https://jsfiddle.net/betasquirrel/pnyn7vzj/1/ showcases the method for adding horizontal lines along the y axis in this plunkr.
I attempted to implement the following CSS code:
.axis path,
.axis line {
fill: none;
stroke: #000;
}
I am looking to create a bar graph without the x axis. I have included an image for reference. Please see here.
