Add vertical bar

[danielecook]

Is there a way to add a vertical bar across all tracks?

a vertical bar? Can you give me a quick sketch to give me an idea what you are looking for?

I wrote a simple implementation here (having never used Canvas, and which is not integrated into the library...):

// Get canvas object. Provide a start (first vertical line) and an end (second vertical line)
   var boundary = document.getElementById("gene_glyph").getContext("2d");
    // Start
    boundary.beginPath();
    boundary.moveTo(glyph.pixelsToNts(start) + glyph.offset - glyph.pixelsToNts(glyph.scale.min), 15);
    boundary.lineTo(glyph.pixelsToNts(start) + glyph.offset - glyph.pixelsToNts(glyph.scale.min), 1000);
    boundary.strokeStyle = "Blue";
    boundary.stroke();
    // End
    boundary.beginPath();
    boundary.moveTo(glyph.pixelsToNts(end) + glyph.offset - glyph.pixelsToNts(glyph.scale.min), 15);
    boundary.lineTo(glyph.pixelsToNts(end) + glyph.offset - glyph.pixelsToNts(glyph.scale.min), 1000);
    boundary.strokeStyle = "Blue";
    boundary.stroke();

I'm sure there is a cleaner way. I think an ideal method would be invoked like this:

// Canvas is a scribl object
canvas.vertical(nt_pos, stroke, color, etc.)

I essentially want to use this for marking, for example, the start and end of an interval that a user inputs to search on.

By the way, this is a great library!
