{
    public List<HeatMapData> HeatMapDataList { get; set; }

    public void OnGet()
    {
        HeatMapDataList = new List<HeatMapData>
        {
            new HeatMapData { Year = "2020", Month = "January", Value = 25 },
            new HeatMapData { Year = "2020", Month = "February", Value = 28 },
            new HeatMapData { Year = "2020", Month = "March", Value = 32 },
            new HeatMapData { Year = "2020", Month = "April", Value = 35 },
            new HeatMapData { Year = "2021", Month = "January", Value = 18 },
            new HeatMapData { Year = "2021", Month = "February", Value = 22 },
            new HeatMapData { Year = "2021", Month = "March", Value = 28 },
            new HeatMapData { Year = "2021", Month = "April", Value = 31 }
        };
    }
}

public class HeatMapData
{
    public string Year { get; set; }
    public string Month { get; set; }
    public int Value { get; set; }
}

Step 2: ~/Pages/Index.cshtml

    <e-heatmap-yaxis labels='new List<string> { "January", "February", "March", "April" }'></e-heatmap-yaxis>
    <e-heatmap-cellsettings showLabel="true"></e-heatmap-cellsettings>
    <e-heatmap-legendsettings type="Gradient"></e-heatmap-legendsettings>
</ejs-heatmap>
