XY Graphs - Hard Coded Limit of 10000 Events
If in the XY graph there are traces with a point every minute and a user selects the standard interval "1W", nothing is shown.
There’s an explanation already present in the knowledge base in the last paragraph of the link: https://customers.osisoft.com/s/knowledgearticle?knowledgeArticleUrl=Errortoomanypointsindataset : “Starting in PI Vision 2019 XY plots have a hard coded limit of 10,000 events "
The combination of a point every minute and “1W” requires 10080 events per track (the number of minutes in a week), so over the limit of 80 events.
Rather unpleasant that it happens on the value "1W" which is one of those proposed by default by PiVision: easy to explain to users that "1mo" is too much, a little less than "1w" is not good but at most "6d22h40m" is acceptable (corresponding to the limit of 10000 events per trace).
The request / suggestion is to bring the limit to 10080. The 0.8% increase shouldn't affect the performance (the value of 10000 looks like a round figure).

Thanks for the proposal. I would even suggest to have the parameter manually adjustable by an IS responsible (and not hard coded as it is now).
