I am trying to get a sense of how many data points tag historian is collecting since our database easily becomes 500 mb in less than a month, and I tried using the Powerchart scatter plot to visualize this. It looks like I am collecting multiple points every second, but my tag historian database does not reflect this when I run a SQL query to count how many entries there are for each tag. How do I get the scatter plot to not show data points that were never collected? Or are they really getting logged that quickly?
