I am using the XamGeographicControl. I load a series of about 8000 points and have a DataTrigger to map or hide select points based on a binary flag found in each point.
As i set the flag for points, some of them appear and others do not.
Now, without changing the flags, if i zoom then some points seems to disappear and reappear as i zoom the map.
I am wondering if there is something going on within the control to perhaps optimize the data in some way, that results in this.
For example perhaps if there are two points in the same place, could the points i wish to see but cannot - perhaps they are optimized out - while another point i wish to hide is over top.
It seems random which points are shown. Maybe when points are close together the control drops one?
Hi OttawaDeveloper,
Each series inherits a property called Resolution from the base Series class. http://help.infragistics.com/NetAdvantage/WPF/2013.1/CLR4.0/?page=InfragisticsWPF4.Controls.Charts.XamDataChart.v13.1~Infragistics.Controls.Charts.Series~Resolution.html
You can try setting this to 0 to see if that makes a difference. It may depend on what type of series you are actually using. Can you let me know which series you are using in the XamGeographicMap?
Well i tried that and it seems to be worse - i got nothing.
Why is the documentation for 'resolution' not giving any information about what the numbers mean. All it tells me is that it is a double. It does not give a range or meaning to the numbers here. I tried 1000000 and it seems to be about like it was before.
You used VS 2012, i have only VS2010. Trying to look at sample anyhow.
Here is an updated sample for VS2010.
Thanks, got bumped onto another priority for a short time, will come back to this.
