Mapping of axes
This page shows some of the mappings of
axes.
Mapping linear
Please refer to the tutorial.
Logarithmic mappings: log10
, log2
, ln
If you want to visualize a function
f(x) in equal intervals
within a certain mapping, you can use the code shown below. Of course
you should replace Math.log10 and
Math.pow(10, ... ) with Math.log2 and
Math.pow(2, ...) or Math.log and
Math.exp(...) if you use the mappings
'log2' or 'ln', respectively.
Note that the following code draws a straight line (the red line in the figure below) on the graph, not a curve of y = x (the black curve).
Angle mappings degree
and radianAsDegree
The following two codes give graphically the same result. However, in one case the angle is internally computed in degree, while in the other case, radian are used as unit.
