Hi Yuriy,
There is no function right now to set where the axis cross should be. Currently it is at 0 @ 0 and this cannot be changed.
However, you can modify the y function and use a label conversion as a trick.
Consider the script:
-=-=-=-=-=-=-=-=-=-=-=-=
b := RTGrapher new.
d := RTData new.
d points: (1 to: 3.14 * 2 by: 0.05).
d y: [ :x | x sin - 4 ].
b add: d.
b
-=-=-=-=-=-=-=-=-=-=-=-=
It is rendered as:
If you wish to have the X-axis at Y = -4, then you can do:
-=-=-=-=-=-=-=-=-=-=-=-=
b := RTGrapher new.
d := RTData new.
d points: (1 to: 3.14 * 2 by: 0.05).
d y: [ :x | x sin - 4 + 4].
b add: d.
b axisY
labelConversion: [ :y | y + 4 ].
b
-=-=-=-=-=-=-=-=-=-=-=-=
You can set the X-Axis at Y = y by adding y in the function provided to y: and in the label conversion.
I have written something on
Cheers,
Alexandre

Hi,
is it possible to use grapher and not have a 0@0 point in the view? I cannot find this in code nor in examples.
Cheers.
