Loading CSV Data Into Line Chart

[AllThumbsGeekMember]

All,

My demo of this to myself is/was the Custom Line Styles demo and I have wasted the whole day trying to get it to work for me. Could some one tell me where I am going wrong? The page creates the directory for the results and successfully writes the comma delimited file there, so it being there is NOT the problem. I hope I am using the code tags correctly…

Thanks,

ATG


// New chart data source setup
var chartsource =
{
datatype: "csv",
datafields: [
{ name: 'Hop' },
{ name: 'Time' }
],
url: 'results/google.com.txt'
};
var chartAdapter = new $.jqx.dataAdaptor(source, {async: false, autoBind: true, loadError: function (xhr, status, error) { alert('Error loading "' + chartsource.url + '" : ' + error); } });
var hops = ['Hop 1', 'Hop 2', 'Hop 3', 'Hop 4', 'Hop 5', 'Hop 6', 'Hop 7', 'Hop 8', 'Hop 9', 'Hop 10', 'Hop 11', 'Hop 12'];

// prepare jqxChart settings

All,

Since there has not been any response to my post I thought I would update my own progress.

After several hours more comparing line from example to line from code I changed 2 things, but remain unconvinced either should be necessary. First change was I copied the dataAdapter code from the demo and pasted it underneath my dataAdapter code so I could line things up. The difference was a space in the dataAdapter line after { and before the word async from demo to my code. In anguished desperation despite the trivial possibility of it making a difference, I added the space. Second was that I changed the entire web root file system on my Fedora laptop using chmod -R 0777 from /var/www/html. After losing a full day this works on my laptop. I note that the downloaded archive demos do not require more than chmod 0755 to run just fine…

Unless anyone has any words of wisdom I am moving on to importing yet another multidimensional array into a grid control.
