**Setting colors:**
Setting colors can be done via the <code>ColorTemplate</code> class that already comes with some predefined colors (constants of the template e.g. <code>ColorTemplate.LIBERTY_COLORS</code>). In our example case, we want one color for each <code>DataSet</code> (red and green):
Setting colors can be done via the <code>ColorTemplate</code> class that already comes with some predefined colors (constants of the template e.g. <code>ColorTemplate.LIBERTY_COLORS</code>).
Explaination: The <code>ColorTemplate</code> basically has two methods for setting colors:
- <code>addDataSetColors(int[] colors, Context c)</code>: This method will add a new array of colors for the <code>DataSet</code> at the current index. The current index starts at 0 and depends counts up per call of this method. If no calls of this method have been done before, the colors set in this call will be used for the <code>DataSet</code> at index 0 in the <code>ChartData</code> object. Upon calling this method again on the same <code>ColorTemplate</code> object, the provided color values will be used for the <code>DataSet</code> at index 1.
- <code>addColorsForDataSets(int[] colors, Context c)</code>: This method will spread the provided color values over an equal amount of <code>DataSet</code> objects, using only one color per <code>DataSet</code>.
In our example case, we want one color for each <code>DataSet</code> (red and green):
```java
ColorTemplate ct = new ColorTemplate();
ct.addColorsForDataSets(new int[] { R.color.red, R.color.green }, this);
