Excluding Some Data from a Chart

Pam keeps a month's worth of data in a table and created a chart based on that data. The data was collected from information generated on her company's shop floor. The data includes weekends, but Pam doesn't want the weekend data included in the chart. She knows that she could hide the rows and they would be excluded from the chart, but she still needs the hidden rows to be displayed in the table. In other words, she wants them displayed in the data table, but not in the chart.

There are a couple of ways you could approach this problem. One is to simply make a copy of your data (maybe copy the whole worksheet) and then delete the rows that contain weekend data. You would still have your master data for whatever purposes you need, but you could base your chart on the modified copy of that data.

The drawback to this, of course, is that it creates two sets of data that may need to be updated or kept in sync in some way. It may be better to base your chart on a non-contiguous data range. Assume, for a moment, that your data was in A1:B15, and that there were weekends in rows 7, 8, 14, and 15. You could, within the chart, set the data range for the source data to this:

=Sheet1!$A$1:$B$6,Sheet1!$A$9:$B$13

You could also create a named range that refers to the non-contiguous ranges you want included in the chart. You could then use the named range in your chart, as a reference to the source data.

Finally, if you don't mind adding another column to your data, you could use the new column for your chart source. Assume, for a moment, that your readings are in column A and the dates of those readings are in column B. In each cell of column C you could place the following formula:

=IF(WEEKDAY(B1,2)>5,NA(),A1)

You then end up with a series of readings for all weekdays; the weekends show #N/A for the reading. You can base your chart on this data and Excel will ignore the #N/A values. You can even hide column C so it does not distract from your source data.
