AchartEngine 在多條折現更新時 出現數組越界問題的原因

  轉載自http://mobile.51cto.com/design-447554.htm

總結出現這個問題的原因是因爲在每次更新MXyMulipleSeriesDataset時候需要先清除掉它中的series 然後再更新series 再把series添加到 mXYMulipleSeriesDataset 中， 否則則被認爲是在後面添加。 就會造成數組越界

int serLen = mXYMultipleSeriesDataset.getSeriesCount();
for (int i = 0; i < serLen; i++) {
TimeSeries series = (TimeSeries)mXYMultipleSeriesDataset.getSeriesAt(i);
mXYMultipleSeriesDataset.removeSeries(series);
for (int j = 0; j < singleF.length; j++) {
series.add(XDList.get(i)[j], yFList.get(i)[j]);
}
mXYMultipleSeriesDataset.addSeries(i, series);
}


int dLen = XDList.get(0).length;
mXYMultipleSeriesRenderer.setXAxisMax(XDList.get(0)[dLen - 1].getTime());
mXYMultipleSeriesRenderer.setXAxisMin(XDList.get(0)[0].getTime());
mGraphicalView.repaint();
}
