Group charts by week

[BugDebug]

I have a bar-chart that shows how many units were created by day. Days on the X axis and count on the Y axis.

I would like to have the same chart, but grouped by week, so I can see the total count by week, over time, so: Weeks on the X axis and count on the Y axis.

Any idea how I might achieve that? I have a timestamp field available, and I would rather not have the users input the week number in a separate field manually.

In the chart, records are not able to group by week. You can only group by Whole field, Hour, Weekday, Month, or Year.

The workaround is to use Combined Chart and Report DataPage instead of Charts DataPage: http://howto.caspio.com/datapages/creating-datapages/creating-a-combined-chart-and-report-datapage/combined-chart-and-report-example.html

Then you can add one calculated field in the results page to calculate the week. The Math function is :Datepart(week,[@field:date]). Go to Configure Chart Options, select this calculated field for X Axis.

Thanks a lot, again, you managed to solve the problem spot on. I now have it working.

Is there a way to get rid of the table below the chart, perhaps through some HTML code?

Have you tried to create a chart DataPage instead of combined report and chart?

[BugDebug]

Yes, and as far as I can tell, you can't create calculated fields in a chart only report.
