log scale

[PerBorgvad]

Hello

I'm trying to display the net. force of two cylinders working against each other backed one accumulator each.

On the attachment, the blue plot shows the resulting force working towards the middel position.

The right y-axis, accumulator pressure,  is pr. yet scaled linear which is not correct.

The pressure is releated to volume (or stroke, x-axis) , as pr. p1*V^k = p2*V^k.

Practical k values in the range of 1.0 to 2.5

For the enclosed example :

I'd like to see the right y-axis min. value to 29.1 and the max value to 301.5 but the axis

scaled logarithmic with the base of 'k'

Anyone ?

Regards Per Borgvad

Can you not simply specify the graph to have a log scale for the axis in question? Its been a while since I've played around with logs to base k but IIRC its just a matter of applying the correct scaling to a generic log shaped function, which is what the CVI log graph gives you.
