One of my gripes with the Power Chart is that all data in the time window updates every time the time changes, even slightly, so data points are interpolated each time and end up with different values leading to points jumping up and down each time the time window shifts. Obviously this is super dodgy to an operator trying to look at a trend... e.g. > [@\[FEATURE\] Increase usability of the Perspective Power Chart component](https://forum.inductiveautomation.com/t/feature-increase-usability-of-the-perspective-power-chart-component/51474/23): > > And this is what I meant about displaying sampled being unusable. (the higher you increase the # samples the more stable it is, but this is at default settings) This is server CPU and memory usage. Notice the ups and down change every second, and sometimes large spikes from 30% to 70% and 80% appear and then disappear the next second for the same point in time. Implementing this ourselves we could eliminate this by keeping the data there when time updates. The issue might be with how much we can keep --- _[View the full topic](https://forum.inductiveautomation.com/t/bug-perspective-power-chart-bug-embr-chart-as-a-replacement/102084)._
