Different Point counts between two series

[Pat.Knoll]

I have a datatable with 3 columns

1. String called SeriesFields

2. Double called Field1

3. DateTime called SampleDate

I add 25 rows to the datatable

The first twelve rows have a string value of "A"

The remaining thirteen rows have a string vlaue of "B"

I then use the cross tab tool to create two series  of data and map the fields.

So now i have two series with different counts.

The grid shows the missing values at the end or right side and the for Series B that has more points the line chart draws a line from the 12th point back to the first point.
