  1. Hi, We have an ASP.NET application that has fusion charts on different pages and the application has a pdf report generation fuctionality. The user can export the charts (server side) and can add it to a queue to add it to the PDF report. We have a load balancing environment. Now the issue is... If the user exports images from different pages (say around ten images) and add them to the queue. few images are getting saved on Server A and few on Server B. Hence while generating the PDF report few images go missing. Is there a solution to handle this scenario? Please advise Cheiro

  4. Invalid Xml Error

    Cheiro posted a topic in FusionCharts and ASP

    Hi We have the following XML that renders chart perfectly in local build. But when it is deployed on the server in IIS, It shows "Invalid XML Error" If we refresh the page after a couple of times the same XML Chart renders just fine. Below XML is from the Log which was captured from the server, same XML gave the error and also rendered fine after refreshes. When the debug more is set as on we get the message as -Start and end tag mismatch But if we check the xml we see that it is well formed. <chart exportEnabled='1' exportAction='Save' exportAtClient='0' exportHandler='../Export_Handler/FCExporter.aspx' showBorder='0' bgAlpha='0,0' baseFont='Arial' baseFontSize='11' labelDisplay='ROTATE' slantLabels='1' showShadow='0' showNames='1' animation='0' showLegend='1' rotateNames='1' showvalues='0' SYAxisName='Filter Hits' PYAxisName='Unique IPs' caption='Failures'> <categories> <category name='2010-1-1'/> <category name='2010-1-2'/> <category name='2010-1-3'/> <category name='2010-1-4'/> <category name='2010-1-5'/> </categories> <dataset alpha='90' color='BBFFBB' showValues='0' parentYAxis='P' seriesname='IPs'> <set value='0'/> <set value='56'/> <set value='78'/> <set value='41'/> <set value='525'/> </dataset> <dataset alpha='90' color='BBBBFF' showValues='0' parentYAxis='P' seriesname='Dest IPs'> <set value='0'/> <set value='110'/> <set value='135'/> <set value='41'/> <set value='642'/> </dataset> <dataset color='FF3333' showValues='0' anchorSides='8' parentYAxis='S' lineThickness='3' seriesname='Hits' anchorRadius='3'> <set value='0'/> <set value='98064'/> <set value='481958'/> <set value='171925'/> <set value='1969662'/> </dataset> </chart> Could anyone advise on this???

    Hi Angshu, Thanks, Chart render : Flash we are using FusionChart.Renderchart() method with SWF Version: Current Version: FusionCharts v3.2.1 (Released on 6th October 2010) Chart Types: ../FusionCharts/MSCombiDY2D.swf ../FusionCharts/MSLine.swf After the deployment, This happens only for the first few times and after several refershes. with the same XML it renders the chart fine.
  6. Hi, Sometimes when there is no data, the chart shows "no Data to display" still the export of chart works and it gives a blank image. is there a way to check if the chart has given " no data to display" error and stop export? Regards, Cheiro

  7. "no Data To Display" Still Exports

    Cheiro replied to Cheiro's topic in FusionCharts and ASP

    Hi, Please find the attached screen shots of chart export and code... the page renders chart using below here the xml has no data... intentionally protected void Page_Load(object sender, EventArgs e) { Literal1.Text = FusionCharts.RenderChart("../FusionCharts/Column3D.swf", "../FusionCharts/SaveDataEmpty.xml", "", "myFirst", "600", "300", false, true); } The xml is like so... the data inside is intentionally commented to simulate no data <chart exportEnabled='1' exportAction='Save' exportAtClient='0' exportHandler='../Export_Handler/FCExporter.aspx' caption='Monthly Unit Sales' xAxisName='Month' yAxisName='Units' showValues='0' formatNumberScale='0' showBorder='1' > <!--<set label='Jan' value='462' /> <set label='Feb' value='857' /> <set label='Mar' value='671' /> <set label='Apr' value='494' /> <set label='May' value='761' /> <set label='Jun' value='960' /> <set label='Jul' value='629' /> <set label='Aug' value='622' /> <set label='Sep' value='376' /> <set label='Oct' value='494' /> <set label='Nov' value='761' /> <set label='Dec' value='960' />--> </chart> Even if the chart shows no data, it allows it to export which results in generation of a blank image.
  8. Hi, I am trying to export fusion chart serverside using javascript to initiate the export. The chart to be exported resides on say Deatils.aspx page. The chart is rendered by using the following code FusionCharts.RenderChartHTML("../FusionCharts/MSCombiDY2D.swf", _url, "", "details_chart", "730", "350", false); where _url is GenerateGraph.aspx, this page renders the graph asynchronously i.e the parent page Details.aspx will continue to render other objects while the chart is loaded paralelly. Now to export the chart the user clicks a link button, on its "OnClientClick", the following javascript function is called which resides on the Details.aspx page // this function exports chart function exportChart(exportFormat) { if (FusionCharts("details_chart").exportChart) { document.getElementById("linkToExportedFile").innerHTML = "Exporting..."; FusionCharts("details_chart").exportChart({ "exportFormat": exportFormat }); } else { document.getElementById("linkToExportedFile").innerHTML = "Please wait till the chart completes rendering..."; } } but the above javascript function throws an error saying that it could not find the "details_chart" object, quite understandably as the whole chart rendering is being taken by GenerateGraph.aspx. In the above scenario how do i do i export the graph??? Is there a way or workaround to get the chart object and javascript exports normally?. I will not be able to render the graph on the Details.aspx itself, (which would solve the problem), as it will block the whole page's loading until graph renders and it is totally unacceptable from user's perspective. Awaiting advice and solutions from you guys. Thanks, Cheiro
