[ISS Support Case] SA_Trend Graphic Data Reset

Description

I'm trying to test out the Stock Situational Awareness graphic "SA_Trend_MultiPen". I've got a functionality question regarding changing the time period live. I've added this graphic to my application and opened it's configuration. I've set 4 tank level tags and can see trend lines. I am not looking at a historian, but the local computer for log files. There is a down arrow button at the top left of the grid, which when pressed, allows the user to pick a different X-axis timespan. However, my problem here is that when I choose a different timespan, the data resets. So if it's defaulted to 1 min or 5 mins and the operator is having an issue he wants to review, he might want to choose a 1-hour time span. However, all that is erased with the change, and the data starts over. I get that this isn't a Historical Trend, but surely that data shouldn't be overwritten until window viewer is restarted.
