... actually I wasn't even aware that there is another view than NDateTimeAxisPagingView - I just did use copy-paste from the given Nevron examples. Thanks a lot - now it is working much better. But one problem remains. When I have the X-axis as a real time axis - lets say with a time range of several days or even weeks and I zoom into X-Axis, so that only e.g. less than 1 day time range for the chart view remains - than the labeling of the X axis changes from the actual date with day/month (which is good) to hours. To see the hours is also good - but I need to see the date with the day as well. Is there a way to force a time axis label to show always the date as well?

Thanks again,
Best regards,

Hi Joern,

Is there any particular reason why you use NDateTimeAxisPagingView - you should be using NNumericAxisPagingView view which will not perform date / time calculations for the zoomed range. Otherwise the control has been tested with very small ranges and should be working without any problems.

Hope this helps - let us know if the problem persists.

Hi Experts,
I have a problem when using the zoom functionality in a scatter plot with Y-data ranging from -1 ... 1 (equal step size 0.01). As long as the scrollbar is disabled, everything is working well. But when I enable the scrollbar:
//Add Scrollbar for Zoomed Area
_oChart.Axis(StandardAxis.PrimaryX).PagingView = new NDateTimeAxisPagingView();
_oChart.Axis(StandardAxis.PrimaryX).ScrollBar.Visible = true;
_oChart.Axis(StandardAxis.PrimaryY).PagingView = new NDateTimeAxisPagingView();
_oChart.Axis(StandardAxis.PrimaryY).ScrollBar.Visible = true;
then the displayed zoomed Y-area after the zoom has finished is not the range which was selected with the zoom rubber box.
This effect happens mainly for zooming around Y-axis values of 0.

When I change the Y-data to range from -100...100 (with equal step size 1) everything is working.

Is there a workaround to use zoom a n d scrollbar together with smaller Y-data close to zero?

Thanks for your help,
best regards,
Joern
