Hi,
I would like to know how or is it possible to add an average curve to the 3d trajectory graph. Let's say we have three-dimensional data (X,Y,Z) and my aim is to add a curve (in this case the curve will be a straight line actually) that is parallel to the given dimension e.g. Y representing an average value calculated on the values of Y through the whole data series.
values of Y: 12 10 10 14 14 12 10 16 14
and the average curve for those data will be constant and equal to 13.5
Add a new column to your worksheet, select the column, right-click the selection and choose Set Column Values. Enter this expression: mean(col(2)) and click OK, which puts the mean of your Y data in the new column (assuming column 2 is your Y). Now right-click on the layer1 icon in the upper left of your graph and choose Plot Setup. Uncheck the Y box next to column B. Check the Y box next to column D. Click Add. Click OK.
