add_text

Plotter.add_text(text, position='upper_left', font_size=18, color=None, font=None, shadow=False, name=None, viewport=False)

Add text to plot object in the top left corner by default.

Parameters

textstr

The text to add the rendering.

positionstr, tuple(float), optional

Position to place the bottom left corner of the text box. If tuple is used, the position of the text uses the pixel coordinate system (default). In this case, it returns a more general vtkOpenGLTextActor. If string name is used, it returns a vtkCornerAnnotation object normally used for fixed labels (like title or xlabel). Default is to find the top left corner of the rendering window and place text box up there. Available position: 'lower_left', 'lower_right', 'upper_left', 'upper_right', 'lower_edge', 'upper_edge', 'right_edge', and 'left_edge'.

font_sizefloat, optional

Sets the size of the title font. Defaults to 18.

colorstr or sequence, optional

Either a string, RGB list, or hex color string. For example:

• color='white'

• color='w'

• color=[1, 1, 1]

• color='#FFFFFF'

Defaults to pyvista.global_theme.font.color.

fontstr, optional

Font name may be 'courier', 'times', or 'arial'.

shadowbool, optional

Adds a black shadow to the text. Defaults to False.

namestr, optional

The name for the added actor so that it can be easily updated. If an actor of this name already exists in the rendering window, it will be replaced by the new actor.

viewportbool, optional

If True and position is a tuple of float, uses the normalized viewport coordinate system (values between 0.0 and 1.0 and support for HiDPI).

Returns

vtk.vtkTextActor

Text actor added to plot.

Examples

>>> import pyvista
>>> pl = pyvista.Plotter()
>>> actor = pl.add_text('Sample Text', position='upper_right', color='blue',
...                     shadow=True, font_size=26)
>>> pl.show()
