text can also be used for simple text annotation, but does not provide as much flexibility in positioning and styling as annotate. Not sure how if this has to do with coordinate systems. Axes.annotate also provides an optional arrow from the text to the data and this arrow can be styled in various ways. Point shapes, colors and size Add text annotations to a graph Line types. X_value: 0.6, window_extent_width: 56.0, new_x_position: -27.4 Main title, axis labels and legend title Legend position and appearance. Print "x_value: ".format(x_values, text_window_extent.width, new_x_position)īut as you can see here from print statements the widths are too big: x_value: 0.3, window_extent_width: 31.5, new_x_position: -15.45 Text_t_position((new_x_position, y_values)) New_x_position = x_values - text_window_extent.width / 2 Text_window_extent = text_object.get_window_extent(renderer) I've tried getting the window extent around the text boxes, grabbing the x coordinate and width, and shifting over for each annotation like so: for i, label in enumerate(labels): and make it produce something like this plot: Both of these arguments are (x, y) tuples. In an annotation, there are two points to consider: the location being annotated represented by the argument xy and the location of the text xytext. Plt.savefig("horizontally_centered_text_annotations.png") A common use case of text is to annotate some feature of the plot, and the annotate() method provides helper functionality to make annotations easy. Text_object = plt.annotate(label, xy=(x_values, y_values)) If it is "False", it will draw.I'd like to take something like this code for scatter plot annotations. If you pass it "True" it will not draw when the xy point is outside the plot. It will take the Boolean value, and this will tell when the annotation point xy is outside the axis area whether you want to draw the annotation. annotation_clip The annotation_clip is also an optional parameter. This dictionary argument has several keys so read the detailed documentation from here. Add the text s to the Axes at location x, y in data coordinates. It is optional if you do not mention that it will not add any arrow over the plot. This argument takes the dictionary as a value, so we need to pass it key-value pair. It is also possible to place text relative to the axes coordinates, but this is easier with the annotate command rather than the text command: In 4: fig, ax plt.subplots() ax.annotate('0.25 on axes', (0.25, 0.25), textcoords'axes fraction', size20) ax.annotate('0.25 on data', (0.25, 0.25), textcoords'data', size20) ax.setylim(0, 0. arrowprops Add an arrow between the text and the point that is the annotated point or position. If we want to change the coordinate system of the textcoords parameter, then we can change this parameter. We can change the coordinate system of XY using this parameter.īy default, this annotate() method will take the coordinate system as "data". xycoords, textcoords We can use xycoords and textcoords, which take the coordinate system for XY and text. If you do not mention this, it will take the second xy parameter as the position for the text. xytext The xytext parameter will give you the position where you want to annotate, so this is the optional parameter. The output is as follows: Figure 5.8 Plot displaying Matplotlib text annotations The (.) method provides more control over the. One option is to rotate the text/annotation, which is set by the rotation keyword/property. *args, **kwargs These keyword arguments help us to change the text properties like font style, font size, etc. You need to mention the x coordinate and y coordinate, and this is the point where you want to annotate the points. This resource specifies the minimum amount of space between the reference vector annotation arrow and the text on either side in units of the reference. xy The next is the xy parameter coordinates that accept a tuple and will take the float value. Parameters Description s The first parameter is a text you want to add to the plot.
