描述

Using combined chart view I'm trying to display semi transparent bar data with no spacing between the bars, but I'm getting some unexpected behaviour: setting the barWidth of the set to 1.005 gets me chart with bars that start with spacing between them, towards the middle gets perfect and towards the end bars start to overlap and which results of a solid color - a combination of the 2 semi transparent. gh5i4cp

Running the same code on smaller screens gets me spacing and on bigger screen - overlap.

研究方向
Investigate the bar width calculation in CombinedChartView. The issue suggests that setting barWidth to 1.005 causes inconsistent spacing on different screen sizes. Look for pixel scaling or rounding issues in the rendering code, possibly in BarChartRenderer or CombinedChartRenderer. Check comments and related issues for any known fixes or discussions about bar width and screen density.
