+# Element: ComboPoints
+
+Handles the visibility and updating of the player's combo points.
+
+## Widget
+
+ComboPoints - An `table` consisting of as many Textures as the theoretical maximum return of [GetComboPoints](http://wowprogramming.com/docs/api/GetComboPoints).
+
+## Notes
+
+A default texture will be applied if the widget is a Texture and doesn't have a texture or a color set.
+
+## Examples
+
+    local ComboPoints = {}
+    for index = 1, 10 do
+        local Bar = CreateFrame('StatusBar', nil, self)
+
+        -- Position and size.
+        Bar:SetSize(16, 16)
+        Bar:SetPoint('TOPLEFT', self, 'BOTTOMLEFT', (index - 1) * Bar:GetWidth(), 0)
+
+        ComboPoints[index] = Bar
