title: How to set x-axis ticks at the left of each bar with echarts library?
body: <p>I want to show each x-axis tick at the left of the bar, not at the center, but I'm not sure which setting can help me with this, I tried setting the <code>boundaryGap</code> to false, but no luck. Please notice the x-axis type is <code>time</code>.
