Do you mean the lack of rest of charts?
Other charts are to be choosed by select. In my manual (there is a comprehensive manual beside the application) at page "/finger/Contest.html" I wrote my sorry about such a design. I used select because I preffered to concentrate on details. On other hand, I was not sure, a select is forbidden or not. But there I have also proposed a realization of the second design (making all the charts to be showed simultaneously) by help of tag "iframe" (/finger/Frames.html - I tested such a modification on my smartphone once, and it worked without any problems)

Do U mean the "select-oriented" design, like the previous previewer (Quiet Panda)?

I am aware of it, sir, and sorry. Due to design - I am a full looser, maybe :-)
In my work the switcher night/day, for example, is not realised at all :-)
I was running of time, and I decided to concentrate on the "back end" without looking back on the "front-end" design affairs

On other hand, the mechanic of the zoom is fully altered by me (I hope, my alteration will be approved)

Badly, despite of my concentration, I didn't realized a comparison with the same chart (a day ago and a week ago), which was demanded at zooming of the fourth chart (lack of time)

Thanks, Yuriy! Is it your genuine second name? Or your parents gave U the first name in honor of the pioneer of the manned space missions?
