Agreed. upstairs. The proportion of stocks with small fluctuations is set to be large, and the displayed curve is almost a straight line without fluctuations. On the other hand, if the time-sharing jumps up and down badly and the icon ratio is too small, there will be a big picture that can't be seen by beheading.

Therefore, considering the above situation, when the stock price suddenly fluctuates greatly, the software designer will automatically change the vertical coordinate ratio to display the image optimally.
