    I am creating frequency charts in excel, and I would like to be able to add a marker (maybe a vertical line) to indicate where the mean and the median are in the distribution. I dont want to have to do it manually, as the charts are changing often.

    Is there a way to automatically include a marker in a chart based on a data in a cell?

    Glad to see I'm not the only one in a difficult mood today.

    I'd like to see the answer as well because it's not something I've had to look for yet, but I may someday.

    (Just had a quick look and I'm sensing "Add Trendline" in the near future.)

    It would be nice if you could. But you dont have to.

    Okie, dokie...

    Suppose we have a range of values (named Sheet1!X) containing {2;3;3;3;1;1;2;1;3} which is summarized as {"Bin","Freq";1,3;2,2;3,4} (and whose columns are named Sheet1!Bin and Sheet1!Freq respectively). Before I start charting I'll create one more Defined Name, Sheet1!Mean, which refers to ={0,0}+AVERAGE(Sheet1!X).

    On to charting...

    1. Select an empty cell and choose the Insert | Chart... menu command to create a blank Column Chart.
    2. With the blank chart object selected type =SERIES(,Sheet1!Bin,Sheet1!Freq,1) into the formula bar.
    3. Once again with the chart object selected type =SERIES(,Sheet1!Mean,{0,5},2).
    4. Select the 2nd series, choose the Chart | Chart Type... menu command, and pick the XY (Scatter) Chart type and one of the sub-types on the 3rd row.
    5. With the chart object selected choose the Chart | Chart Options... menu command and uncheck the Secondary Axis for X and Y.

    Voila!! A histogram with a vertical line marking the Mean.
