My Data Series contains blanks as the result of formula calculations. The
location and number of blanks can change with each recalculation as input criteria change. I can make my Chart ignore an "Empty" cell easy enough but my cells still contain the formula which created the blank ("") cell and therefore, not truely empty. I want to plot the series, about 7000 values, without the blanks showing up as zeros and ruining my trendline fit. Removing those rows is not an option as I have to retain the x-axis value as place holder on the chart. Thanks for your help; nothing is as simple as it seems when you start Dan |

That is certainly an improvement, thanks a lot.

It's something you will have to check on and decide for yourself. -- Regards, Tushar Mehta www.tushar-mehta.com Excel, PowerPoint, and VBA add-ins, tutorials Custom MS Office productivity solutions |

There are several thousand of them scattered about and they change with each
itereation so there would have to be an automatic way to do it. Thanks for the reply "Jon Quixley" wrote: Have you tried hiding the offending rows ?

Removing those rows is not an option as I have to retain the x-axis
value as place holder on the chart. So you're making a line chart and not an XY chart? This may play havoc with your trendline formula, since Excel calculates line chart categories as 1, 2, 3, etc. - Jon ------- Jon Peltier, Microsoft Excel MVP Peltier Technical Services Tutorials and Custom Solutions http://PeltierTech.com/ _______ XLADLK wrote: My Data Series contains blanks as the result of formula calculations.

Hmm, that may be why the trendline isn't fitting just real well but I don't
know of a better way. It's like plotting the number of people injured by tornados each month for the last 20 years and then running a trendline through only the Cat 5's. The next iteration might be only Cat 3 and above. A given month may or may not have a value depending on your criteria. See my problem? Suggestions are welcome.

I guess I'd try filtering the data, extracting the Category 5s to a new
sheet and analyzing that subset. Another option would be a pivot table, because you can sort the storms by cateogyr, and group the dates by month or year. I'd also put the data onto an XY chart. - Jon ------- Jon Peltier, Microsoft Excel MVP Peltier Technical Services Tutorials and Custom Solutions http://PeltierTech.com/ _______ XLADLK wrote: Hmm, that may be why the trendline isn't fitting just real well but I don't know of a better way.

Have you found the answer yet?
I am trying to plot a data series also through months. If the month is not here yet, the cell is calculated to be blank, but the chart is plotting it as zero. Is this similar to your situation? How did you fix it? Thanks "XLADLK" wrote: My Data Series contains blanks as the result of formula calculations.

Option 1: Replace the "" in your formula with NA().
Option 2: If you don't like the ugly #N/A or it messes up downstream calculations, use another column in which you have the NA() instead of the "". Plot this new column but use the original for other work. Option 3: Adapt the ideas behind Dynamic Charts http://www.tushar-mehta.com/excel/ne...rts/index.html If you use COUNT() instead of COUNTA(), the solution will include only those cells with numbers and exclude the ""s. -- Regards, Tushar Mehta www.tushar-mehta.com Excel, PowerPoint, and VBA add-ins, tutorials Custom MS Office productivity solutions In article , says...

Jon, I'm having the same types of trouble here, but I tried using an xy
chart... It won't let me because my data source is a pivot table. I don't have formula's with blanks or N/As but I am summarizing data that it linked to other sheets, and it reads that formula as a vaule... Is there anything else I can do to get it to ignore the zero in my chart? "Jon Peltier" wrote: I guess I'd try filtering the data, extracting the Category 5s to a new sheet and analyzing that subset.

Don't make a pivot chart, make a regular chart. Select a blank cell outside
the pivot table, start the chart wizard. In step 2, go to the Series tab, and one-by-one add and populate the series you want. - Jon ------- Jon Peltier, Microsoft Excel MVP Tutorials and Custom Solutions Peltier Technical Services, Inc. - http://PeltierTech.com _______ "psipg" wrote in message ...
