Q&A

  • Is it possible to use charts to update in realtime on this plugin?
Yes. This plugin includes OpenLaszlo charts components. So you can use them. These components are located in GRAILS_APP/web-app/lps/components/charts. For example please visit http://localhost:8080/GRAILS_APP/lps/components/charts/test/integral/ after running "grails run-app" on your grails application. Also it's available to use Fusion Chart 2.3 on OpenLaszlo plugin. Using withFusionChart.zip, it shows like this: In this example there are two buttons. One is a button to update a chart inside on flash by OpenLaszlo. Another is outside flash by HTML button, which calls Java script function to update same chart object by SWFObject.js. ref. http://localhost:8080/GRAILS_APP/plugins/laszlo-1.0.1/charts/

requirements:

  • Fusion Chart 2.3
  • swfobject,js
