I am trying to create a line graph, wherein if all the values for the particular series is zero then, I want the line to be drawn on the bottom over the x-axis line. But it seems like the line of the x-axis takes the preference than the series line. Is there any way to change that?
Below is my configuration:
xAxis: {
type: "datetime",
tickmarkPlacement: "on",
lineWidth: 10,
lineColor: 'red',
},
yAxis: {
min: 0,
minRange : 0.1,
title: {
text: ""
}
},
plotOptions: {
line: {
softThreshold: false
}
},

In the above example the axis line color is red and series line color is black. but red takes the preference. I want the black line to take the preference while displaying
It is not possible to move a series line above an axis line by options in Highcharts API. As a solution, you can use the Highcharts.SVGRenderer class and draw a custom line at the chart bottom.
chart: {
...,
events: {
render: function() {
const chart = this;
const x1 = chart.plotLeft;
const x2 = x1 + chart.plotWidth;
const y = chart.plotTop + chart.plotHeight;
if (!chart.customLine) {
chart.customLine = chart.renderer
.path().attr({
stroke: 'red',
'stroke-width': 10
}).add();
}
chart.customLine.attr({
d: ['M', x1, y, 'L', x2, y]
});
}
}
}
