Auto-update plot
===================

This demo shows two possibilities of how to create an auto
updating plot, when the data does not come from a device allowing a live plot.

.. GENERATED FROM PYTHON SOURCE LINES 6-12

.. code-block:: Python


    from numpy import random
    import time
    from itom import dataObject
    from itom import plot1








.. GENERATED FROM PYTHON SOURCE LINES 14-18

Option 1: open plot with fixed interval, the plot shares its values
from a given ``dataObject``, update the ``dataObject`` regularly and call
the replot slot of the plot to force an update of the canvas (without that
slot, the canvas is updated once the user makes a zoom, clicks somewhere...)

.. GENERATED FROM PYTHON SOURCE LINES 18-28

.. code-block:: Python

    d = dataObject.zeros([1, 3], "float64")
    [i, h] = plot1(d, properties={"yAxisInterval": (0, 1)})

    t = time.time()
    for i in range(0, 50):
        d[0, :] = random.rand(3)
        h.call("replot")
        time.sleep(0.1)
    print("finished in %.2f s using replot" % (time.time() - t))





.. rst-class:: sphx-glr-script-out

 .. code-block:: none

    finished in 5.16 s using replot




.. GENERATED FROM PYTHON SOURCE LINES 29-33

Option 2: similar to option 1, but the plot is continuously given the same
object again as source. Some caching mechanism provides a quick replot
of the data. This option makes an automatic bounds-check of the new source
and can therefore automatically reset automatic axes intervals

.. GENERATED FROM PYTHON SOURCE LINES 33-41

.. code-block:: Python

    [i, h] = plot1(d)

    t = time.time()
    for i in range(0, 50):
        d[0, :] = random.rand(3)
        h["source"] = d
        time.sleep(0.1)
    print("finished in %.2f s using autoupdate" % (time.time() - t))
