Hi,

Hopefully I can help answer your question below here:

1. Overview of Streaming

This is a very useful video about how Streaming queries are set up : KX Dashboards | Streaming Data – YouTube

2. Demo Streaming with Filtering

If you have KX Dashboards installed (https://code.kx.com/dashboards/gettingstarted/)

Then navigate to the “Demo Stream” Dashboard, there is a build in example where we pass in a parameter to the streaming model that filters the returning data set .

Therefore:

1. On load – we subscribe to the using the default filter

2. If we change the viewstate, we then unsubscribe and the re-subscribe using the new filter

In the current map solution we are just tracking the altitude value at present

There are couple things here that you could do to demonstrate altitude

1) You could use a data-driven line gradient – this would color the line based on the current altitude

2)You could use a secondary chart to show the altitude

If you need anymore details here just let me know

Regard
