Smart Zoom:
------------

You can focus on a smaller area of your curves by using the pinch gesture on your trackpad or by using the mouse-wheel while pressing the command key. As you change of the x-range the y-range will be optimized.

Depending on the position of the mouse pointer, the pinch gesture keeps certain range parameter constant. For example, if you pinch below the main x-axis, the y-axis will not change. With a two-finger swipe you can move the x- and y-range.


New in Formula:
----------------

Since version 4.2, formulas can calculate x- and y-values in parallel. The following formula creates a circle when you press "show".

w:=2*pi*i/(targetLength-1);
x:=r*cos(w);
r*sin(w)

The compare operators <= and >= are availible in formulas. The functions odd(), isnan(), randomgauss(), hypot(), and trapezoid() are now availible in formulas.

trapezoid(x, x0, a, width, ramp [, period]) is a rectagular function if ramp=0. If ramp>0 there is ramp-up and ramp-down part of length ramp*width each. If the parameter period if supplied, the profile will repeat.

hypot(a,b,...) is square-root of a^2+b^2+...
