This function is used to draw an individual pie chart box. It accepts values of top/bottom in order to come up with a percentage.

Parameters

string $title:

float $top_value:

• The top part of a ratio. Ex: for 1/2, $top_value = 1.

float $bottom_value:

• The bottom part of a ratio. For 1/2, $bottom_value = 2.
• Do not let this equal zero. If it does, the calculation for the pie chart will never be evaluated.

string $pal:

• Which palette to use for the pie chart.
• Acceptable values:
  • core
