What is the bitmap of a stock?

Dot chart is a chart that uses squares to record, analyze and predict the changing trend of market transaction prices. To make a map, we must first choose a drawing paper with a suitable proportion, with the vertical axis representing the price and each square representing a price level; The horizontal axis represents the price change, but note that this does not represent time, but represents the price change and change speed in the opposite direction column by column, and then "×" and "○" represent the price rotation or trend.

If it is hand-painted, it is still too much trouble. So many stocks, so many varieties, all hand-painted work is too much! We should not only ensure the validity of the point map, but also be able to predict the practicability of the target bit. You can use this tool to automatically generate a point chart, and you don't need to manually animate the chart, and you don't need to calculate the grid value yourself, and you can generate it with one click.
