AChartEngine 透明背景 [英] AChartEngine transparent background

问题描述

我有问题.我正在用 AChartEngine 制作一个图表，我想让整个图表的背景透明:

I have a problem. I'm making a graph with AChartEngine and I would like to have the background of the whole graph to be transparent:

XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();
(...)
renderer.setMargins(new int[]{0,0,0,0});
renderer.setApplyBackgroundColor(true);
renderer.setMarginsColor(Color.TRANSPARENT);
renderer.setBackgroundColor(Color.TRANSPARENT);
(...)
GraphicalView g = ChartFactory.getTimeChartView(this, dataset, renderer, "dd/MM");

但它不能正常工作:

如您所见，x 标签后面出现了一个黑框.我做错了什么?

As you can see, there is a black box appearing behind the x-labels. What am I doing wrong?

提前致谢，

Thanks in advance,

推荐答案

试试 setMarginsColor(Color.argb(0x00, 0x01, 0x01, 0x01));将颜色设置为黑色透明时似乎有错误

Try setMarginsColor(Color.argb(0x00, 0x01, 0x01, 0x01)); It looks like there's a bug when setting the color as black transparent
