I have an array of strings. Say,
['Jan 11','Feb 11']
And i am creating a vertical text with these string like so
<text x="60" y="154" text-anchor="middle" style="text-anchor: middle; font: normal normal normal 12px/normal Helvetica, Arial; " font="12px Helvetica, Arial" stroke="none" fill="#ffffff" transform="rotate(90 59.75 150)">
<tspan>Jan 11</tspan>
</text>
After the svg has been rendered i find that the height of the text is 36px. Now is there a way to calculate the height of a text that will be rendered beforehand given the font-size?
You can use getBBox
method to calculate dimensions of the SVG nodes.
var textNode = document.getElementsByTagName('text'),
bbox = textNode.getBBox();
//bbox now have x, y, width and height properties
