dual y axis plotting causes data points looks messy at left corner of chart

i am using MPAndroid charting toolkit for data visualization. chart plotting smooth in MPAndroid but problem arise when i try plot dual y axis(left& right). As right axis appear data points on spread over the x axis completely. all data points appearing on the left of chart. How can i spread the data points ?

mChart = (LineChart) findViewById(R.id.Chart);
mChart.setGridBackgroundColor(Color.parseColor("#F4F4F4"));
mChart.setDrawGridBackground(false);

mChart.setTouchEnabled(true);
mChart.setHighlightEnabled(false);


mChart.setDragEnabled(false);
mChart.setScaleEnabled(true);
mChart.setPinchZoom(true);
mChart.setDescription("");
mChart.getAxisLeft().setAxisMaxValue(YMaxValue);
mChart.getAxisLeft().setAxisMinValue(YMinValue);
mChart.getAxisLeft().setStartAtZero(false);
mChart.getAxisRight().setEnabled(false);
if(General.InnerClass.Y2AxisValues.size()>0)
{
 mChart.getAxisRight().setEnabled(true);
 mChart.getAxisRight().setSpaceBottom(12.25f);
 mChart.getAxisRight().setAxisMaxValue(Y2MaxValue);
 mChart.getAxisRight().setAxisMinValue(Y2MinValue);
 mChart.getAxisRight().setStartAtZero(false);
 mChart.getXAxis().setAvoidFirstLastClipping(true);
}
mChart.setData(data);
progbar.setVisibility(View.GONE);
mChart.invalidate();

while plotting y2 axis providing the x values is the problem. values for the x axis should be provide for single time. providing twice add the values to x axis exiting values get doubled.

The data points are exactly where they should be. The only thing that has changed is the range of values that is displayed on each axis. --> this range is now significationly lower because only one set of data is represented by each axis, before, one axis had to scale large enough to display both datasets.

I suggest you read the documentation of the YAxis and simply increase the range of values that should be displayed on the axis.
