Beautify Log/Log list plots with bad X scale

[axkr]

Please beautify Log/Log list plots with bad X scale.

Also the origin of the plot is set in point (1,1) but should be set in (0,0).

This problem still exists:

Also the origin of the plot is set in point (1,1) but should be set in (0,0).

Any suggestions how to tackle this? Do we need to provide more information in the data to make this easier for jsxgraph?

Please apologize my ignorance. My understanding is that $(1,1)$ = $(e^0, e^0)$ and therefore the point $(1,1)$ is at the x-/y-intercept of a log / log scale axis.

Please apologize my ignorance. My understanding is that ...

yes I think I've used a wrong example.

I created this new jsFiddle:

• https://jsfiddle.net/axelclk/8mvz61h0/2/ with the x/y values calculated with the ln function.

For the x/y scales I think I need a possibility to calculate the x/y "inverse" scales with the exp function.

"axes": {
    "hasaxes": [true, true],
    "scaling": ["exp", "exp"]
  },

Is there a general way to define a "mapping function" for the scales, which can be calculated by jsxgraph? For example defining formulas for x and y like "scaling": ["exp(x)", "y^10"] or something similar ?
