New article Developing custom indicators using CCanvas class has been published:
The article deals with developing custom graphical indicators using graphical primitives of the CCanvas class.
Unlike a simple arc indication, the sectional one looks as if it has
labels separating equal intervals. When creating a layout of the
indicator of this type, I have decided to make ten sections and add a
new element – the inner frame. The basic structure with the arc
sectional indication is presented in Fig. 5.
