Is there a way to draw a perfectly vertical line in QGIS's Composer. I wanted to created a visual separator between two elements for aesthetic reasons.

I've tried the arrow tool, removing the arrow head and holding the shift / ctrl / alt buttons to see if it will lock it to horizontal or vertical angle but no luck.

The only other alternative I could think of was making and importing an SVG, but I wanted to check here first, as that seemed a bit ridiculous.

Thanks for the help

Draw an arrow and remove its end markers. Then, in the item properties panel for the arrow, expand out the "position and size" group. Set the line's width to 0 for a perfectly vertical line, or the height to 0 for a horizontal line.

Edit: QGIS 2.5 now allows you to draw a horizontal or vertical line by holding shift while drawing the line.

Along with changing the arrow head, you can set its rotation (shown in the image) to 90 degrees which would give you a perfectly straight vertical line.

  • Hi Joseph - thanks for the reply. Perhaps I'm being a bit over the top, but the 90 degrees would be from the initial position I thought? This would mean if the initial position were slightly wonky so to would the 90-degree-rotated-line? I thought there was an obvious was to snap to perfect horizontals and verticals that I was missing but perhaps there isn't =/ Thanks – user113904 Jul 3 '14 at 15:56
