Charts 如何在饼图中仅显示非零值？

我正在使用mpandroid图表显示我的数据。这里有5个xVAL（A，B，C，D，E）。每个xval都有一个yval（2.2,0.0,4.4,5.1,0.0,9.0）

我只想在饼图上显示非零的值。有没有办法做到这一点

所以我的数据最终是这样创建的：

PieData d = new PieData(xVals, ds1);

其中,， xVAL包含：

0 = "A"
1 = "B"
2 = "C"
3 = "D"
4 = "E"
5 = "entry0"
6 = "entry1"
7 = "entry2"
8 = "entry3"
9 = "entry4"

0 = {Entry@4129} "Entry, xIndex: 0 val (sum): 0.0"
1 = {Entry@4130} "Entry, xIndex: 1 val (sum): 7400.0"
2 = {Entry@4131} "Entry, xIndex: 2 val (sum): 20634.4"
3 = {Entry@4132} "Entry, xIndex: 3 val (sum): 0.0"
4 = {Entry@4133} "Entry, xIndex: 4 val (sum): 60203.52"

并且，ds1包含：

0 = "A"
1 = "B"
2 = "C"
3 = "D"
4 = "E"
5 = "entry0"
6 = "entry1"
7 = "entry2"
8 = "entry3"
9 = "entry4"

0 = {Entry@4129} "Entry, xIndex: 0 val (sum): 0.0"
1 = {Entry@4130} "Entry, xIndex: 1 val (sum): 7400.0"
2 = {Entry@4131} "Entry, xIndex: 2 val (sum): 20634.4"
3 = {Entry@4132} "Entry, xIndex: 3 val (sum): 0.0"
4 = {Entry@4133} "Entry, xIndex: 4 val (sum): 60203.52"

我建议您只编写自己的逻辑，将零值排除在数据集之外
