Q&A ^

• Is is 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.

requirements:

• Fusion Chart 2.3
• swfobject,js

references:

• FusionChart 2.3
• Forum at openlaszlo.org
• SWFObject

example zip: withFusionChart.zip
