EasyChart update is very slow


I’m a beginner with Ignition and I’m having some trouble understanding why my easy chart update is so slow.

Indeed, I’m requesting my EasyChart to display something like 25000 points (it represents the variation of a level of water in a dam, during one year), and it takes more than 12-15 seconds to be displayed.
When I do a SQL query to get the exact same data, it takes like 0.01 seconds to execute, so it’s not the queries that make the display that slow.

Then I suppose that either 25000 points is too much for Ignition to analyze, or maybe the EasyChart component is slow and I shouldn’t use it?

Thank you in advance for your time!
