AChartEngine透明背景 [英] AChartEngine transparent background

问题描述

我有一个问题。我正在与AChartEngine一个图，我想有全图的背景是透明的：

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：

But it isn't working properly:

正如你所看到的，有一个黑盒子后面出现的x标签。我究竟做错了什么？

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

在前进，
谢谢 yellos

Thanks in advance,

推荐答案

尝试setMarginsColor（Color.argb（0×00，0×01，0×01，0×01））;它看起来像有设置颜色为黑色，当一个bug透明

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