Fixed bug: now building step does not depend on scale
The program allows draw functions graphs in specified area. The area is defined by the X min, X max, Y min, Y max values and division values for X and for Y. Functions are defined by the expression string and color. You should click on function string in the table to edit it. Only "x" symbol should be used as a varible. After area and functions data input click "Redraw" button to draw it. On phones graph is drawn on a full screen. Via the menu You can maximize graph on the full screen, get help about functions, about program, save the graph as a picture or sent e-mail with it (with help of mail client app,such as gmail). The advertisement will be shown after the 5 redraws, and may be closed via the menu (or shown). And please, sometimes click advertisement - it may help for developer))).
