Change left bar thickness and color on charts.js line chart

Question

Unless I'm mistake, this appears to be undocumented. Does anyone know if the far left bar colour on line charts can be changed?

It seems the first left bar is always darker than the grid lines.

Answer 1

you need zeroLineColor https://www.chartjs.org/docs/2.8.0/axes/styling.html?h=zerolinecolor

 options = { scales: { xAxes: [{ gridLines: { zeroLineColor: '#fff' }, } ]}}

ChartJS. Change axis line color
