I am using Achart Engine Line chart to display values, i am using point style CIRCLE.
I am trying to implementing the below :
1) Increase the point style width - i mean the circle should be bit bigger.
2) On click of each point i want a popup to be displayed on top of that which will display the values of X and Y.
I have done some research on this but was not able to find the solution.
I found this code but how to display the small popup with values ?
final LineChart chart = new LineChart(buildDataset(mTitles, data), mRenderer);
final GraphicalView view = new GraphicalView(mContext, chart);
view.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
double[] xy = chart.toScreenPoint(view.toRealPoint(0));
int[] location = new int[] {(int) xy[0], (int) xy[1]};
SeriesSelection seriesSelection = view.getCurrentSeriesAndPoint();
if (seriesSelection != null) {
final Data d = mModel.getDiaryAt(seriesSelection.getSeriesIndex(),
seriesSelection.getPointIndex());
//show popup at xy[0] xy[1]
}
}
});
It might have been not given in the SDK but still if anyone has tried this as was successful.
** EDIT **
Link 1 : achartengine toScreenPoint(double) always returns nullPointerException
In the image you can see a popup i want to implement like that.
