how to display total sum of a pie chart using fusion chart in asp

[Chaucer]

is there a way to to show the total sum of pie chart using fusion chart? I have created fusion charts in ASP and all what i am trying to do is to show the total sum values of all the slices of the pie chart. For instance, if i have 3 slices on my pie chart: and each one has these values: 20, 30, 25; so i want to show the total 75 in the sub caption area or on the top of the chart. Is there a way to do this? please help. \[code\] public string CreateChart() { SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString); string sqlStatement = "SELECT Category, AvgNumbers FROM MyTable"; SqlCommand cmd = new SqlCommand(sqlStatement, con); con.Open(); SqlDataReader reader = cmd.ExecuteReader(); string strXML; strXML = "<graph caption='Average Days To Close' subcaption='I want to show here the Total Sum' labelDisplay='auto' useEllipsesWhenOverflow='1' decimalPrecision='0' showValues='1' enablesmartlabels='0' showlabels='0' legendAllowDrag='1' numberSuffix=' Days' showLegend='1' pieSliceDepth='45' formatNumberScale='0'>"; while (reader.Read()) { strXML += "<set name='" + reader["Category"].ToString() + "' value='" + reader["AvgNumbers"].ToString() + "' />"; } strXML += "</graph>"; return FusionCharts.RenderChart("/FusionCharts/Pie3D.swf", "ChartID", strXML, "FactorySum", "450", "450", false, false); }\[/code\]
