Hi ,

I'm running from the IBM ZOS Unix system server and can issue the sample linechart successfully if I hard code values as see below. If I add a REXX do loop to the data and build the addrows, My source returns a chart without data. If I HARD code the say statements, it works and I can see it in the browser. I'm reading in a file via readfile and parsing the values via rexx. Any ideas ? I

Thanks in advance !

Michael

Hi Michael,

The main problem is that your generated data is not correct, resulting in a syntax error that basically stops everything. Notice these lines:

dataTable.addRows([

// Instantiate and draw the chart.

var formatter = new google.visualization.DateFormat({pattern: 'yyyy/MM/dd'});

There is no rows of data following the addRows() call.

So adding the "Do" loop in your server-side code is not doing what you expected. You'll have to solve that before you can proceed with this approach.

Resolved. Unix file permission was not set. The older server ran as administrator and didn't care about permission bits.
