I am trying to scale the y-axis as follows:
0.1
0.4
0.8
1.6
3.2
6.4
12.8
25.6
51.2
102.4
204.8
406.9
819.2
I want the major units to double with each step up the y-axis, starting at 0.1 and terminating at 819.2.
The problem is, I have no idea how to achieve this! I tried using the logarithmic option in Excel, and also in OpenOffice Calc, but it was of little help and did not seem to allow me the flexibility I need.
The logarithmic option in Calc scaled the graph 0.1, 1, 10, 100, 1000. This does not provide enough resolution.
I was told Graphmatica ( http://www8.pair.com/ksoft/ ) will allow me to achieve my goal. But I have no idea how to use Graphmatica and there seem to be no tutorials for it anywhere? I do not even know where in Graphmatica i am supposed to enter the equations?
This is the formulae I would like to illustrate on a graph:
Tan(90-As)*1.205*pi*2
And also (on the same chart):
1.205/cos(90-As)*pi*2
Where:
As = Steering angle (0 to 90 degrees).
My intention is to illustrate the difference in turning circles between the rear wheel and the front wheel for a bicycle with a wheelbase of 1.205 meters.
Any help appreciated.
