Formatting the Legend Title

Syntax: How to Format the Legend Title

"legend":
  {
   "title": 
   {
      "visible": boolean,
      "text": "string",
      "font": "string",
      "color": "string"
      "tooltip": "string",
      "wrap": number
   }
 }

where:

"visible": boolean

Can be:

true, which makes the legend title visible.
false, which makes the legend title not visible. This is the default value.
"auto", which lets the chart engine determine legend visibility and placement.

"text": "string"

Is a string that defines the legend title text. The default value is "Legend Title".

"font": "string"

Is a string that defines the size, style, and typeface of the legend title. The default value is "10pt Sans-Serif".

"color": "string"

Is a string that defines the color of the legend title using a color name or numeric specification string. The default value is "black".

For information about defining colors, see Colors and Gradients.

"tooltip": "string"

Is a string, or a function that returns a string, to display when the mouse hovers over the legend title.

"wrap": number

Defines the number of lines for wrapping long titles. Can be an integer, which wraps long labels to that number of lines (if necessary), or "auto", which wraps long titles into as many lines as necessary. The default value is 1.
