Unfortunately, engineers are not sure that you can use the OLEContainer with Microsoft Graph. We also unable to find any reference in the web about it.
Here are some suggestions:
– Create your own COM enabled application which display the chart then call it from the Applet.
– Create the chart in other programs (i.e. Excel, word, etc), save to html/image then show it in Formativ Form using the Image or EmbeddedWB control.
Hope this helps.
