    # These 2 calls are superflous and does nothing
    # It was an attempt to draw borders for the chart which did not work for indicator charts

    # Dont tell anyone that I was this stupid!

NOTE: The last 2 calls to "update_axes" and "update_yaxes" were intended to draw borderlines for the chart. However, since Indicator charts do not have axes, they don't take any effect. These 2 calls can simply be removed.
