Online Chart widget doesn't work in background

Hello guys,

We need an online chart that works in the background during a machine cycle so we can monitor the temperatures during the current one; using online chart or online HDA chart does not work if the content with the widget is not opened or currently active; as soon as the content is loaded we can see that the chart buffer hasn’t saved the data and starts just when it is loaded. I couldn’t find any option or anything to make it work.

Thank you in advance

Historical and online data you can see using OnlineChartHDA widget
