I am very new here. I looked around in the guide and was only able to find
getDomainOrder with the interface XYDataset on page 809. Could you PLEASE give me
an example showing how to disable the sorting?

Thanks in advance.

I am making a guess that you are using the XYSeries class (and XYSeriesCollection). It has this constructor that you can use when you create the series:

Code: Select all

public XYSeries(java.lang.Comparable key, boolean autoSort);

You need to pass 'false' for the 'autoSort' argument.
