Q:

androidplot - how can I empty SimpleXYSeries

i presume it is pretty basic, but I can't find the solution.
I have something like this:
public SimpleXYSeries historySeries;
historySeries = new SimpleXYSeries("something");

then in background thread I add some data to the series:
historySeries.addLast(newRoll, newAzimuth);

Question is, how can I easily just remove all the data entries from the series, when needed?
Right now I have something like:
public void initSeries() {
        historyPlot.removeSeries(historySeries);
        historySeries = null;
        historyPlot.clear();
        historySeries = new SimpleXYSeries("something");
        historyPlot.addSeries(historySeries, lpf);
    }

It works, but graph flickers when I do addSeries again.
EDIT:
I have resolved the issue by making my own version of SimpleXYSeries and added a method:
    public void removeXY() {
        lock.writeLock().lock();
        try {
            xVals.clear();
            yVals.clear();
        } finally {
            lock.writeLock().unlock();
        }
    }

A:

I have always used clear() to remove the plot and never had the graph flicker. Are you trying this on just an emulator or also on a real device?
I also found these method:
historyPlot.getSeriesSet.removeAll(historySeries);
historyPlot.removeMarkers();

I am not sure if it will be any better for a flicker
