    One rogue data point in new 2 axis line chart

    Hi All,

    I'm still using Excel 2002, so try not to laugh. I have a table that's 7 x 26500 for logging my blood pressure and weight. Just added the weight column about 300 cells ago. At that time, I graphed my weight in a simple 1-axis chart, which works as expected. Now I've decided to make a new 2-axis chart with X = date and Y = weight. It all came out the same with one exception. There is a "stuck" data point on this new chart that's there (but wrong!) and cannot be cleared. From the table, it's row #1384 which has my weight at 223.6 while the chart value shows 216.8. I can (temporarily) delete this row and multiple rows above and below it, yet the chart value persists. I will attach a screen shot as the actual worksheet has too much personal data to scrub. FYI, the longer dip was when the wife was hospitalized for a week...

    The weight range is identical on both 1x and 2x charts, the 2x has a date range equal to the weight range with "A" column subbed for "G" column. Hope this enough info.

    TIA!

    Russ

    Re: One rogue data point in new 2 axis line chart

    I cannot say that I have ever seen this before in any version of Excel. I don't think there is much we can do on this side of the internet to debug with only pictures to work with.

    Debugging steps I would try:

    1) Check that calculation is set to automatic. Maybe force a full recalc (ctrl-shift-F9??). Maybe even save-close-reopen.
    2) Check the series definition (source data dialog) and make certain it is correct.
    3) Make other changes to the chart's source data and see if those changes get correctly reflected in the chart.
    4) Search for any instance of 216.8 elsewhere in the data or 11/2/21 or other typographical error in the source data.

    I don't think we can debug this for you from this side of the internet without a sample file, and, the process of creating a scrubbed file may scrub whatever is causing the error. If you can describe in detail your debugging steps, we may see something that we cannot see now. We'll help as best we can, but this may be difficult.

    Searching "216.8" did it, thanks! I found that I'd dropped a zero from what was supposed to be 11/20/21 so it ended up as 11/2/21. Since my table is unordered, the row with the rogue cell was in an unexpected place, searching found it, and correcting it put the point in the correct location on the chart.

    Glad that found the problem.
