Random random = new Random();
Dictionary<string, double> values = new Dictionary<string, double>();
values["MX"] = random.Next(0, 100);
values["CA"] = random.Next(0, 100);
values["US"] = random.Next(0, 100);
values["IN"] = random.Next(0, 100);
values["CN"] = random.Next(0, 100);
values["JP"] = random.Next(0, 100);
values["BR"] = random.Next(0, 100);
values["DE"] = random.Next(0, 100);
values["FR"] = random.Next(0, 100);
values["GB"] = random.Next(0, 100);
geoMap.HeatMap = values;
geoMap.Source = $"{Application.StartupPath}\\World.xml";
this.Controls.Add(geoMap);
geoMap.Dock = DockStyle.Fill;
}You need to download sample data from GitHub: Link
You can find many countries maps in Live-Charts/Live-Maps/tree/master/Maps.
After downloading sample data, you need to copy the World.xml to your project and don't forget set the Copy to Output Directory property of your World.xml file to Copy always.
To play the demo, You should create a dictionary to help you random data for geo chart.
Next, We will define the "key" and number pattern, where the key is the ID of the element in the XML where you want to define the numeric value.
Finally, We will fill the specific keys of the countries with a random number.
Through this c# example you will learn how to use live chart winform to display maps. This is a simple live chart demo how to use GeoMap control to display your maps in c# windows forms application.
