Yes, I have tried this in several different examples from your support team, but it does not work as given. The echo outputs from the php in the sample and in my php are both in the correct json format. I can take either echo and render them directly with fusioncharts.
In the provided sample, I get the ajax error message alert. When I use the same method to my application, i do not get the alert, but i also do not render a chart.
The problem must lie in the ajax app, or I am missing something in my js/ folder to allow jquery to work properly. I changed the file paths in the sample to match my file directory.
The database works, and the php query and echo work.
Is there a simple method to test the jquery is working properly?
