使用mpandroidchart的饼图对齐问题

例如,您可以实现如下目标:

这是密码。当覆盖 piechart时,应该使用此代码。如果您没有覆盖它,您应该调整此代码以使用您的 piechart directly,例如 mchart.setdata(); instead of setdata();

PieDataSet dataSet = new PieDataSet(entries, null);
dataSet.setSliceSpace(3f);
dataSet.setIconsOffset(new MPPointF(0, 40));
dataSet.setSelectionShift(5f);

// Outside values
dataSet.setXValuePosition(PieDataSet.ValuePosition.OUTSIDE_SLICE);
dataSet.setYValuePosition(PieDataSet.ValuePosition.OUTSIDE_SLICE);
dataSet.setValueLinePart1OffsetPercentage(100f); /** When valuePosition is OutsideSlice, indicates offset as percentage out of the slice size */
dataSet.setValueLinePart1Length(0.6f); /** When valuePosition is OutsideSlice, indicates length of first half of the line */
dataSet.setValueLinePart2Length(0.6f); /** When valuePosition is OutsideSlice, indicates length of second half of the line */
setExtraOffsets(0.f, 5.f, 0.f, 5.f); // Ofsets of the view chart to prevent outside values being cropped /** Sets extra offsets (around the chart view) to be appended to the auto-calculated offsets.*/

PieData data = new PieData(dataSet);
data.setValueTextSize(10f);
data.setValueTextColor(Color.BLACK);
setData(data);

public static void chart details1(piechart mchart,typeface tf){
mchart.setcentertext(“”);
mchart.setcentertext字体(tf);
麦克哈特.塞特霍尔拉迪厄斯(45F);
图例L=mchart.getLegend();
l.设置方向(图例、图例、方向、水平);
l.setdrawinside(假);
mchart.setextraoffsets(25.f,0.f,25.f,0.f);

mchart.setdrag减速摩擦系数(0.95f);
mchart.setholecolor(彩色、白色);
mchart.settransaparentcirclealpha(110);
McHart.SetTransparentCircleradius(35华氏度);

mchart.setrotationEnabled(错误);



arraylist<integer>colors=new arraylist<integer>();

颜色。添加(c);


颜色。添加(c);


用于(int c:colortemplate.pastel_colors)

colors.add(colortemplate.getholoblue());

}
dataset.setvaluelinepart2length(0.6f);/**当valueposition为outsideslice时,表示行的后半部分的长度*/
data.setvaluetextsize(5f);
data.setValueFormatter(new PercentFormatter());
}


piedataset dataset=new piedataset(entries1,空);
dataset.setcolors(颜色);

实现OnChartValueSelectedListener

    mChart.setTransparentCircleRadius(50f);
    Legend l = mChart.getLegend();
    l.setVerticalAlignment(Legend.LegendVerticalAlignment.TOP);
    l.setHorizontalAlignment(Legend.LegendHorizontalAlignment.RIGHT);
    l.setOrientation(Legend.LegendOrientation.HORIZONTAL);
    l.setWordWrapEnabled(true);
    l.setDrawInside(false);
    mChart.setTouchEnabled(true);
    mChart.setDrawEntryLabels(false);
    mChart.setExtraOffsets(25.f, 0.f, 25.f, 0.f);

    mChart.setUsePercentValues(true);
    mChart.setDragDecelerationFrictionCoef(0.95f);

    mChart.setTransparentCircleRadius(61f);
    mChart.setRotationAngle(0);
    // enable rotation of the chart by touch
    mChart.setHighlightPerTapEnabled(true);
    // mChart.setUnit(" €");
    // mChart.setDrawUnitsInChart(true);
    l.setEnabled(true);
    mChart.highlightValues(null);
    mChart.setUsePercentValues(true);
    /*new*/
    mChart.setHoleRadius(30f);
    mChart.setDrawCenterText(false);
    mChart.setTransparentCircleRadius(35f);

    mChart.getDescription().setEnabled(false);
    mChart.setRotationEnabled(false);

    mChart.setEntryLabelColor(Color.WHITE);
    mChart.setEntryLabelTextSize(9f);

}

添加条目后,添加这些行,

    PieDataSet dataSet = new PieDataSet(entries1, null);
    ArrayList<Integer> colors = Constants.colorsList();
    dataSet.setColors(colors);
    PieData data = Constants.pieDatasetSlice(dataSet);
