title: Unable to set color for BarChart in MPAndroidChart
body: <p>I want to set a specific color for a bar in <code>BarChart</code> from <code>MPAndroidChart</code>. I do everything according to a documentation, but the color isn't changing.
  Here's my code:</p>
  
  <pre><code>   barChart = (BarChart) findViewById(R.id.bar_chart);
     List&lt;BarEntry&gt; entries = new ArrayList&lt;BarEntry&gt;();
     entries.add(new BarEntry(1.0f, 10.0f)); //tmp values
  
     BarDataSet dataSet = new BarDataSet(entries, "bars");
     dataSet.setColor(R.color.red); //color from resourses
  
     BarData barData = new BarData(dataSet);
  
     barChart.setData(barData);
     barChart.invalidate(); 
  </code></pre>
  
  <p>The funny thing is that before I tried to change the color of the bar, the bar was blue, after I tried to change its color, it became grey (no matter, what color it must be). I don't understand why doesn't the color change.
  I also tried to override <code>getColor</code> method in the <code>BarDataSet</code> class, but result is the same -- bar is grey.</p>
