Custom Chart Data Lables Moving Incorrectly

[abupu]

Hey All,

I'm just stuck on a problem.

I have a line chart with units on the y axis and months on the x axis. On the x axis is currently 12 months, Jan 2012 to Dec 2012.

Above each point on the line drawn i've added custom labels with custom text to give a bit more detail about that particular point.

The problem i'm having is I need to updated this chart monthly with a new month being added and the first month in the chart removed. For example, the line chart is Jan 2012 to Dec 2012 in the next month it should be Feb 2012 to Jan 2013 and so on.

Is there a way to make this change but still keep the custom data labels matched up in the exact same corresponding points / months?

I've tried adding a month in the data table and then extending the chart data selection area and that works perfectly. But, when go to delete the first month which needs to be removed, all the chart labels shift forward for some reason making them incorrectly line up.

Thanks in advance!

Hi Abupu,

You can use the offset function combined with a Count of the column to create your entire chart dynamically.

Using the count function you can find the last row of entered data for each part of your graph, then using the offset function you can look up from that last point to find the previous 12 entries. This way you can chart only the last year.

Here is an example:

Good luck!
