# Why does a Calc square root plot have a kink? [closed]

If I make a linear sequence of numbers e.g. from 100 to zero step -10, then take the square root of each number and make a chart of these square roots, it has a kink around 9 and 10. I can't upload an example sorry, but here is the data:

Sequence Sqrt() 100 10 90 9.48683298050514 80 8.94427190999916 70 8.36660026534076 60 7.74596669241483 50 7.07106781186548 40 6.32455532033676 30 5.47722557505166 20 4.47213595499958 10 3.16227766016838 0 0

The chart of the Sqrt() column has a downward kink at 9 on the x axis, followed by an upward kink before 10. Why is this?

Hello David Cheshire, i could not reproduce your problem in Calc Version: 5.1.6.2, plz specify which Chart Type produces the kink
