User error bars in such **3D graphs as** XYZ 3D scatter, matrix 3D scatter, 3D color fill surface, and 3D color map surface. Your graph should now look like this: The error bars shown in the line graph above represent a description of how confident you are that the mean represents the true impact Besides, confidence interval is a product of standard error* T-student from the table with defined DF and alpha level. First click the line in the graph so it is highlighted. my review here

A positive number denotes an increase; a negative number denotes a decrease. Percentage – Specify a percentage error range and Excel will calculate the error amount for each value.
