UltraGeographicMap Zoom to GeographicSymbolSeries
posted

I'm trying to use the ultraGeographicMap. I'm plotting points, as follows:

            var series = new GeographicSymbolSeries();
            series.LongitudeMemberPath = "X";
            series.LatitudeMemberPath = "Y";
            var geoLocations = new List<Infragistics.Win.DataVisualization.Point>();

            foreach (var point in route)
            {
                geoLocations.Add(new Infragistics.Win.DataVisualization.Point() { X = point.Geocode.DoubleLongitude, Y = point.Geocode.DoubleLatitude });
            }

            series.DataSource = geoLocations;
            this.ultraGeographicMap1.Series.Add(series);

            var geoRegion = new Infragistics.Win.DataVisualization.Rectangle(route.FirstOrDefault().Geocode.DoubleLongitude, route.FirstOrDefault().Geocode.DoubleLatitude, 30, 20);
            this.ultraGeographicMap1.WindowRect = this.ultraGeographicMap1.GetZoomFromGeographic(geoRegion);

Is there a way to zoom to the GeographicSymbolSeries that is being plotted?

Thanks,

    Hello James,

    Thank you for posing. Unfortunately, there is no zoom to functionality when it comes to a series. If you are manually providing points to the series then you should be able to calculate the min/max longitude and latitude from all those points and with the min/max you can update the maps WindowRect to encompass that rectangle , which is you you already doing and your code is looking correct to me .

    Try some like this:

    // calculate the min/max longitude and latitudes 
var minLongitude = GetMinLongitude();
var maxLongitude = GetMaxLongitude();
var minLatitude = GetMinLatitude();
var maxLatitude = GetMaxLatitude();

// use the GetZoomFromGeographic method to generate a new WindowRect
var rect = this.geoMap.GetZoomFromGeographic(new Point(minLongitude, minLatitude), new Point(maxLongitude, maxLatitude));
this.geoMap.WindowRect = rect;

    if this dosent work please share your sample to investigate it further.
