I want to have a scatter plot with dates in x-axis.
Because if I use ChartFactory.getTimeChartView I receive a line graph and the problem is:
About scatter type of chart:
Maybe you could just set proper parameters to XYSeriesRenderer:
XYSeriesRenderer r = new XYSeriesRenderer();
r.setColor(Color.GREEN);//green point
r.setPointStyle(PointStyle.CIRCLE);//point in shape of circle
r.setFillPoints(true);//enable points
r.setLineWidth(0);//set line to 0 width - invisible
mRenderer.addSeriesRenderer(r);
and when you are calling factory:
mChartView = ChartFactory.getTimeChartView(this, mDataset, mRenderer,"H:mm:ss");
I'm aware that it is not clean and proper way, but I don't have android here to test it or to figure out more into details...
I didn't test it, so give feed back to me please :).
Hope it helps, Toni
