I found ChipChop's chart function a little difficult to use, so I'd like to make a suggestion.
When the screen is reduced, the scroll bar can be moved easily,
but when you try to move the scroll bar when the screen is enlarged, the screen moves along with it, which is inconvenient.
For example, what if we placed right and left buttons next to the plus and minus buttons, so that pressing the right button would move the scroll bar to the right, and pressing the left button would move the scroll bar to the left? I know you're busy, but I would appreciate it if you could consider this.
