Scatter Plot with Plotly

I cannot manage to load data in a format that it is suitable for a scatter plot with plotly.
What kind of columns do I have to proivide from a mysql data source?
NamePoint1 10,50
NamePoint2 11,51
NamePoint3 9,40
NamePoint4 11,49

or in 3 different columns?
NamePoint1 10 50

Why do I need the time?

Thanks Helmuth
