MPAndroid图表饼图标签被切断

概述Hey Guys所以我一直试图弄清楚如何修改MP Android图表库中的饼图以不切断标签,我尝试用chart.setExtraOffsets()和chart.setPadding()修改视口.以及尝试使用视图端口处理程序来使此饼图适合视图. public void setupInventoryChart(PieChart chart) { chart.setUsePercentV hey Guys所以我一直试图弄清楚如何修改MP Android图表库中的饼图以不切断标签,我尝试用chart.setExtraOffsets()和chart.setpadding()修改视口.以及尝试使用视图端口处理程序来使此饼图适合视图.

public voID setupInventoryChart(PIEChart chart) {        chart.setUsePercentValues(false);        chart.setDescription("");        chart.setDragDecelerationFrictionCoef(0.95f);        mtf = Typeface.createFromAsset(getActivity().getAssets(),"OpenSans-Regular.ttf");        chart.setCenterTextTypeface(mtf);        chart.setDrawHoleEnabled(true);        //chart.setHolecolortransparent(false);        chart.settransparentCirclecolor(color.WHITE);//        chart.settransparentCircleAlpha(110);        chart.setHoleRadius(58f);        chart.settransparentCircleRadius(61f);        chart.setDrawCenterText(true);        chart.setRotationAngle(0);        chart.setRotationEnabled(true); // enable rotation of the chart by touch        // mChart.setUnit(" €");        // mChart.setDrawUnitsInChart(true);        // add a selection Listener        chart.setonChartValueSelectedListener(this);        chart.setExtraOffsets(0.5f,0.5f,0.8f);        //chart.animateY(1500,Easing.EasingOption.EaseInOutQuad);        // mChart.spin(2000,360);        Legend l = chart.getLegend();        l.setEnabled(false);       // l.setposition(Legend.Legendposition.RIGHT_OF_CHART);      //  l.setXEntrySpace(7f);      //  l.setYEntrySpace(5f);      //  l.setYOffset(0f);      //  l.setTextcolor(color.BLACK);        setInventoryData(chart);    }    private voID setInventoryData(PIEChart chart) {        //This defines the order of  how the data is shown.

解决方法 我面临同样的问题.我用下面的代码解决了这个问题.

pIEcPIEChart.setExtraBottomOffset(20f); pIEcPIEChart.setExtraleftOffset(20f); pIEcPIEChart.setExtraRightOffset(20f);

希望它会帮助某人.
