A page you arrange yourself
The custom page starts empty. Add a widget and choose the data first: a force, a coefficient of the wing or of the airfoil, or a flow quantity such as the Reynolds number. Then choose what to show it against: the speed, the angle of attack or another quantity, which gives plots such as the drag polar.
A widget is a chart, a table or a single value. All of them follow the input data and the polar you loaded, and every chart has its own button that saves it as a PNG image exactly as it is shown.
Templates
A page holds up to ten widgets. Its layout can be saved as a template and loaded again later with other data; two templates can be kept.
Which values does a widget use?
The same ones as the other calculators: the air, the speed and the wing from the input data, and the coefficients of your polar at the chosen angle of attack, for the finite wing or for the airfoil section.
