S-curve Select the “Revenue” node by clicking on the icon to the left of the name. Click on the “S-curve” icon on the toolbar. A plot should appear on the screen. The Y-axis displays the variable´s cumulative probability of occurrence, while the X-axis displays the range of outcomes. The plot and the legend may e.g., indicate that the mean value is $5308.6, and that there is a 5% chance for the revenue to be less than $2614.32, a 50% chance that the revenue will be less than $4987.24, and a 95% chance that the revenue will be less than $9337.6. You may now use the results to decide whether to go ahead with the investment or not, and you may also produce other plots which further describe the results.
