Upgradation issues with Exporting charts to JPG/PNG

[allareddy123]

Hi,

We are trying to upgrade Fusion charts to XT version. Previously we were using Flash based charts and JSP based exporting feature.

We are upgrading to latest version to get the context menu for downloading the charts as image/PDF. We have followed  all the steps and upgradation went successfully. But we are getting issues with export feature.

 

Issues we found

1. JAR files are not cmpatible with JSP files (FCExporter.jsp/FCExporter_PDF.jsp etc) not compiling becuase of classes which are in JAR are not in consistent with JSPs.

        a) com.fusioncharts.exporter.ErrorHandler has been chnaged to com.fusioncharts.exporter.error.ErrorHandler

        com.fusioncharts.exporter.FusionChartsExportHelper have some constants which are not present in newer version.

 

2. Is JAVAScirpt based charts can be exported using jsps similar to Flash based charts? Right now, our both flash based or java script based charts are not downloading becuase of #1 issue.

3. Flash based charts are not working at all.

 

P.S we are using licensed version

 

Please let me know if you need any more details required for the same.

Hi,

 

Welcome to FusionCharts Forum 

 

It seems that you are using a JavaScript chart and are trying to export it like you export a Flash chart. The jars "fcexporter.jar" , "fcexporthandler.jar" and "fchelper.jar" are used to export Flash charts.

 

Charts rendered in JavaScript support only server-side exporting. There are two ways to export JavaScript charts at servers-side :

 

1. Using "export.api3.fusioncharts.com" in which case it connects to external servers to export the chart. User must have an active internet connection for this feature to work.

 

For using external servers to export the chart, you need to set the following attributes :

 

Ref.

<chart exportEnabled='1' exportAction='Download' exportAtClient='0' .... >

 

2. Using "Apache Batik SVG Rasterizer library" in which case you can use own server to export the chart

 

For information on exporting using "Apache Batik SVG Rasterizer library", please refer our documentation link : http://docs.fusioncharts.com/charts/contents/exporting-image/ECPureJS.html

 

Hope this helps.

Thanks Haritha for quick reply.

 

Yes, we are trying with JS based export because of context menu feature. But as i mentioned earlier, Our Flash based export (Right click) also not working because of API classes in consistency with JSP files provided as part of up gradation.

Ideally up gradation should provide back ward compatibility of "Exporting Flash based charts" using server side, which is not working for us. Our primary question is why upgraded version of JSPs are not in consistent with API.

One more issue is to download Apache Batik SVG Rasterizer library, http://xmlgraphics.apache.org/batik/download.cgi seems to be down. Is there any other way to get the libraries?

 

Thank you so much for the help.

>>  Could you please let us know the FusionCharts version that you were previously using and the version that you are using now, so that we can investigate on this better?
