Why am I receiving an "Overflow" error when using the Autoscale macro command in LabChart?

The error pictured below is due to a known issue in LabChart for Windows version 8.1.8 and earlier with this particular macro command.

This issue will be corrected in a future release of LabChart 8 for Windows.  In the meantime, please change the command's text in your macro script from "Call Doc.AutoScale (kAllChannels, "Chart View")" to "Call Doc.AutoScale (-1, "Chart View")" to work around this issue.

If you require further assistance with this issue, please contact your local ADInstruments Technical Support.
