Online chart widget: "pause" data recording

Hi
We are currently using OnlineCharts in mappView to display process data. Is there an easy way to “freeze” the current chart for better analysis? We were thinking of a “pause” button or something similar. While we could implement this using the LineChart widget, it’s not a viable option due to the necessary software changes required for the data arrays.

We are looking to implement a simple “scope” for predefined variables, as mappCockpit is not very user-friendly for our technicians. Additionally, it’s often difficult to access the machines due to the IT policies of our customers.

Hi,
you prop. might want to look into the OnlineChartHDA … While this widgets is intended to be used with OPC-UA HDA functionality, it behaves pretty much similar to the OnlineChart, if no HDA is configured. OnlineChartHDA however has a “freeze” function to better analyse the data.
