Remote controlled batch loading

[TheOtherMarcus]

I am trying to figure out if it is possible to remote control the loading of logged time series data. I want to do the same thing the CSV plugin does, but over websockets or similar channel. Any ideas?

When I stream with websockets, which variable is by default used as the x-axis? Does PlotJuggler measure the time or does it use a time variable found in the data?

Edit 1:
After some experimentation with websockets I see that it basically does what I want. What is missing is

• an infinite buffer. 999 seconds is enough in most of my cases, but sometimes not.
• the ability to command "delete points" over the socket.
• the ability to command the load of a layout over the socket.

There is a bug in the websocket dialog where "bson" is preselected but the fields to select which variable to use as time is not shown. "bson" has to be selected explicitly for the dialog to show the correct fields.

Edit 2:
I should be able to use function(tracker_time) to "delete points" and start over with a clean slate.

• Is there a Lua function that deletes all points in all series?
• Is there a way to iterate over all series? Then I could use series:clear().
• Is there a Lua function to load a layout?

Edit 3:
It seems I can iterate over all series with GetSeriesNames() and TimeseriesView.find(), but the clear() method is not defined on series returned by find(), only newly created series. Why is that so? Just an omission?
