Realtime

Marple supports visualisations of realtime data!

If a data set is realtime, the realtime metadata field will be True, and a blue checkmark will show in the data library.

To mark that certain data is realtime you will have to set the realtime variable to True when making a connection.

See also Setup and Configuration.

Live mode

If you selected a realtime dataset to visualise, you will notice that the time axis is automatically updated and new data appears. There will also be a 🔴 Live banner in the top left of the screen to show that the data is live.

Refresh rate

By default the refresh rate is set at 1s. To change the refresh rate, simply click on the dropdown button next to the Live banner, and set the desired refresh rate.

Next to the refresh rate, you will see in grey what the maximum view is of data you visualise given the chosen refresh rate.

Disable live mode

To disable the live view realtime data, simply set the refresh rate to None. The live banner will then show the Resume status.

You can now analyse the data from the realtime dataset as any other data set. You resume by selecting a refresh rate other than None.

Easily toggling live mode on and off, and treating the realtime data as any other dataset, is very powerful.
