Use cross-section values |
If the option has been selected, the mean value is calculated from both directions. If the option has not been selected, the values are determined separately for each direction. Note If an undirected value to be displayed is averaged, it is automatically divided by two, so that half of the undirected value counts as the upper limit for the scaling. If, for example, the scaling range is 1-1000 and the bar width is 10 mm, an undirected value of 2000 is displayed with a volume of 1000 on each side and a bar width of 10 mm. |
