问题描述

我已附上使用情况图表的屏幕截图.在红色框中显示传奇人物，他们正在削减饼形图. 下面是我的代码:

I have attached the screenshot of my usage chart. In red box display the legends and they are cutting in pie chart. Below is my code:

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);

有人知道答案吗?请帮助我解决此问题.谢谢.

更新:

下面是我要显示图表的xml文件.

Below is my xml file to dispaly chart.

</RelativeLayout>

问题 -每当我填充图形时，图形图例都会自动从底部裁剪.如果我将相同的图例放在中间，则工作正常，但问题仅在底部发生.

Issue - Whenever I populate the graph, the graph legends is automatically cropped from bottom. If i put the same legends in center then it is working fine but issue occurs in bottom only.

推荐答案

您是否尝试过使用xml属性android:translationY="-10dp"进行自定义?

have you tried customizing with xml attribute android:translationY="-10dp" ?

或view.setExtraOffsets(...);

您可以相应地管理dp.

更新

l.setYOffset(10f);
