Point-and-figure chart function issue

I used the point-and-figure chart function of mplfinance and have two issue. One is that the point-and-figure chart does not strictly follow the 1:1 ratio to draw each cell, that is, we can think of the canvas as a grid of countless 1:1 squares, and each X or O appears in the grid in order, no matter if it is enlarged or reduced our chart, this ratio is no change. The purpose of this is that the point-and-figure chart has an important technology called the “45-degree trend line”. We can use it to judge the later trend. If the point-and-figure chart is not drawn to scale, for example, there is a certain distance between the two columns, then the “45-degree trend line” loses its meaning.

The second issue is could the mplfinance can add a function, that is, the lines of every 5 rows and every 5 columns are thickened, just like the real graphics drawn on paper.

Thanks a lot for nice work of mplfinance.

Inizia individuando la funzione per i grafici Point-and-Figure di mplfinance e riproduci entrambi i comportamenti segnalati con un grafico di piccole dimensioni. Verifica come vengono calcolate le dimensioni delle celle e la spaziatura delle colonne, quindi definisci test per una griglia fissa 1:1 e per linee più spesse ogni cinque righe e colonne. Il lavoro è completato quando il grafico mantiene il rapporto della griglia a dimensioni diverse e visualizza le guide in stile carta richieste.
