C3 Js -- how to set X-Axis position .

Hi , is there any way to set X Axis position . my X-Axis values start from negative to positive and i want to set X-Axis to zero instead of bottom. i have used transition method as a work around but with this it gives some delay and we could see X-Axis going from bottom to zero position

d3.select(chart.element).select('.' + c3.chart.internal.fn.CLASS.axisX).transition()
.attr('transform', "translate(" + 0 + "," + chart.internal.y(0) + ")");

Start by reproducing the chart with X-axis values spanning negative and positive numbers, then trace the chart.element selection and CLASS.axisX transform shown in the workaround. Check the axis-rendering entry point and existing axis-position configuration. Done means the X-axis renders at the zero value without a transition delay and existing axis behavior remains intact.
