No it has nothing to do with models. They are on different models. We even have some other charts that are on a different page in other part of the screen and those refresh too. It’s something with highcharts, that it redraws the charts whenever a page include loads. It may only be a v1 problem. I remember discussing this with Rob a couple years ago but couldn’t find that in the community and don’t remember the resolution.
In the screenshot below, both the donut charts and and the column charts refresh whenever the page include loads
