5.x _AdvisingScreen.php	_AdvisingScreen::draw_pie_chart_box($title, $top_value, $bottom_value, $pal = "", $back_col = "", $fore_col = "", $extra = "")

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. If set, fore_col will be ignored in the argument list.
• Acceptable values:
  • core
  • major
  • cumulative
  • student

string $back_col:

• If $pal is left blank, the value here will be used for the "back" or "unfinished" color.

string $fore_col:

• If $pal is left blank, the value here will be used for the "foreground" or "progress" color.

Return value
