Task that creates input for Flint plot

Use case in Bliss+Flint (see execute_workflow for what the workflow needs to return):

from time import sleep
import numpy
from bliss.common.plot import get_flint


def execute_workflow():
    return {
        "plot1": {
            "x": numpy.arange(100),
            "y": numpy.random.random(100),
            "xlabel": "Energy (eV)",
            "ylabel": "mu",
        },
        "plot2": {
            "x": numpy.arange(100),
            "y": numpy.random.random(100) + 10,
            "xlabel": "Wavenumber (Å)",
            "ylabel": "k^2 χ(k) (Å^2)",
        },
        "plot3": {
            "x": numpy.arange(100),
            "y": numpy.random.random(100) + 20,
            "xlabel": "Radial Distance (Å)",
            "ylabel": "|χ(R)| (Å^3)",
        },
        "plot4": {
            "x": numpy.arange(100),
            "y": numpy.random.random(100) + 30,
            "xlabel": "Energy (eV)",
            "ylabel": "Noise",
        },
    }

    plots["plot4"] = f.get_plot("curve", unique_name="plot4")

    # loop until the end of the scan (interval of n seconds)
    for i in range(10):
        data = execute_workflow()
        if i == 0:
            prepare_scan_plot(plots, scan, data)
        refresh_scan_plot(plots, data)
