I have a worksheet with a group of sparkline charts, two rows of which use identical values in every cell in their data ranges, yet they show two types of errors

  • A sudden step change in values
  • A random change in values

All the other sparklines in the group have constantly varying data which is represented accurately.

It doesn't make a difference if I create them as a group or individually, in Office Online or the desktop client (2013)

 

Anyone got any idea of what's going on?

That could be rounding error if values are calculatable. In any case it's better to check sample file.
