Hello, I would like to plot vehicle trajectory on a cartesian coordinate system in near-real time from the data that is coming from a datastream. Is it possible to do this in Gadfly. My requirement is to push latest observation to the plot and make the plot update itself. I am looking for someth…

You can do it with GLMakie, for example: using GLMakie GLMakie.activate!() f = Figure() data = Observable([0f0, 1f0]) ax, lin = lines(f[1, 1], data) running = Observable(false) b = Button(f[2, 1], label = @lift($running ? "Stop stream" : "Start stream"), tellwidth = false ) on(b.click…

Thank you the response. I will definitely look into it. One more question, Lets say, I let the code run indefinitely, push the data indefinitely, will I encounter a memory problem? How does makie handle these issues. Do you have any knowledge about it? Does it summarize or smoothe the old data t…

Yes of course, you can’t indefinitely push data into a vector. But you could just as well put some kind of online stats function in between, so that you limit the amount of data you show. That’s not really something that Makie is concerned with, it just shows the data.

Is it possible to overlay plot to a map?

Yes, you can plot whatever you want under the lines
