Remove the vertical line in the chart js line chart
The following applies to Chart.js 2.*.
If you only have one x-axis, whether the vertical grid lines (that are related to this x-axis) are displayed or not, is specified by the boolean value of options.scales.xAxes[0].gridLines.display. To be more precise, the following chart options disable the display of vertical grid lines for the single x-axis case.
options : { scales : { xAxes : [ { gridLines : { display : false } } ] }}
There's a new global option that was released with the new version of Chart.js two days ago.
var options = { scaleShowVerticalLines: false}
options : { scales: { yAxes: [{ gridLines: { lineWidth: 0, color: "rgba(255,255,255,0)" } }] } };Charts.js v2.0
