Detailed Bug-report: verticalXYBarChart

[BugHunter]

Hello,
I'm using JFreeChart 0.7.4 on Windows NT.

I get a bug when I use verticalXYBarChart:

My code is pretty much like the code from the Demo, the only difference is that I take a day interval instead of a year interval to make the TimeSeries.
Here is where I make the TimeSeriesCollection, reading the data from a MySQL database:

public TimeSeriesCollection readTimeSeriesCollection(String table){
//read the data from the table

BasicTimeSeries ts = new BasicTimeSeries("Dolar", "Day", "Value", Day.class);
try{
System.out.println("Reading chart data");
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);

String dbQuery = "select * from " + table;
ResultSet rs = stmt.executeQuery(dbQuery);

Day day = null;
Double d = null;
int counter = 1;
//copy the resultSet into the BasicTimeSeries:
while(rs.next()){
day = new Day(counter++, 1, 2002);
d = new Double(rs.getDouble(2));
//here is where the data is added to the BasicTimeSeries:
ts.add(day, d);
}
}catch(Exception e){
e.printStackTrace();
}
return new TimeSeriesCollection(ts);
}

After that I take that TimeSeriesCollection and create a Chart with it, like in the demo:

IntervalXYDataset data = ds.readTimeSeriesCollection("timeSeries");
chart = ChartFactory.createVerticalXYBarChart(title, xAxisLabel, yAxisLabel, data, true);

It works, and actually displays a chart. But when the chart is displayed I get these error messages:

This message gets displayed when the chart is first drawn and almost every time I resize it. I noticed that if I resize it to a small chart the exception doesn't happen.

Hope this helps to fix the bug.

Thanks for the report...the detail is good, better than I get for some bug reports!

I don't think the problem is your dataset, it looks like you are creating it correctly. It might be related to another bug report to do with the cross-hairs. Try turning them off and see if you still get the problem...I'll take a closer look at the code, because something needs fixing.

To turn off crosshairs, you need to get a reference to each axis (cast to ValueAxis) and call setCrosshairVisible(false).

P.S The PRException typically shows up when you try to render a shape in Java2D with either very large coordinates or NaN values.
