Hello, I have been having some trouble with ChartWrapper and a custom data source url. I poked around on this list and elsewhere and didn't see anything that quite matched my experience so I am hoping someone could offer me some pointers. I have used the gviz_api.py python module
http://code.google.com/apis/chart/interactive/docs/dev/gviz_api_lib.html to create a JSON response: google.visualization.Query.setResponse({'version':'0.6', 'reqId':'0', 'status':'OK', 'table': {cols: [{id:'latency',label:'latency',type:'string'}, {id:'count',label:'count',type:'number'}],rows:[{c:[{v:'-inf'},{v: 385.0}]},{c:[{v:'15.0'},{v:2319258.0}]},{c:[{v:'25.0'},{v:4781117.0}]}, {c:[{v:'35.0'},{v:223345.0}]},{c:[{v:'45.0'},{v:135157.0}]},{c: [{v:'55.0'},{v:108485.0}]},{c:[{v:'65.0'},{v:118934.0}]},{c: [{v:'75.0'},{v:85136.0}]},{c:[{v:'85.0'},{v:19281.0}]},{c:[{v:'95.0'}, {v:17479.0}]},{c:[{v:'105.0'},{v:10407.0}]},{c:[{v:'115.0'},{v: 16392.0}]},{c:[{v:'125.0'},{v:11487.0}]},{c:[{v:'135.0'},{v:13664.0}]}, {c:[{v:'145.0'},{v:575.0}]},{c:[{v:'155.0'},{v:0.0}]},{c:[{v:'165.0'}, {v:0.0}]},{c:[{v:'175.0'},{v:0.0}]},{c:[{v:'185.0'},{v:0.0}]},{c: [{v:'195.0'},{v:0.0}]},{c:[{v:'inf'},{v:0.0}]}]}}); and I have saved this to a file on my web server named latency.txt. I am having difficulty interacting with this as a data source url. I observe the following behavior. 1) If I include a single ChartWrapper that sets the dataSourceUrl to 'latency.txt' it mostly works. The chart is displayed. It does *not* refresh and it sometimes does not even reload properly when the entire page is reloaded. 2) If I try to make two ChartWrappers from the same source (or any similar source on my web sever) then only one is displayed. 3) If I have a single chart and try to use the Chart Editor then one of two things happens a) If I have the page load by first bringing up the chart editor it works, but any attempt to draw the chart on the page after clicking 'ok' fails. b) If I have the page load by first drawing the chart then the chart is drawn, but if I click on a button to open a chart editor the chart editor displays but then just spins as if it cannot access the chart data. My main question is, should this work at all (providing a static JSON response in a file on the server)? If so, what could be going wrong? I have tried this on both firefox and chrome. I have pasted my html below for example 3b). Any suggestions would be highly appreciated. best wishes <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http:// www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <meta http-equiv="PRAGMA" content="NO-CACHE"> <title> gstlal viz </title> <script type="text/javascript" src="http://www.google.com/ jsapi"></script> <script type="text/javascript" src='https://www.google.com/ jsapi?autoload={"modules":[{"name":"visualization","version":"1"}]}'></ script> <script type="text/javascript">google.load('visualization', '1.0', {packages: ['charteditor']});</script> <script type="text/javascript"> var wrapper = new google.visualization.ChartWrapper({ 'chartType':'LineChart' }); var chartEditor = new google.visualization.ChartEditor(); google.visualization.events.addListener(chartEditor, 'ok', update_chart); function draw() { wrapper.setDataSourceUrl('latency.txt'); wrapper.draw(document.getElementById('vis_div')); } function update_chart() { wrapper = chartEditor.getChartWrapper(); draw(); } function loadEditor() { chartEditor.openDialog(wrapper, {}); } google.setOnLoadCallback(draw); </script> </head> <body face="Arial"> <table border="10" cellpadding="1"> <tr><td><div id="vis_div" style="height: 250px; width: 400px;"></div></td><tr> <tr><td onClick="loadEditor()"><i>This is a table caption</i></td></tr> </table> </body> </html> -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
