TimeSeries Questions

[newbie]

Hi,
I am trying to draw multiple Range axis TimeSeries graph.
I am using the ChartFactory.createTimeSeriesChart(...) method and adding the multiple axis by something like:

XYPlot plot = chart.getXYPlot();
plot.setRangeAxis(1, axis2);
plot.setDataset(1, dataset);

All this seems to be working fine and I am able to see my chart being drawn nicely. But I have a few problems that I am not able to solve:
1. What is the maximum number of Range axis that I can add to the graph?
2. I want to show 10 Minutes of data at one time. so I used the following method:
axis.setFixedAutoRange(10*1000*60); // millis
This works but domain axis shows the ticks from the (current time - 10 ) minutes to current time . How can I get it to draw starting from the from the current time to current time+10 instead.


Any help is appreciated.
Regards...

1. What is the maximum number of Range axis that I can add to the graph?

There is no limit, except the available space to draw the axes and the ability of the reader to decipher what it all means.

2. I want to show 10 Minutes of data at one time. so I used the following method:
axis.setFixedAutoRange(10*1000*60); // millis
This works but domain axis shows the ticks from the (current time - 10 ) minutes to current time . How can I get it to draw starting from the from the current time to current time+10 instead.

Do you mean initially when there is less than 10 minutes worth of data? I don't know a good way to make that work, yet, but I agree that it would be nicer than what JFreeChart does now.
