Source Range
I have a sheet with four columns of data. The first column is date/time
information for the X-Axis. Every day, two new rows are added at the bottom. I have to manually change the source data range each time to include these newly added rows of data. Is there a way to specify that all rows containing data are to be included? I could specify, say, one-hundred additional rows but that would create a large empty area at the right side of the chart and unnecessarily compress the data to the left. Is there an alternate solution? Thanks in advance for any comments, /s/ Alan Auerbach |

Dear Jon,
Thank you so very much for the link that perfectly addresses my question. Jerry Latham referred me to you. He told me that if I post this question on the forum, I should cross my fingers that you see it! He was so right. You and he have been so very helpful and generous. I cannot thank you enough!

Dear Jon,
Perhaps I can add something to the discussion. I am certain this will be obvious to you, but it was not to me so it might help someone else who reads this thread. In my chart, not every cell contains data. Some values are updated once-a-day while others are updated twice-a-day and still others weekly. Since the date and time values are present in every row, they can be used to select the number of rows. In this case, I merely used that column (A, in my case) to derive the COUNTA value rather than a colum with data points. In this way, the graph included values in every row and can trend between values (or simply data-point) for those columns in which not all cells contain values. All that is necessary is to use the formula in the example you provided but maintain the COUNTA references the same for each data source, regardless of the column in which the data appears. I hope that this comment is of some value. :-) /s/ Alan Auerbach "Jon Peltier" wrote: Alan - Thanks for following up.

What I usually do is base all of my dynamic ranges on the X values or
categories, as you do with the dates. I define the X value range by explicitly counting values in the X value column. Then subsequent ranges (Y values) are simply based on an offset of this range: Given a properly defined range named Xvalues: Name: Yvalues1 Refers To: =OFFSET(Xvalues,0,1) Name: Yvalues2 Refers To: =OFFSET(Xvalues,0,2) etc. I initially did it this way to save typing, and only afterward realized that it made for more robust range definition. - Jon ------- Jon Peltier, Microsoft Excel MVP Tutorials and Custom Solutions Peltier Technical Services, Inc. - http://PeltierTech.com _______ "Alan Auerbach" wrote in message ...
