Creates a new marker for series_data_element for x=series_index. For a timeseries, you can specify the time that you wish to be emphasised.

  • series_data_element (DataElementDecorator) – The DataElementDecorator which should be decorated with an emphasised point.

  • coordinates (Tuple[Any, Any]) – The x and y coordinate of the point that should be emphasised. The x and y coordinates should be expressed in data coordinates (e.g. the x coordinate should be a date if x-axis contains dates).

  • color (str) – color of the marker; by default it will be the same as the decorated line

  • decimal_points (int) – number of decimal points that should be shown in the point’s label

  • label_format (str) – A format string specifying how the label should be displayed. Takes two parameters: the index and value. useful values: ‘ {:0.1E}’, ‘ {:0.1f}’

  • key (str) – see: ChartDecorator.__init__#key

  • use_secondary_axes (bool) – determines whether this PointEmphasis belongs on the secondary axis.

  • move_point (bool) –

  • font_size (int) – size of font
