    The width and height are not supported by a line element.

    It seems you should apply a color to this line.

    Thanks this worked for me:

     

                   let sLine = this.g
               .append('g')
               .append('line') 
               .classed('sLine', true)
               .attr('x1', x(0))
               .attr('y1', y(0))
               .attr('x2', x(viewModel.dataMax * this.slopeVal[0]))
               .attr('y2', y(viewModel.dataMax))
               .attr('stroke', 'red');

The line is always rendered at the same position as you use fixed coordinates (.attr('x', x(0)) .attr('y', y(30))).

We'd recommned to use dynamic coordinates instead.
