![]() Here, we added the y-axis value of the point as its label for each point on the scatter plot. Plt.text(xi, yi, yi, va='bottom', ha='center') To label each point on the scatter plot, use the () function for each point in the plot. Example 2 – Label Each Point on the Scatter Plot Here, we used the va parameter to set the vertical alignment of the text to ‘center’ and the ha parameter to set the horizontal alignment to ‘center’ as well. ![]() For example, you can adjust the vertical and the horizontal alignment of the text, you can rotate the text, etc. You can customize the way the text label appears by using additional arguments. For example, let’s label the point (2014, 62.33). In case you only want to label a specific point (or points), use the () function only for those points. Output: Example 1 – Label a point on the scatter plot First, we will create a simple scatter plot. Let’s now look at some examples of using the above syntax. Now to add labels to each point in the scatter plot, use the () function for each point (x, y) and add its appropriate label. # add text, s to a point at (x, y) coordinate in a plot The following is the syntax – import matplotlib.pyplot as plt This is useful when you have an array of axes as returned by plt.subplots, and it is more convenient than using setxticks because in that case you need to also set the tick labels, and also more convenient that those that iterate over the ticks (for obvious. The () function is used to add text at the location (x, y) in the plot. ax.tickparams(axis'x', labelrotation90) Matplotlib documentation reference here. You can use the () function to label points in a matplotlib scatter plot. How to annotate points on a scatter plot in matplotlib? Tweaking a bit harder on xaxis and zaxis doesn't do anything: ax.xaxis.labelpad = 0.In this tutorial, we will look at how to label points on a scatter plot in Matplotlib with the help of some examples. The following brings the yaxis (realizations) quite close to the tick labels, but not xaxis and zaxis labels: ax.xaxis.labelpad = 1 So I figure reducing those numbers should bring them closer. The following pushes the labels quite far away, as expected: ax.xaxis.labelpad = 20 Without touching the padding I have (note the zaxis label for the left plot is off the fig): I just cannot get my tick labels or axis label where I want it. I feel like I have tried everything, including answers here. I should note I am using 3D subplots, perhaps that is my issue? fig = plt.figure(figsize=(3,2))Īx = fig.add_subplot(1,2,i,projection='3d') I'm using mpl 3.4.3 and I am still having this issue. Please check out the revised documentation here. Because the spacings are determined by relative proportions in mplot3d, having a smaller space to work within forces the labels closer together.Īs for other possible avenues for work-arounds, please see the note here.Ī fair warning, this private dictionary is not intended to be a permanent solution, but rather a necessary evil until the refactor of mplot3d is complete.Īlso, v1.1.0 contains many updates to the api of mplot3d. For the next release, I would like to have 3d axes to take up more than the default axes spacing, since the default was designed to take into account that tick labels and axes labels would be outside the axes, which is not the case for mplot3d. I fixed the miscalculation of axes label angles, and I made some adjustments to the spacing. V1.1.0 contains several fixes to improve the state of things. There were also bugs in how mplot3d calculated the angle to render the labels. The reason why the various tricks that typically work in regular 2d plots don't work for 3d plots is because mplot3d was originally written up with hard-coded defaults. I really need to follow StackOverflow more often.
