I have two groups of different types of mice called WT and KO. I've measured
the weight of twenty from each group. I want to make a chart with the X axis
being "WT" and "KO" and I want to have the Y-axis show all ten data points
for each group. How does one do this? I'm using Exel XP. Thanks.
 
Your question asks for 20 weights per group - for the sake of keeping things
short this example shows 5 weights per group. Set your data up in the
following manner with WP in cell A2, KO in cell A7, Mouse in cell B1, and
Weight in cell C1:

Mouse Weight
WP 1 2.1
2 3.4
3 1.6
4 1.3
5 4.8
KO 1 1.4
2 1.8
3 1.7
4 1.3
5 2.1

Select the range C1:C11. Go to the Standard Toolbar and click on the Chart
Wizard icon. In Step 1 of 4 of the Wizard, under the Standard Types tab
select the Line -> Line Markers Displayed at Each Value chart. Hit the Next
button until the chart appears on your worksheet.

Once the chart appears, click on it once and go to the Standard Toolbar.
Select Chart -> Source Data. Under the Series tab select the Category (X)
Axis Labels. Highlight the range A2:B11 and then hit the OK button. The
chart should now have two categories on the X axis - one for WT and one for
KO.

Double-click on the line series. In the Format Data Series dialog box, go
to the Patterns tab and select Line = None. At this point you can continue
to format the chart as you wish by adding data labels, etc. Data labels are
also accessed via the Format Data Series dialog box -> Data Labels tab.

You might also want to experiment with creating an XY Scatter chart with the
same data.
 
Thanks. That doesn't quite solve my problem. I'd like to present the data
where all the WT points are in a vertical formation and all the KO points are
in another vertical formation right next to it. That is, there will be only
two categories on the X-axis. Each category will have all ten data points
above it.
 
This is done by making a combination chart. Start with this data:

Dummy
WT 0
KO 0

Select this data and create a default column chart. You get WT and KO along the X
axis, and the columns don't appear because of the zero values.

Now put your data into this format, where 1=WT and 2=KO:

Group Weight
1 6.2
1 12.3
1 8.1
1 8.1
1 5.9
2 14.2
2 11.4
2 13.3
2 9.5
2 10.5

Select and copy this data, select the chart, and from the Edit menu, choose Paste
Special; choose the New Series option, with Categories in the First Column and
Series Names in the First Row. The chart now has some crazy columns, and the WT and
KO labels are far to the left. Let's fix that:

Select the new series of columns, and on the Chart menu, choose Chart Type and
select the XY Scatter type. Then on the Chart menu, choose Chart Options, click on
the Axes tab, and uncheck the Secondary X and Y Axis boxes.
