The series-interpolate is the effect of the animation which interploate from the start value of the Y-axis (or X-axis) to the data value.

The <SeriesInterpolate> element tag is used to create the series-interpolate effect in the chart, and it must be defined as a child node of the <showDataEffect> element tag which is a child node of the series nodes, such as <Column2DSeries>, <Bar2DSeries>, etc.

  <showDataEffect>
    <SeriesInterpolate duration="1200" elementOffset="60"/>
  </showDataEffect>

</Column2DSeries>

duration The duration attribute controls the total effect time (unit: millisecon, default : 500 ms).
elementOffset The elementOffset attribute controls the delay between the two adjacent data elements (unit: millisecon, default : 20 ms).
