are scatterplots possible?
I can't seem to get Excel to do what seems a very straightforward chart: a
scatterplot. I've got three continuous variables: A, B, C. Ideally, what I 'd like to do is to construct a plot with two of the variables on the X and Y axes and to encode the symbol based on the value of the third. Barring that, I'd just like to construct three separate scatterplots: Var A by Var B, Var A by Var C, Var B by Var C. Shouldn't this be reasonably simple to do in a program like Excel? Thanks in advance, David |

You can try a "manual" solution as found on = http://www.geocities.com/jonpeltier/...mMarkers.html= .. = I don't think this is what you want since the marker is not dependent on= a = variable. What you are *really* asking about is a three dimensional chart. Excel = is = fairly limited in that regard.

David -
First, you're aware that you can plot two variables in a scatter chart in Excel? In step 1 of the Chart Wizard, you select XY (Scatter), the fifth item in the left hand list, then one of the five options on the right. That's how you plot A vs B, etc. If you want your markers to be dependent on a third value, you can look at the conditional charting examples on my web page: http://www.geocities.com/jonpeltier/...ts/format.html You could, as Dave suggests, try a bubble chart, where the size of the marker scales with a third variable. Unfortunately Excel has very limited 3D charting capabilities, but Andy Pope has a way to simulate a 3D scatter chart on his web site. Look in the Charting section of http://andypope.info. - Jon ------- Jon Peltier, Microsoft Excel MVP http://www.geocities.com/jonpeltier/Excel/index.html _______ David Schwartz wrote: I can't seem to get Excel to do what seems a very straightforward chart: a scatterplot.
