Bar chart: the highest form are incorrect on bars.

[4surix]

Explanation

In the bar chart, the upper part of the bars does not reflect the true value.
The solid parts (█) of the bars are mostly used, not ▄ and _.
This is due to incorrect writing of the conditions.

Regarding the condition where the value is equal.

The variables valeur_y and ligne_valeur_y are mostly decimal numbers. Sometimes these two variables are close, but not equal. Let's change the condition to take this into account.

Lines 244 to 249 in 57db5b8

	elif valeur_y == ligne_valeur_y:
	ligne += (
	CARAC_BARRE_H_EGA_COULEUR[index_baton] if couleur
	else
	CARAC_BARRE_H_EGA
	)

The part elif valeur_y == ligne_valeur_y: must be replaced with elif ligne_valeur_y - 1 < valeur_y < ligne_valeur_y + 1:.

Regarding the condition where the value is lower.

Here, the condition only applies if the bar in the diagram is lower than the first visible value on the y-axis. It must be valid for any size of bar.

Lines 251 to 257 in 57db5b8

	elif (min_valeur_y + palier >= ligne_valeur_y
	and valeur_y != min_valeur_y):
	ligne += (
	CARAC_BARRE_H_INF_COULEUR[index_baton] if couleur
	else
	CARAC_BARRE_H_INF
	)

The part elif (min_valeur_y + palier >= ligne_valeur_y must be replaced with elif (valeur_y < ligne_valeur_y.
