Hi,

I'm having a bit of trouble with NStockSeries and i'm hoping someone can help. I'm trying to figure out how to automatically focus the x axis on a specific range of bars in the chart. This is how I'm populating the chart:

NCartesianChart cartChart = (NCartesianChart)_chart.Charts[0];
NStockSeries stockSeries = (NStockSeries)cartChart.Series[0];

for (int i = stockSeries.XValues.Count; i < _marketData.Bars.Length; ++i)
{
MarketData.Bar bar = _marketData.Bars[i];
stockSeries.AddDataPoint(new NStockDataPoint(bar.Open, bar.High, bar.Low, bar.Close, bar.DateTime));
}


.. And I then try to set the paging view on the x axis to the last 4 months worth of data (_marketData.Bars is already sorted by date).

DateTime endDate = _marketData.Bars.Last().DateTime;
DateTime viewBegin = endDate.AddMonths(-4);
NNumericAxisPagingView dateAxis = new NNumericAxisPagingView(new NRange1DD(viewBegin.ToOADate(), endDate.ToOADate()));
dateAxis.Enabled = true;
cartChart.Axis(StandardAxis.PrimaryX).PagingView = dateAxis;


When I run this the view seems to have scrolled to some date much further in the future than any bar of market data I have, although it's difficult to tell the exact date. I've also tried using the NDateTimeAxisPagingView with similar results.

Another point is when I change the logic to attempt to keep the first 4 months of data in focus, it tends to scroll to somewhere roughy in the middle.

One other question I have is is it possible to discover which bars are in the view after the user zooms + scrolls? This is so that I can set the y axis paging view to the min and max value of the visible bars, in order to zoom the y axis in on what is visible.

Thanks for any help
David.

Hi David,

Yes that works - there were several issues related to the calendar which were fixed in SP1 for 2012 - we used build number 12.5.9.12. What is the version you're currently testing with?
