Isolated area in the map

MapWinGIS
1

I have these files:
.cpg
.dbf
.prg
.shp
.shx

And this is the output of the program when I load .shp file:

If you see the center of the map, some of part is isolated with color.
What is the cause of the isolation area?

Thank You

Hello Kayumiy.

Iā€™m not sure if I understand what you are asking. From what I see, it looks like you have loaded 2 layers.

One is a polygon layer, being something like counties or districts. It is sort of a pink-ish salmon color.
The second looks like it might be a road centerline layer, being a gray color.

When a layer is loaded without having a specifically assigned color, it is given a randomly assigned color.

Is there something more you are asking about or concerned about? If so, could you post the code you are using to add the layers?

Regards,
Jerry.

//Add first layer to your map
            int intHandler1; //integer index to handle the layer
            //create a new instance for MapWinGIS.Shapefile 
            //MapWinGIS.Shapefile  is a data provider for ESRI Shapefile
            MapWinGIS.Shapefile shapefile1 = new MapWinGIS.Shapefile();
            //Define the data source for MapWinGIS.Shapefile instance
            shapefile1.Open(@"C:\Users\User\Downloads\Telegram Desktop\AL_11_D002_20200502\AL_11_D002_20200502.shp", null );                   
            //display the layer on the map
            intHandler1 = axMap1.AddLayer(shapefile1, true);

Do you still have this question or did you figure it out on your own?
