Charting missing values in Time Series

Post by Anthony Berglas » Wed Apr 24, 2002 8:16 pm

Hello,

We are using JFreechart to produce a simple timeseries line chart. However, sometimes there are missing values. We would like to have the connecting line suppressed for missing values rather than just interpolate.

The following link demonstrates the sort of thing we need.

Thanks for your help and for providing such a good package.

There is a demo application in 0.8.1 (com.jrefinery.chart.demo.TimeSeriesDemo) that shows how null values are handled.

Regards,

DG
