""" Similarly, we can place the legend at any position in the figure by changing the value of the bbox_to_anchor parameter. . Bbox coordinates are interpreted in the coordinate system given by bbox_transform, with the default transform Axes or Figure coordinates, depending on which legend is called. But maybe I am getting something else wrong? I’m going to change some display options so that our map is easier to see, use masking to plot WNV+ and WNV- mosquitoes with different markers, and add labels and a legend: You’ve done it! These positions represent the legend’s position, with respect to the bounding box specified by the bbox_to_anchor parameter..

The value of the loc parameter "upper left" represents the upper left corner of the legend, which is placed at the red dot. Do black holes exist in 1+1 dimensional spacetime? Instead of specifying the legend position in axes coordinates, one may use figure coordinates. Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. To this end, one would use the bbox_transform argument and supply the figure transformation to it. We'll start by just plotting the world dataframe which we loaded above to see results. Ouff sorry I thought I'd looked through the other post carefully, but I hadn't scrolled down far enough to see your answer - thank you, trying to understand this now. How do you change the size of figures drawn with matplotlib? In matplotlib python, the location of axes including subplots, are specified in normalized figure coordinates. Notes.

Matplotlib.pyplot.legend() A legend is an area describing the elements of the graph. But when I say loc="upper right" and give a bbox_to_anchor specification, that bbox_to_anchor specification will be interpreted with respect to the axes and the loc keyword refers to the corner of the legend? In this case it is possible to position the legend inside the plotting area. The default for loc is loc="best" which gives unpredictable results when the bbox_to_anchor argument is used. As far as geo mapping goes Matplotlib and Plotly look different (sometimes better) from the canonical Google Maps visual. Thanks - I've edited it. The bbox_to_anchor parameter takes a tuple, representing the coordinate, where the corner specified by the loc parameter will be placed. Below is an example where the bounding box is set to position (0.6,0.5) (green dot) and different loc parameters are tested. The subplot at the bottom, the bbox_to_anchor is set to (0.6,0.4) marked by the red dot on the figure’s bottom axes.

And the instances of Axes supports callbacks through a callbacks attribute. Sorry - how to the bbox_to_anchor and loc keywords interact? x and y are the coordinates of the legend box. According to the matplotlib legend documentation: The location can also be a 2-tuple giving the coordinates of the lower-left corner of the legend in axes coordinates (in which case bbox_to_anchor will be ignored). I’ve given all three of these libraries a pretty fair shake, and of the three I prefer using Bokeh with Google Maps because it’s so familiar and so simple to plot anything with latitude and longitude data. https://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.legend. If a 4-tuple or BboxBase is given, then it specifies the bbox (x, y, width, height) that the legend is placed in.
