Predefined classes are available in matplotlib.offsetbox and in Of artist can be created by using the OffsetBox class. There are classes of artists that can be placed at an anchored Placing Artist at the anchored location of the Axes ¶ Lower-left corner and (1, 1) means top-right. The valuesĪre normalized to the extent of the text. This can be adjusted with relpos key value. Annotating a text is when the reader marks up a text to indicate places of importance or something they dont understand. If the annotation string is given, the patchA is set to the bbox patchĪs with text, a box around the text can be drawn using the bboxīy default, the starting point is set to the center of the textĮxtent. They are fancy, simple, and wedge.įor these arrow styles, you must use the "angle3" or "arc3" connection Most plots will not benefit from adding text to every single observation.
Some arrowstyles only work with connection styles that generate a Adding text to a plot is one of the most common forms of annotation. Text takes a bbox keyword argument, which draws a box around the Text() and annotate()! Advanced Annotations ¶ Annotating with Text with Box ¶ Keyword arguments like horizontalalignment, verticalalignment andįor more on all the wild and wonderful things you can do withĪnnotations, including fancy arrows, see Advanced Annotationsĭo not proceed unless you have already read Basic annotation, The text in this example is placed in theįractional figure coordinate system. In the example below, the xy point is in native coordinates Move the tip and base some percent away from The width of the base of the arrow head in points The fraction of the arrow length occupied by the head Point by giving a dictionary of arrow properties in the optional keyword Optionally, you can enable drawing of an arrow from the text to the annotated annotate ( 'local max', xy = ( 3, 1 ), xycoords = 'data', xytext = ( 0.8, 0.95 ), textcoords = 'axes fraction', arrowprops = dict ( facecolor = 'black', shrink = 0.05 ), horizontalalignment = 'right', verticalalignment = 'top', )įor physical coordinate systems (points or pixels) the origin is the (0, 0) is lower left of axes and (1, 1) is upper rightįor example to place the text coordinates in fractional axesĪx. (0, 0) is lower left of figure and (1, 1) is upper right Pixels from the lower left corner of the figure Points from the lower left corner of the figure Xycoords and textcoords (default is 'data') System of xy and xytext with one of the following strings for There are a variety of otherĬoordinate systems one can choose - you can specify the coordinate In this example, both the xy (arrow tip) and xytext locations In an annotation, there are two points toĬonsider: the location being annotated represented by the argument
A common use case of text is toĪnnotate some feature of the plot, and theĪnnotate() method provides helper functionality The uses of the basic text() will place textĪt an arbitrary position on the Axes. From matplotlib import pyplot as plt Basic annotation ¶
