Hello! My problem was that I placed all the build data in the `build` directory. A few days later the administration fixed it. I do not know what exactly your problem is, but try to contact @dmcatelegram. Thx for reporting, hope you will resolve you problem too!
The view button is displayed for single column chart.

The text in the switched off buttons is not centered.

Not a bad work in general. Doesn't deserve so many dislikes. No dislike from me for sure.

Thx for reporting. I think these dislikes is revenge for my spam about problem with deploying my app. But it has worked!
