What's wrong with BarWidth?

[ren37]

Hello

ChartControl.BarWidth is less than actual bar width on chart.
This code results picture below.

            private void CalcBounds()
            {
                int w = indicator.ChartControl.BarWidth + 4;
                int x = indicator.ChartControl.GetXByBarIdx(indicator.BarsArray[0],Trade.StartBarIdx) - w / 2;
                ...

           public void Draw(Graphics graphics, Rectangle drawRect, Font fontVolText, Brush brushVolText, StringFormat sfVolText)
            {
                CalcBounds();

                if (drawRect.IntersectsWith(bounds))
                {
                    graphics.FillRectangle(brush, bounds);
                    graphics.DrawString(Trade.Volume.ToString(), fontVolText, brushVolText, bounds, sfVolText);
                }
            }

Hello ren37,

The bar width is the width from the center of the bar.

Does (ChartControl.BarWidth * 2) provide you with the correct value?

Yes, thank you.
