Vertical Lines

Vertical (or horizontal in case of bar charts) separator lines or vlines are elements that can help differentiate between data blocks in a chart. They can be placed between any two data points, or aligned to specific data points.

Vertical lines

Set Vertical Lines

By default, the vertical lines do not appear. To display a vertical line follow the steps below:

  • Create an object under data between the data values where you want to render the vertical line.

  • Set the vLine attribute to 1.

  • Set the value of showOnTop attribute to 1.

  • Specify the display text of the vertical line using the label attribute.

  • Set the position of the vertical line using the linePosition attribute.

Refer to the code below:

{
    "chart": {
       ...
    },
    "data": [{
        "label": "Fri",
        "value": "5529"
    },
    {
        "vLine": "true",
        "showOnTop": "1",
        "label": "Weekend Start",
        "linePosition": "0.7"
    },
    {
        "label": "Sat",
        "value": "5803"
    },
    {
        "label": "Sun",
        "value": "6202"

    "chart": {
        ...
    },
    "data": [{
        "label": "Fri",
        "value": "5529"
    },
    {
        "vline": "true",
        "showOnTop": "1",
        "label": "Weekend Start",
        "linePosition": "0.7",
        "labelPosition": "0.5",
        "labelVAlign": "middle",
        "labelHAlign": "right",
        "showLabelBorder": "1"
    },
    {
        "label": "Sat",
