                            chart +i+ .Series.Add(thisReader.GetValue(0).ToString());
                            i++;

    Use an array of charts :

    Code:
    int numberOfCharts = 10;
    Chart [] charts = new Chart[numberOfCharts];
    
    // you need to populate them
    for (int index = 0; index < numberOfCharts; ++index)
    {
        charts[index] = GetChart(index);
    }
    
    while (thisReader.Read())
    {
        chart[i] .Series.Add(thisReader.GetValue(0).ToString());
        i++;                                                
    }
    If you already have chart1, chart2 etc defined (e.g. in a UI) then you can set the items of the chart array manually e.g.

    Code:
    int numberOfCharts = 10;
    Chart [] charts = new Chart[numberOfCharts];
    chart[0] = this.chart1;
    chart[1] = this.chart2;
    chart[2] = this.chart3;
    // etc

    EDIT:

    Code:

        Chart[] charts = new Chart[5];
                        charts[1] = chart1;
                        charts[2] = chart2;
                        charts[3] = chart3;
                        charts[4] = chart4;
                        charts[5] = chart5;
