Refreshing data dynamically

Hi,

I have a simple question related to the way I could refresh data of a serie dynamically.

Suppose I have a thread that receive an array of double a few times per second. The size of the array is for example 1000. What is the best and fastest way to refresh my serie and make sure I will see all arrays in my chart and make sure that the Eclipse IDE won't be freeze by the thread and by the update of the chart?

I made the following example, but I have several problem with it.
1- The updates freeze the IDE
2- The refresh of the serie is pretty slow
3- The update of the chart starts only at the end of the processing of the array. If i replace the for loop by a infite loop, the UI is freeze infititely
4- Make sure the IDE have enough cpu to continue to work.

You can answer me at the following address:

Example (based on LargeSeriesExample.java):

public class SampleView extends ViewPart {

public SampleView() {
}

public void createPartControl(Composite parent) {

final Chart chart = new Chart(parent, SWT.NONE);

chart.getTitle().setText("Large Series Example");
chart.getAxisSet().getXAxis(0).getTitle().setText("Data Points");
chart.getAxisSet().getYAxis(0).getTitle().setText("Amplitude");

final ILineSeries lineSeries = (ILineSeries) chart.getSeriesSet().createSeries(SeriesType.LINE, "line series1");

lineSeries.setSymbolType(PlotSymbolType.NONE);
lineSeries.setYSeries(getSeries(0, i));

// adjust the axis range
chart.getAxisSet().adjustRange();

parent.getShell().getDisplay().asyncExec(new Runnable() {
@Override
public void run() {
for (int t=0; t< 100; t++) {
lineSeries.setYSeries(getSeries((double)t, 0));
chart.redraw();
chart.update();
}
}
}
);
}

private static double[] getSeries(double t, double y) {
double[] series = new double[1000];
for (int i = 0; i < series.length; i++) {
series[i] = y + Math.sin(t + i * 33 * Math.PI/ series.length) + Math.sin(t + i * 15 * Math.PI/ series.length);
}
return series;
}
