I get this when viewing nodes:

"warning: Division by zero in /home/vughosting/public_html/drupal6-cluster1/public/sites/rickvug.com/modules/chart/chart.module on line 399."

Note sure yet if this happens 100% of the time or any other factors contribute to the issue. Going to say that this is critical.

I believe this is due to chart API module assuming the max value is ALWAYS over 0, which it isn't

-> #594202: Division by zero error

I could easily be wrong though

Rick, do you have any way I can reliably reproduce this bug?

for me it happens when the bounce rate for a certain page is 0% ... I think

same issue here, in conjunction with chart API, if no Values in charts

Im also getting this error, and can confirm it seems to be connected to the bounce rate being zero

To reproduce go to reports/google_analytics_reports.module and temporarily change:

    $chart_bounce_rate[] = number_format($row['bounces'] / $row['uniquePageviews'] * 100, 2);

to 

    $chart_bounce_rate[] = number_format(0 / $row['uniquePageviews'] * 100, 2);
      /* simulate bounce rate of zero */

Then view a chart of the bounce rate.

I applied #594202: Division by zero error as suggested by seutje in comment number 4, above; and that works.

In my opinion this is a chart problem but I'll let the maintainer confirm that. Thanks,

Albert.

The best direction is to get these patches applied to chart module: http://drupal.org/node/594202

However, I added a little tweak to help avoid this for the time being. I'd like to move away from this solution in the future but it should work for now: http://drupalcode.org/project/google_analytics_api.git/commitdiff/fbe4acc
