Scatterpoot not using X values properly -- using relative ranking
I have created a scatterplot where the X value is to be one value (risk) and
the Y value is to be another (return). I've entered the X and Y value ranges properly and the y value is being plotted correctly, BUT the X value is not being plotted as the correct X value. Instead, the X value is being interpreted as the relative ranking in the list. In other words, # in list X value Y Value 1 12.2 13.7 2 10.7 11.3 etc. The graph is currently plotting the values as (1,13.7), then (2,11.3) and NOT with the correct X values as listed in the chart. I've checked the ranges and there's nothing indicating that the graph should look to the "relative position" for the x-axis value. What gives? thanks, Eric |

Scatterpoot not using X values properly -- using relative ranking
If you have 3 columns (i.e. the first column has 1,2,3), then Excel will
treat this as the x-values. To overcome this, select the x and y data before making the chart. If you have two columns, it sounds like you are making a Line chart because when Excel sees two ranges with numbers it uses both as data series and uses the ordinal values 1,2,3 ... for the category vales (x-values). This can be avoided by removing the title at the top of the x-values. Failing either of these, send me a sample file (get my email addy from my website) Tell me what version of Excel you are using best wishes -- Bernard Liengme Microsoft Excel MVP http://people.stfx.ca/bliengme "Eric_G" wrote in message ...

Scatterpoot not using X values properly -- using relative ranking
One possibility is that the X values are not numeric as Excel sees
them. In an empty cell in the first row with data enter =ISNUMBER({x}) where {x} is the cell containing the x value. Copy this down to cover all the rows with data. All the results should be TRUE. Another possibility is that you are using the Line Chart, which looks very much like a XY Scatter Chart but the x values are category values. If so, make sure you are really using a XY Scatter Chart.

Scatterpoot not using X values properly -- using relative ranking
Did you make a line chart? It will plot the data incorrectly.
Are the values in the X column really numeric, or are they text that looks numeric? It only takes one text value to mess it up, and Excel will convert the whole X range into 1, 2, 3, etc. - Jon ------- Jon Peltier Peltier Technical Services, Inc. 774-275-0064 http://peltiertech.com/ On 3/11/2010 12:45 PM, Eric_G wrote: I have created a scatterplot where the X value is to be one value (risk) and the Y value is to be another (return).
