strengthFactor property
final
The factor that determines the strength / opacity of the dots along the axis direction.
The strength of a dot will be based on its position along the axis direction over the product of the total length of the axis direction and the given strength factor.
A factor of 1.0 means that the dots will fade from full strength at
one edge down to zero strength at the other edge. Meanwhile, a factor
of 0.5 means that the dots will fade to zero strength at half the
distance to the other edge.
