Getting an Equation
Hey people. This may seem like a stupid question, but I have been told by my Uni lecturer that it can be done...but I have no idea how. Here's the thing: I have three points of data (-3.576, -4.200 and -6.908) at time (0,1,2) resectively. I kinda get how to plot them, but I want to get a line of best fit and then be able to get the equation for that line (eg. y=mx+b) He says you have to click on one f the points, but then I'm completely lost. Any help would really be appreciated!

First, your chart should be an XY scatter chart.
Select the series, right click and ADD TRENDLINE. Choose the regression type you want. Then Select the TREND LINE and double click. On the options tab, select DISPLAY EQUATION ON CHART and Display R-squared value on chart. "kahlua_bundy" wrote in message news:kahlua_bundy.1vhlub_1126933524.2661@excelforu m-nospam.com...

Making a line in a graph
Barb,
I am trying to graph my data using the regression feature. Can this be done? I've plotted my data using the chart wizard but I do not see an option that would allow Excel to graph the regression line through the points? paul "Barb Reinhardt" wrote: First, your chart should be an XY scatter chart.

Making a line in a graph
You don't want the "Regression" feature (which is in the Analysis Toolpak), you want
the "Trendline" feature (which is an in-built chart feature). Select the series, and on the Chart menu, choose Add Trendline, and follow the rest of Barbara's instructions. - Jon ------- Jon Peltier, Microsoft Excel MVP Peltier Technical Services Tutorials and Custom Solutions http://PeltierTech.com/ _______ sirsoto wrote: Barb, I am trying to graph my data using the regression feature.
