# Load the license key

# Adding a Pitchfork
pitchfork = chart.add_pitchfork(9, 207, 78, 257, 89, 233)
pitchfork.set_magnetic(True)
pitchfork.set_area_color('#20200020')

# Adding Fibonacci Arc
chart.add_fibonacci_arc(363, 240, 355, 273)

# Adding a down arrow
down_arrow = chart.add_arrow(224, 342)
down_arrow.set_arrow_type('DownArrow')

# Adding an additional arrow
chart.add_arrow(464, 211)

# Adding a text box
text_box = chart.add_text_box(
    400, 340, 'Drawing tools can also be added via the toolbar on the left.'
)
text_box.set_fill_color('#20201010')
text_box.set_border_width(0.5)
text_box.set_border_color('#ffff20')

# Adding plain text
plaintext = chart.add_text_box(65, 284, 'Right-click a control point, arrow, or text')
plaintext.set_font_size(18)
plaintext.set_text_color('#ddffdd')

plaintext2 = chart.add_text_box(65, 278, 'to modify the tool.')
plaintext2.set_font_size(18)
plaintext2.set_text_color('#ddffdd')
