"Price/yield simulation" area in the Bond Calculator
In the "Price/yield simulation" area, you enter either the yield or the clean price in percent. If you added a bond to the widget (by dragging it from a different widget, for example), then the fields are already filled with the corresponding (snapshot) yield and price value.
Start the analysis using the corresponding "Calculate" button. In the "Results" area below, you see the result of the calculation.
