Hello,

create a second data series for the 45 degree line, for example

X Y

0 0

1 1

Add this series to your scatter plot, then send it to the secondary axis and set the min to 0 and max to 1 on both the secondary X and the secondary Y axis. Format with line and no data markers.

"send it to the secondary axis" How do I do this?

I took a look at the link at is says In A1: =ROW()

In B1: =ROW()

copy A1 and B1 down, let's say 20 rows.

Select A1:B20, Insert>Graph and choose a line graph

This is not helpful. When I click on A1 and enter =ROW() and then I try to go to B1 it stays in A1 and turns into =ROW()+B1. If my data is in column C & D. How would I do this? It also says choose a line graph, but I need a scatter plot not a line graph. I just need a line within the scatter plot.

Hello,

>> "send it to the secondary axis" How do I do this?

I take it that adding the new series to the chart is not the problem? After doing that, select the newly added series, then open the Format dialog, e.g by right-clicking and selecting "Format Series".

In Excel 2003 the command is on the Axis tab. Select the Secondary Axis radio button.

In newer versions, it is on the Series Options tab.

With the new series on the secondary axis, format the secondary Y axis scale to be minimum 0 and maximum 1. Then you need to switch on the secondary X axis temporarily, to be able to format it:

XL 2003 and earlier: Chart > Chart Options > Axes tab > tick the Secondary > Value (X) axis box

XL 2007 and later: Chart Tools > Layout > Axes button > Secondary Horizontal axis > Show default axis.

Since the commands are so different in various Excel versions, it is always good to know what version of Excel you're working with.

Excel for Mac 2008 version 12.2.7 (100910)

I have attached my excel file with the data. I am can you should me what needs to be done? I am unclear on exactly how to spread the 0 & 1 data points in the column to create the line. Also, I do not want my domain & range to necessarily be one.

Hello,

I have no clue what you mean with "domain & range".

See attached for your updated chart. I applied exactly the steps I described above. Excel 2008 for Mac is similar to Excel 2007.

I left the secondary axes visible, but you probably want to hide them. Click each of the secondary axes, then open the formatting dialog and set

Major tick mark type = none

Minor tick mark type = none

Axis labels = none

Ok. The domain and range is the minimum to maximum values of X & Y. The line looks good but how would I get rid the the vertical & horizontal secondary axis text boxes? on the top and right of the chart graph?

When I try to delete the secondary horizontal & vertical value axis the line moves. IT is possible to remove this without moving the line? Otherwise the numbers will be confusing.
