hi all,

I have a datatable which consists of many datarows with columns: CUSTOMER, MAX, MIN, AVG, 25TH_PERCENTILE, 50TH_PERCENTILE AND 75TH_PERCENTILE. I also have a foreach loop which will loop through each row of datatable and assign each datarow data into each series of the chart to plot the chart.

I am able to loop through average value in each row of datatable. But now I faced with other issues..

Question: How can I loop through the average value of each point being added to the series of the chart? (Please look at my code below: )

This is my code:

C#

int avg=0;         

foreach (DataRow row in dt.Rows)
                        {
                            Chart1.Series[0].Points.AddXY(row["CUSTOMER"], new object[] { row["MIN"], row["MAX"],
                            row["25TH_PERCENTILE"], row["75TH_PERCENTILE"], row["AVG"], row["50TH_PERCENTILE"] });

                            Chart1.Series[1].Points.AddXY(row["CUSTOMER"], new object[] { row["AVG"] }); 


                            if (!String.IsNullOrEmpty(row["AVG"].ToString()))
                            {
                                avg = Convert.ToInt32(row["AVG"].ToString());
                            }

                            if (avg >= 0 && avg <= 10)
                            {
                                Chart1.Series[1].MarkerColor = Color.Green;
                            }
                            else if (avg >= 11 && avg <= 30)
                            {
                                Chart1.Series[1].MarkerColor = Color.Yellow;
                            }
                            else if (avg >= 31 && avg <= 50)
                            {
                                Chart1.Series[1].MarkerColor = Color.Red;
                            }
                        }

This is the output I get currently:

Solution 1

C#

if(int.Parse(row[Avg].ToString()) >=1 && int.Parse(row[Avg].ToString()) >=5)
{             
    Chart1.Series[1].MarkerColor = Color.Blue;
}
else if(int.Parse(row[Avg].ToString()) >=6 && int.Parse(row[Avg].ToString()) >=10)
{
    Chart1.Series[1].MarkerColor = Color.Yellow;
}
else
{
    Chart1.Series[1].MarkerColor=Color.Green;
}

hi KR, thanks for your help! :) But I encountered some issues here.. your solution is for the whole series of the chart, how can I loop through the average value of each point being added to the series of the chart?

For example: Chart1.Series[1].Points.AddXY(row["CUSTOMER"], new object[] { row["Avg"] }); , I want to check what are the average value for each point added on the series, I want to loop through the average value for each point added on the series of the chart. Let's say there are 3 points on the series of the chart, I want to loop through the average value of each point on the series of the chart. Please take a look at my updated post, thanks!

Solution 2

Since you are already inside the foreach loop, you can do something like:

C#

var average = (int)row["Avg"];
if ((average >= 1) && (average <= 5))
{
	Chart1.Series[1].MarkerColor = Color.Blue;
}
else if ((average >= 6) && (average <= 10))
{
	Chart1.Series[1].MarkerColor = Color.Yellow;
}
else
{
	Chart1.Series[1].MarkerColor = Color.Green;
}

may help you:

C#

foreach (DataRow row in dt.Rows)
    {
       Chart1.Series[0].Points.AddXY(row["CUSTOMER"], new object[] { row["MIN"], row["MAX"],
       row["25TH_PERCENTILE"], row["75TH_PERCENTILE"], row["AVG"], row["50TH_PERCENTILE"] });

       Chart1.Series[1].Points.AddXY(row["CUSTOMER"], new object[] { row["Avg"] });
       int avg = 0;
       if(!String.IsNullOrEmpty(row["Avg"].ToString()))
         {
             avg = Covert.ToInt16(row["Avg"].ToString());
         }

       if(avg >=1 && avg <=5)
          {
            Chart1.Series[1].MarkerColor = Color.Blue;
          }
       else if(avg >=6 && avg <=10)
          {
            Chart1.Series[1].MarkerColor = Color.Yellow;
          }
        else
          {
            Chart1.Series[1].MarkerColor=Color.Green;
          }
    }
