The "->" button at the top right gives access to another
toolbar.
The "
Ratio
" option displays a table summarizing the ra-
tios between SP and AP on all the curves. The percent-
age ratio is obtained with the following formula:
𝑅𝑎𝑡𝑖𝑜 𝑆𝑝/𝐴𝑝 =
𝑆𝑃 − 𝑍𝑒𝑟𝑜
𝐴𝑃 − 𝑍𝑒𝑟𝑜
A click on one of the lines of this table enables to con-
sult the curve individually.
This gives a more detailed curve, for instance, to place
the markers more accurately.
Click on return to come back to the multi-curve win-
dow.
