How to create area range chart

Question:

I want to create area range chart as given in the following <a href="http://jsfiddle.net/D4w7G/3" rel="nofollow">link</a>

I want to add data to ranges using loop on my data. What should be the type of the ranges to create chart?

Please suggest. Thanks in advance. Here's the JSFiddle code:

Answer1:

Here is an example the produces a Chart graphic just like the one in the linked image.

Note: After I have created a few testdata I calculate a dummy series with a transparent color that will make the whole data stack up so that the median of the "neutral" series sits nicely on one horizontal line.

int numPoints = 30; // create some test data List<int> neutralData = new List<int>(); List<int> negativeData = new List<int>(); List<int> positiveData = new List<int>(); List<int> dummyData = new List<int>(); for (int i = 0; i < numPoints; i++) { // the real data series, using a Random R: positiveData.Add(R.Next(i + 22)); neutralData .Add(R.Next(i + 33)); negativeData.Add(R.Next(i + 44)); // calculate the transparent bottom series: dummyData.Add( - neutralData[i] / 2 - negativeData[i]); } // set up the Chart: chart1.ChartAreas.Add("StackedArea"); // if necessary Series s0 = chart1.Series.Add(" "); Series s1 = chart1.Series.Add("negative"); Series s2 = chart1.Series.Add("neutral"); Series s3 = chart1.Series.Add("positive"); foreach (Series s in chart1.Series) s.ChartType = SeriesChartType.StackedArea; s0.Color = Color.Transparent; s1.Color = Color.FromArgb(200, Color.Red); s2.Color = Color.FromArgb(200, Color.LightSlateGray); s3.Color = Color.FromArgb(200, Color.Green) // now add the data points: for (int i = 0; i < numPoints; i++) { s0.Points.AddXY(i, dummyData[i]); s1.Points.AddXY(i, negativeData[i] ); s2.Points.AddXY(i, neutralData [i]); s3.Points.AddXY(i, positiveData[i]); }

If you want to show a tooltip similar to the one from your example you can add this to the AddXY loop:

int a2 = dummyData[i] + negativeData[i]; int a3 = a2 + neutralData[i]; int a4 = a3 + positiveData[i]; string tt = string.Format( "Data Point {0}\r\nPositive: {1} - {2}\r\n" + "Neutral: {2} - {3}\r\nNegative: {3} - {4}", i, a4, a3, a2, dummyData[i]); s1.Points[i].ToolTip = tt; s2.Points[i].ToolTip = tt; s3.Points[i].ToolTip = tt;

Here is an example image: <img alt="StackedArea Chart with Tooltip" class="b-lazy" data-src="https://i.stack.imgur.com/66kEb.png" data-original="https://i.stack.imgur.com/66kEb.png" src="https://etrip.eimg.top/images/2019/05/07/timg.gif" />

Answer2:

You can not create a chart exactly like the one shown in link but you can use different series on your chart. I am posting the code that creates a chart and populates it with 2 series, you can add as many series as you want.

DataSet dataSet; ConnectionClass.GetInstance().connection_string = Properties.Settings.Default.MindMuscleConnectionString; ConnectionClass.GetInstance().Sql = "Select Count(MemberInfo.memberName) as 'Members', CompetitionName as 'Competition' FROM MemberInfo, MemberBodyInfo, Competition WHERE MemberInfo.memberID = MemberBodyInfo.memberID AND MemberBodyInfo.weight >= Competition.CompetitionCategory and MemberBodyInfo.weight <= Competition.CompetitionCategory + 5 group by CompetitionName;"; dataSet = ConnectionClass.GetInstance().GetConnection; chart1.Series["Series1"].Name = "Members"; chart1.Series["Members"].YValueMembers = "Members"; chart1.Series["Members"].XValueMember = "Competition"; chart1.Series.Add("Members2"); chart1.Series["Members2"].ChartType = SeriesChartType.StackedArea; chart1.Series["Members2"].IsValueShownAsLabel = true; chart1.Series["Members2"].YValueMembers = "Members"; chart1.Series["Members2"].XValueMember = "Competition"; this.chart1.Titles.Add("Competition Participants"); // Set the chart title chart1.Series["Members"].ChartType = SeriesChartType.StackedArea; chart1.Series["Members"].IsValueShownAsLabel = true; // To show chart value chart1.DataSource = dataSet; chart1.DataBind();

I have not actually created a new series from some different data... Both series are same here but I have just showed you an example.
