Manual Trend lines
Hi,
I've been trying to generate a graph of sales info and attach a trend line to it. Due to the style of graph that is required (a very complex stacked bar with) when I try to use the "Add Trend Line" the trend does not work. So what I want to do is manually calculate the values for each x value so that I can then plot these as a line on the graph. I can sort out the plotting of the values, but I have no idea how to calcluate the values. I've read numerous items on trends and as I'm not a stats person much of it doesn't make sense. The data I have is: Month1 5165 Month2 6332 Month3 3060 Month4 5862 Month5 5120 Month6 7518 Thanks Andrew |
Manual Trend lines
To generate the 'equation' you will need the x-values to be numeric
1,2,3.... Then look at SLOPE and INTERCEPT function in Help and at LINEST If you want to fit to a polynomial (power curve) look at http://people.stfx.ca/bliengme/ExcelTips/Polynomial.htm best wishes -- Bernard V Liengme www.stfx.ca/people/bliengme remove caps from email wrote in message ups.com...
