draw circles

All the dots/circles of the graph are set thru this function. You cannot name the groups as for the curves.

drawCircles(dots, opts)

• dots: a array of dot structures like this:

  • id: a unique ID for the dot. It is optional. id is useful for transitions, recalls to ensure each circle is affected to the same business dot.

  • x: the x position of the dot (date)

  • y: the y position of the dot (date)

  • title: the tooltip of the dot (text)

  • color: the color of the dot (string). can also be a function where the parameter is the dot. the return should be a web color or a hex value

  • radius: the size of the circle of the dot (string). can also be a function where the parameter is the dot. the return should be a number

  • opacity: the opacity of the circle of the dot (string). can also be a function where the parameter is the dot. the return should be a number between 0 and 1

• opts: the default values if they are not specified in each dot.

  • autoScaleX: The X axis is recomputed to match the data.

  • autoScaleY: The Y axis is recomputed to match the data.

  • color: the color of the dot (string). can also be a function where the parameter is the dot. the return should be a web color or a hex value

  • radius: the size of the circle of the dot (string). can also be a function where the parameter is the dot. the return should be a number

  • opacity: the opacity of the circle of the dot (string). can also be a function where the parameter is the dot. the return should be a number between 0 and 1

  • stack: the y value is ignored and the dots are piled up in case they overlap
