我想在我的 Android 应用程序中显示一个带有工具提示功能的堆积条形图。我使用 MarkerView 显示它但没有成功。这是示例代码。
我也在传奇中面临问题..！由于库不支持文本换行，因此未显示图例。Y 轴的值以整数显示。我想在浮动中显示。我可以在 Y 轴值中给出“%”吗？像这样的东西，
chart1 = (BarChart) findViewById(R.id.chart1);
chart1.setDrawYValues(true);
//chart1.setDrawValueAboveBar(true);
chart1.setDescription("");
chart1.set3DEnabled(false);
chart1.setUnit("%");
chart1.setDrawGridBackground(false);
chart1.setDrawHorizontalGrid(true);
chart1.setValueTextSize(8f);
chart1.setDrawBorder(false);
chart1.setYRange(0.0f,100.0f,true);
chart1.setDrawLegend(true);
chart1.setPinchZoom(true);
chart1.setTouchEnabled(true);
//Code for Tooltip at barchart.
/*MyMarkerView mv = new MyMarkerView(getApplicationContext(), R.layout.custom_marker_view);
mv.setOffsets(-mv.getMeasuredWidth() / 2, -mv.getMeasuredHeight());
chart1.setMarkerView(mv);*/
XLabels xl = chart1.getXLabels();
xl.setPosition(XLabels.XLabelPosition.BOTTOM);
xl.setSpaceBetweenLabels(10);
xl.setCenterXLabelText(true);
YLabels yl = chart1.getYLabels();
//yl.setLabelCount(10);
yl.setPosition(YLabels.YLabelPosition.LEFT);
setData();
Legend l = chart1.getLegend();
l.setPosition(Legend.LegendPosition.BELOW_CHART_RIGHT);
l.setFormSize(8f);
l.setYEntrySpace(4f);
chart1.animateY(3000);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
Toast.makeText(getApplicationContext(), "Error Occurred [Server's JSON response might be invalid]!" + e.getMessage(), Toast.LENGTH_LONG).show();
e.printStackTrace();
}
