title: MPAndroidChart Bar Shadows hides the actual bars
body: <p>I'm using the combined chart to draw stacked bars and a line chart on top of it.
  When I set the bar shadow to true, some of the bars are hidden.
  This is the code I have with bar shadow set to true.</p>
  
  <pre><code>public void setupChart(CombinedChart combinedChart)
  {
  
      combinedChart.setDrawOrder(new CombinedChart.DrawOrder[]{CombinedChart.DrawOrder.BAR, CombinedChart.DrawOrder.LINE});
      combinedChart.setNoDataText("");
      combinedChart.setNoDataTextDescription("");
      combinedChart.setDescription(null);
      combinedChart.setDrawGridBackground(false);
      combinedChart.setDrawBarShadow(true);
      combinedChart.setBackgroundColor(getResources().getColor(R.color.transparent));
  
      XAxisValueFormatter customX=new MyXAxisValueFormatter();
  
      XAxis xAxis=combinedChart.getXAxis();
      xAxis.setPosition(XAxis.XAxisPosition.BOTTOM);
      xAxis.setDrawAxisLine(false);
      xAxis.setDrawLabels(true);
      xAxis.setDrawGridLines(false);
      xAxis.setGridColor(getResources().getColor(R.color.Gray));
      xAxis.setValueFormatter(customX);
      xAxis.setSpaceBetweenLabels(2);
  
      YAxisValueFormatter customY=new MyYAxisValueFormatter();
  
      YAxis leftAxis=combinedChart.getAxisLeft();
      leftAxis.setLabelCount(4, false);
      leftAxis.setDrawAxisLine(false);
      leftAxis.setDrawGridLines(false);
      leftAxis.setValueFormatter(customY);
      leftAxis.setPosition(YAxis.YAxisLabelPosition.OUTSIDE_CHART);
      leftAxis.setSpaceTop(15f);
  
      YAxis rightAxis=combinedChart.getAxisRight();
      rightAxis.setEnabled(false);
  
      combinedChart.getLegend().setEnabled(false);
  }
  </code></pre>
  
  <p>And I get the following chart </p>

  <p>The same code with bar shadow set to false</p>
  
  <pre><code>combinedChart.setDrawBarShadow(false);
  </code></pre>
  
  <p>produces the following chart with the bars right as expected.</p>

  <p>Am i doing anything out of order here ?</p>
  
  <p>If it's a bug which I hope not, can i achieve the bar shadows using the grid lines ?</p>
  
  <p>Great library nevertheless. </p>
