title: How to set rect bar width to 1 minute in D3JS timescale bar graph
body: <p>I'm new with D3JS and I'm making a zoomable bar graph in a timescale following <a href="https://bl.ocks.org/misanuk/fc39ecc400eed9a3300d807783ef7607" rel="nofollow noreferrer">this example</a>. I changed the circles to rects instead. Now I just can't figure out how can I make it so that the bar width is always 1 minute?</p>
