Only the upper Canvas is working for some increasing functions!
(the lower Canvas is planned to be the same, to have a stator and a slider)

How to use:
1) Choose the function from the Upper Scale "increasing functions" menu. (This clears your previous session.)
2) Give the endpoints of the interval (use decimal point) or let the default.
NOTE: if the "=" (equality sign) appears before "xleft" then the left end of the interval can not be altered! The same if "=" is shown after the box of "xright".
3) Press DRAW1
4) Translations works by the buttons "<=" and "=>" (this will make the slide rule with two canvases to work in the future)
5) You can repeat 2)-4) above, but after 2) press DRAW1 again
6) choosing 1) clears all, so 2) and 3) are neccessary
7) the button "CLEAR" erases all 1)-4)
