Formatting data labels in a pie chart with just a few slices is a no-brainer, but what if it contains lots of categories? Even though we could use leader line option to display individual labels more clearly, it still doesn’t look professional.

By manually drawing leader lines, we can make the pie chart more presentable. It is quite time consuming in fact but well worth the effort. Let’s begin.

• First we need to spread out the labels and leave some space for the leader lines

• Use straight or perpendicular lines to pinpoint all the labels, and make sure all lines are consistently
  pointing towards either category labels or values, depending on position.  Of course, if you decided
  use legend, then there is no need to worry about that

• When all lines are drawn, take a look and see if anything needs to be fine tuned
