After upgrading from CitectHMI/SCADA 5.41 Spk B, to CitectHMI/SCADA 5.42, some cicode I wrote is not working as it previously had. Specifically Mode 65 of the Plotopen() function does not seem to allow transparent plots or a history of plots. Each time the Plotopen function is called, it wipes the existing plot, and redraws the new data. Am I doing something wrong? I have also tried all the other Plotopen() modes with no luck. 

Citect has confirmed this to be a problem in CitectHMI/SCADA version 5.42 to 5.50Spk A. We are researching this problem and will post new information here as it becomes available.

A hotfix is available for Citect version 5.50SPA.
