To draw the Error graph:
A B C 1 10 8.0988273 5 2 20 22.302867 8 3 30 32.619301 3 4 40 43.782683 2 5 50 46.560826 4
As with a line graph, the Error graph has a line connecting all the data points whose Y values are listed in column B. But similarly to the Hi Lo graph, the Error graph also contains a series of isolated vertical lines each of which is capped by a small horizontal tick. The horizontal ticks are placed equidistantly above and below the data points according to the values in column C of the spreadsheet. The horizontal location of each mark is set by the values in column A. You could also have created this Error graph by arranging the data into rows.
Just as with Hi Lo charts, Error graphs can show multiple sets of data.
