Is it possible to change the line stroke of markings? I already know that is possible to change the color of it:
markings: [ { yaxis: { from: 0, to: 0 }, color: "#000"},
{ xaxis: { from: 0, to: 0 }, color: "#000" }],
I've used this solution to make my axis without the background grid line: display-x-axis-and-y-axis-lines-with-out-the-grid-lines-using-flot
Just add the option:
markings: [ { yaxis: { from: 0, to: 0 }, color: "#000"},
{ xaxis: { from: 0, to: 0 }, color: "#000" }],
markingsLineWidth: 2.5, //number
