我已经附上了我的使用情况图表的截图。红色框中显示了图例,它们切割在饼图中。以下是我的代码:
pieChart.setUsePercentValues(false);
pieChart.getDescription().setEnabled(false);
pieChart.setDragDecelerationFrictionCoef(0.95f);
pieChart.setDrawHoleEnabled(true);
pieChart.setHoleColor(Color.WHITE);
pieChart.setTransparentCircleColor(Color.WHITE);
pieChart.setTransparentCircleAlpha(110);
pieChart.setHoleRadius(55f);
pieChart.setTransparentCircleRadius(57f);
pieChart.setDrawCenterText(true);
pieChart.setRotationAngle(0);
// enable rotation of the chart by touch
pieChart.setRotationEnabled(true);
pieChart.setHighlightPerTapEnabled(true);
// add a selection listener
pieChart.setOnChartValueSelectedListener(this);
pieChart.animateY(1400, Easing.EasingOption.EaseInOutQuad);
Legend l = pieChart.getLegend();
l.setVerticalAlignment(Legend.LegendVerticalAlignment.BOTTOM);
l.setHorizontalAlignment(Legend.LegendHorizontalAlignment.CENTER);
l.setOrientation(Legend.LegendOrientation.VERTICAL);
l.setDrawInside(false);
l.setForm(Legend.LegendForm.CIRCLE);
l.setXEntrySpace(7f);
l.setYEntrySpace(0f);
l.setYOffset(0f);
l.setWordWrapEnabled(true);
l.setDrawInside(false);
l.getCalculatedLineSizes();
// entry label styling
pieChart.setEntryLabelColor(Color.WHITE);
pieChart.setEntryLabelTextSize(12f);
有没有人知道答案? 请帮我解决这个问题。提前致谢。

问题 - 每当我填充图形时,图例总是自动从底部裁剪。如果将相同的图例放在中心,则正常工作,但问题仅出现在底部。
