You mean to take yesterday's settlement price as the "central axis" of the "coordinates" in the time-sharing diagram interface, right (not the central line)? Is that so? If so, there is no software that can customize the coordinate axis. If you just want to observe the trend of the time-sharing chart and think that yesterday's closing price is the dividing point, then drawing a line is the simplest and most economical method. If so, explain what needs to be done to remedy the case. Wenhua's interface should be more user-friendly, but it only provides three ways to customize the coordinate range. You can say exactly what to do. Personally, I generally observe yesterday's main opening cost zone and the three lines of breakthrough and support (based on the real-time raw data algorithm of the exchange, not the general feeling or index definition), which will be more objective. I hope I can help you.
