When trying to use TSeriesBandTool, we noted that the colour of the band was incorrect compared with previous versions of TeeChart. We traced this to the TTeeCanvas.AssignBrush overloads, which swap BackColor and Color. These overloaded functions are used in many places, some correctly, some incorrectly; it's quite inconsistent.

Procedure TTeeCanvas.AssignBrush(ABrush:TChartBrush);
begin
AssignBrush(ABrush,ABrush.BackColor,ABrush.Color);
end;

Procedure TTeeCanvas.AssignBrush(ABrush:TChartBrush; ABackColor:TColor);
begin
AssignBrush(ABrush,ABackColor,ABrush.Color);
end;

(snip)

// deprecated, please use AssignBrush
Procedure TTeeCanvas.AssignBrushColor(ABrush:TChartBrush; AColor,ABackColor:TColor); // deprecated;
begin
AssignBrush(ABrush,AColor,ABackColor);
end;

Procedure TTeeCanvas.AssignBrush(ABrush:TChartBrush; AColor,ABackColor:TColor);

The following units use AssignBrush in various ways. There seems to be a real lack of consistency among them. It's not clear to me when the intent is to use BackColor and when the intent is to use Color, in many circumstances, but you'll be clearer on that. A brief review of them yielded:

Hi,

Thank you very much for reporting it and the time spent with the list. I've added it to the wish list to be revised asap (TV52016035).
