Scaling and alignment issues in the plot of calc_CentralDose()

[DirkMittelstrass]

There are two issues with the plot returned by calc_CentralDose()

1. For small plot sizes, the text is not aligned well
2. Depending on the data, the y-axis does not scale well. In the example screenshot a "log likelihood" of -1500 mathematically not reasonable and the starting part of the graph does not contain useful information. Even exp(-100) = 3.720076e-44. A more reasonable scaling would be for example 1 to 100 with the axis label "likelihood [%]". Or the scaling depends on the likelihood limits.

By the way: It might be more reasonable to return a radial plot (plot_RadialPlot()) as this is the type of plot which was also used in the original publication for the CAM method Galbraith et al. (1999).
