Hello, I am trying to implement Google charts in a work of mine, I make a project in PHP and SQL with a web interface. Managed to draw a simple line chart with a few options, now i stumbled across event listener thing, It is possible to make an event listener for the legend ? lets say if you click on "Value 1" square in the legend the line will toggle between show/hide ? I can`t get the wrapper to work with the line chart designed, i currently using PHP to get values from SQL and parse it in the JavaScript like this: ... echo 'data.addRow(["'.$timestamp.'", '.$power.', '.$pb2w2.', '. $pb2w3.', '.$pb2w4.', '.$pb1w3.', '.$pb1w1.', '.$pb1w2.']);'; Is it wrong to do so ?
How about progress bar? the graph takes several seconds to load, until then all the page is a little messed up, I need some kind of progress bar (event trigger ? ) to show graph only when is ready. Here I think the wrapper comes in handy. I am just a beginner in JavaScript, any help is welcomed ! -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
