The class Thermometer
implements a classical thermometer as
graphical Vole component. The final size of the thermometer depends on the
width-to-height ratio given by the constructor or the setBounds-method.
The thermometer is drawn that it completely fits into its bounding box.
A thermometer without any inscription has a width-to-height ratio of
2 to 7 plus text height. Any inscription will be drawn on the right side
of the fluid column, and with an inscription, the width-to-height ratio will change.
So, if the thermometer is too small or not visible at all, you should try to increase
the width first.
