Chart refreshInterval

[ksraj]

Hey Guys,

I currently have this code to draw my chart:

    google.setOnLoadCallback(drawPie);
      
    function drawPie(){
      google.visualization.drawChart({
        chartType : 'PieChart',
        dataSourceUrl: 'http://localhost:8080/pietime/',
        refreshInterval: 5,
        containerId: 'chart_div'
      });
    }

For some reason though, the chart never updates. I set the refreshInterval so I assumed that would work for now?

Does it draw the first time?  If it does, is your data actually being updated or is it pulling the same data over and over again?

Hi,

I had same problem. Example on google page works
https://developers.google.com/chart/interactive/docs/fusiontables?hl=pl
so why our tries didn't work.

Now i know... For me was global visibility of my data source url.
Don't know why, maybe for google api (sounds dengerous).

Be sure that your url is not local and is visible for the Internet!

good luck and regards

What I noticed is that chart (I tried only barchart) autorefresh (through refreshinterval setting) works in development mode (through eclipse) but does not work in deployment mode (through GWT copiled project). From the server log, even the queries are not sent to the data source. Am I missing something here?
Any help on this is appreciated.
