I have this situation:

I what to create this chart https://lvcharts.net/App/examples/v1/wf/Stacked%20Area from an info of datagridview, that is not the problem, the problem is that i want to create the chart just using 2 variables, date and value.

Now that i had already charge the datagridview with the info, i proceed to create the chart on this way:

private void crearGrafica5()
 
 int con = 0;
 foreach (DataGridViewRow row in dataGridView3.Rows)
 
 con++;
 

 if (con > 0)
 
 Func<ChartPoint, string> labelPoint = chartPoint =>
 string.Format("0 (1:P)", chartPoint.Y, chartPoint.Participation);

 int conn = 0;
 string utilidades = new string[dataGridView3.RowCount];
 string fechas = new string[dataGridView3.RowCount];

 cartesianChart2.Series.Clear();
 cartesianChart2.Series = new SeriesCollection ;

 foreach (DataGridViewRow row in dataGridView3.Rows)
 
 utilidades[conn] = row.Cells[3].Value.ToString();
 fechas[conn] = row.Cells[3].Value.ToString();
 conn++;
 

 string values_grafica = "new ChartValues<DateTimePoint> ";

 for(int i=0;i<utilidades.Length;i++)
 
 if (i == 0)
 
 values_grafica += "new DateTimePoint(new System.DateTime(" + fechas[i] + "," + utilidades + ")";
 
 else
 
 values_grafica += ",new DateTimePoint(new System.DateTime(" + fechas[i] + "," + utilidades + ")";
 
 

 values_grafica = "";

 ChartValues values_gra = new ChartValues<>;

 if (conn < 10)
 
 cartesianChart2.Series.Add
 (
 new StackedAreaSeries
 
 Title = row.Cells[0].Value.ToString(),
 Values = /////this is my problem,
 LineSmoothness = 0
 
 );
 
 conn++;


 pieChart1.LegendLocation = LegendLocation.Bottom;
 button1.Enabled = true;
 
 else
 
 button1.Enabled = false;
 pieChart1.Series.Clear();
 
 

But i don't know how can i add the values_grafica string to the values of the chart.

Please any help?
