Here U can see version, which is "optimized for mobile devices" more than the previous one. Obviously, the big "pads" are more comfortable than the little checkboxes...
But there is a heardache about the selector (5 various charts). Like a checkboxe a selector is not very finger-oriented component of HTML. Moreover, during the previous stage of the context there was a practice, that all 5 charts should be visible simultaneously. I don't know, is it a demand or not, but before a day I realized, that to get rid from the selector I should rebuild all my project profoundly. I could not do it. I have a idea to use frames (every page has an argument, which means position of our selector). There is an example. Maybe, it is a proper way to get free from selector? In any case I don't throw the selector away and I made it bigger by css.There will be a next phase (I will add zoom)
