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.
... <Column2DSeries ... > ''' <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).|
