Range(double, double): require lower (Infinity) <= ...

[cmose]

Hello again,
I've got a stackedxyareachart based on a timetablexydataset. When the timetablexydataset is populated with only 0 value tasks, I receive the following exception from the chart:

Code: Select all

java.lang.IllegalArgumentException raised:
Range(double, double): require lower (Infinity) <= upper (-Infinity).

any suggestions as to what might be the problem here?
Thanks much.

It sounds like you've triggered a bug. I'll try to reproduce it, but if you can supply a small self-contained demo that shows the problem, that will help a lot.

david thanks for the info. Unfortunately my code is on a development network without internet access and I don't fancy hand typing all that over. I'll hop back on in a few though and type in the relevant (at least, what I believe to be relevant given my limited understanding of the library) bits.

I get the same exception in an XYPlot. The plot object is created with a null dataset (no problem doing that according to the API...). Then later, I try to set the max and min values of the date axis to constant values (ie, 0900h and 1830h) and I get the exception:

Code: Select all

java.lang.IllegalArgumentException: Range(double, double): require lower (1.17285432E12) <= upper (1.172853E12).

	at swx.eservices.chart.ChartReader.createChart(ChartReader.java:561)
	at swx.eservices.chart.ChartReader.generate(ChartReader.java:313)

I will try to reproduce this in the demo code and post an example...

whoops, been out sick so didn't get a chance to pop back on here....
I think I had been setting a max range but there was never a null dataset. The dataset was always 0 filled in the event that there was no data (have a line chart based on the same dataset and that works fine).

It's late but I'll try to print out the creation of the dataset and the chart and transcribe them here in a bit. Have to get settled in for the morning yet

[cmose]

ok, here are the relevant bits of code.

where I create the chart:

Code: Select all

NumberAxis yAxis = new NumberAxis("Bytes");
DateAxis dateAxis = new DateAxis("Hour");
TimeTableXYDataset ttd = (TimeTableXYDataset)data;
dateAxis.setTickUnit(new DateTickUnit(DateTickUnit.HOUR), 1));
XYPlot plot = new XYPlot(ttd, dateAxis, yAxis, new StackedXYAreaRenderer2());
JFreeChart chart = new JFreeChart(plot);

where I populate the dataset:

Code: Select all

TimeTableXYDataset ttd = new TimeTableXYDataset();
...
//fetch data from database grouped by hour
//loop through last 24 hours, if there is data for a given hour:
if(data for given hour){
   ttd.add(new Hour(tempDate), type.getTotalBytes(), type.getType());
}else{//if no data for that hour
   for(String s : Series){
      ttd.add(new Hour(tempDate), 0f, s);
   }
}

bascially all I'm doing is populating the dataset if there is data from the database. If there isn't any data from the database, I 0 fill the dataset for each hour of the last 24, setting a 0 value for each series. I've verified that a null dataset is not being returned...

The bug is still present in 1.0.5. To reproduce it, apply the patch below to jfreechart-1.0.5-demo/source/demo/TimeSeriesDemo1.java then recompile and run the demo. You will get the IllegalArgumentException...

Basically, you remove all the data points in the createDataset method (nothing wrong with that...) then try to setMinimumDate/setMaximumDate in the createChart method.[/code]

Thanks for the steps to reproduce. Be careful when you use that deprecated java.util.Date constructor - the year argument must be supplied as 'year - 1900' (that is, 107 if you want 2007). Still, it reproduces the bug either way. For the next release (1.0.6) I'll make the setMaximumDate() and setMinimumDate() methods check to see where the new bound is relative to the opposite bound on the axis, and adjust if necessary.

[oscar]

Thanks for having a look at this buglet... I await 1.0.6 with anticipation!

Rgds,
Oscar

I took your tips on how to avoid the exception and implemented them on our server. I submitted the patch to DataAxis.java on sourceforge (see https://sourceforge.net/tracker/index.p ... tid=315494)

[david.gilbert]

Here is the patch I already applied:
