We were able to get this figured out. We just had to build the sjsCode as a global variable and add to it for every chart, then call the ScriptManager.RegisterStartupScript once after all of the charts were rendered.

Hi! I'm new to FusionCharts and can't seem to find any information on this subject. I have a web page that I need to render up to 30 small charts on. I have the code working, but it will only render the first chart. It doesn't matter which chart I try to load up first, the next charts do not load. Is there a way to render multiple charts on a single page? My code is below. ChartName, ExportFileName, ChartType, and DivToAddTo are all strings passed in by each chart method that I am loading. I have verified that I am passing in a different div name each time. I also pass in a data set called mainData that I loop through to build the bar string. This is all done in vb.net in the code behind of my page. Dim sbXml As New System.Text.StringBuilder sbXml.Append("<chart caption='" & chartName & "' " & " canvasBorderColor='#ABADB3' " & " canvasBorderThickness='1' " & " xaxisname='' " & " showvalues='1' " & " animation='1' " & " yaxisname='' " & " showBorder='0' " & " bgColor='#ffffff' " & " chartLeftMargin='10' " & " chartTopMargin='10' chartRightMargin='25' " & " chartBottomMargin='20' " & " toolTipBorderColor='#ABADB3' " & " zeroPlaneColor='#f9f9f9' " & " zeroPlaneThickness='1' " & " showAlternateHGridColor='1' " & " forceXAxisValueDecimals='1' " & " forceYAxisValueDecimals='1' " & " forceDecimals='1' " & " showPlotBorder='0' " & " usePlotGradientColor='0' " & " plotHoverEffect='1' plotFillAlpha='100' " & " showShadow ='0' " & " labelDisplay='wrap' " & " numdivlines='5' " & " exportFileName='" & exportFileName & "' exportEnabled ='1' exportAtClient ='0' exportAction ='save' exportShowMenuItem='0' " & " exportHandler ='" & ConfigurationManager.AppSettings.Item("FusionChartsURL") & "'" & " placevaluesInside='1' rotateValues='0' valueFontSize='11'" & " valueFontBold='0' " & " valueFontColor='#ffffff' " & " decimals='1' showLegend='1' legendBgColor='#FFFFFF' legendShadow='0' legendBorderColor='#FFFFFF' paletteColors='#5A3588,##ff9e1b,#ff9e1b'>") For Each item As ContractValue In mainData Dim toolText As String 'set equal to name and value toolText = item.Name & " - " & item.Value 'add category categoryString.Append("<category label ='" & item.Name & "' />") Dim value As Double = 0 Try value = item.Value Catch ex As Exception 'No error, set to blank End Try bar1String.Append("<set value='" & If(value <> 0, value.ToString, String.Empty) & "' color='#ff9e1b' tooltext='" & toolText & "'/>") Next sbXml.Append("<categories>") sbXml.Append(categoryString.ToString) sbXml.Append("</categories>") sbXml.Append("<dataset seriesname='My Average'>") sbXml.Append(bar1String.ToString) sbXml.Append("</dataset>") sbXml.Append("</dataset>") sbXml.Append("</chart>") Dim fusionChart As New Chart(chartType, divToAddTo, "600", "280", "xml", sbXml.ToString) Dim sRenderedChart As String = fusionChart.Render() Dim sStartScriptTag As String = "<script type=""text/javascript"">" Dim sEndScriptTag As String = "</script>" Dim sJsCode As String = sRenderedChart.Substring(sRenderedChart.IndexOf(sStartScriptTag) + sStartScriptTag.Length, sRenderedChart.IndexOf(sEndScriptTag) - sRenderedChart.IndexOf(sStartScriptTag) - sStartScriptTag.Length) & ";" ScriptManager.RegisterStartupScript(Me, Me.GetType, "JSCode", sJsCode, True)
