• Specify the hex code of for the divisional line color using the vDivLineColor attribute.

• Set the thickness (in pixels) using the vDivLineThickness attribute.

• Set the transparency of the using the vDivLineAlpha attribute.

Refer to the code below:

{
    "chart": {
        "numVDivLines": "5",
        "vDivLineColor": "#99ccff",
        "vDivLineThickness": "1",
        "vDivLineAlpha": "50"
    }
}

Dashed Divisional Lines

You can also render div lines as dashed lines instead of the default continuous lines. To do so, use the following attributes:

• Set the length of each dashed line using the vDivLineDashLen attribute.

• Set the gap between each dash using the vDivLineDashGap attribute.

Refer to the code below:

{
    "chart": {
        "numVDivLines": "5",
        "vDivLineColor": "#99ccff",
        "vDivLineThickness": "1",
        "vDivLineAlpha": "70",
        "vDivLineDashed": "1",
        "vDivLineDashLen": "5",
        "vDivLineDashGap": "3"
   }
}
