Agreed. It's very well priced as well.
The main drawback of amcharts is that there is no ability to generate
server-side charts (it's all flash, and restricted to client side for
the time being). You'll have to generate charts for pdf's if you need
them using another solution like jfreechart.
Another hiccup we faced was getting them to display - sometimes there
are errors (I forget the reason, but they are intermittent).
You'll have to include swfobject.js as a script, and then the
following code should help:
public void build() {
try {
if (!buildInternal(swfUrl, settingsFile, dataUrl, path,
height,
width < 101 ? width + "%" : width + "",
preloaderColour,
backgroundColour, divID)) {
new Timer() {
public void run() {
build();
}
}.schedule(2000);
}
} catch (final Exception e) {
log(e);
// this happens when the user changes pages before we
have built
}
}
/**
* This calls out to the SWFObject class to build the flash widget
itself
*/
private native boolean buildInternal(String swfUrl, String settings,
String dataUrl, String path, int height, String width,
String preloaderColour, String backgroundColour, String
divID) /*-{
if( typeof($wnd.deconcept) == "undefined" || $wnd.deconcept ==
null ) return false;
var so = new $wnd.deconcept.SWFObject(swfUrl, "amline", width,
height, "8",
backgroundColour);
so.addVariable("path", path);
so.addVariable("chart_settings", escape(settings));
so.addVariable("data_file", escape(dataUrl));
so.addVariable("preloader_color", escape(preloaderColour));
so.addParam("wmode", "transparent");
so.write(divID);
return true;
}-*/;
