I can't change the axis scale, using wheel or touchpad. When I move up or down, numbers on an axis grows. I can't "zoom out". Is the any other way to change the scale? Using keyboard for example

Use SHIFT+mouseWheel or CTRL+mouseWheel to change the scale of a single axis (x and y, respectively).

If you want a precise scaling, use a plugin (like X-Y Plot Region)

Or you have experienced a bug?
