![]() Let me know if that helps or if there's anything that isn't clear. You can just add the "x =" and "y =" to get the axes properly, or you can rearrange the first two parameters so they're in the right order of x, then y Option 1: Changing the labels-just having the x label correspond to price and y label correspond to area So for the seaborn plot, you can either change the labels or change the arguments. This can be seen with the data colors & axis seeming to look "flipped" from the first example: However, since the labels were copy-pasted from the first example, the axis labels corresponded to the wrong axis. In the first example, doing the scatter plot with matplotlib, the x-axis is Area, and the y-axis is Price, with the labels corresponding to the same.įor the second example, doing the scatter plot with seaborn, the x-axis is Price, and the y-axis is Area. I will rather keep using the original, in a later post I will show you how you can mix up R and python code in a single jupyter notebook and how to pass variables between the two environments.I believe the video just has the labels/arguments mismatched in the seaborn example. However there does not seem anything in the python world that beats pure ggplot2. There is a python version of the ggplot which I hear is quite popular and a newr package called altair which is also meant to work on long format. However if you want to plot something a bit more complicated then their showcase examples you get stuck tweaking the plots in matplotlib. However seaborn provides some nice defaults and supports the long data format. Personally I find pure matplotlib very cumbersome. sns.violinplot('variable', 'value', data = df_melt Having multiple plot as output from one code chunk in markdown is a bit tricky, in jupyter notebooks it is not. Handles, labels = ax.get_legend_handles_labels() # get legend handles and labels before drawing legend # the boxes are drawn onto the axis as artist objects ![]() ![]() We can also fix the overlay plot from before # instantiate axis and figureĪx = sns.violinplot('variable', 'value', data = df_meltĪx = sns.boxplot('variable', 'value', data = df_melt sns.lmplot(x = 'petal_length', y = 'petal_width', data = df , zorder = -1 # send boxplot to backgroundįactor Plots (facetting) ax = sns.factorplot('variable', 'value', data = df_meltĪll seaborn plots can be tweaked and edited using matplolib, for example we can add a title and limit the range of the x-axis. Sns.boxplot('variable', 'value', data = df_melt Probably in order to fix this we would need to iterate over the box outlines and set their color attribute to ‘black’ which is a bit of a pain in the ass. The problem is that nevertheless the plot order is a bot messed up and there is no option to change the color of the box outline to black. Sns.boxplot('variable', 'value', data = df_melt, hue = 'species') Here we cannot use hue to assign groups to colors sns.boxplot(data=df)įrom short format df_melt = df.melt(value_vars= plot.scatter( 'petal_length', 'petal_width'Īx = df.query('species = "virginica"') \ # old schoolĪx = df.loc = 'setosa', : ].plot.scatter('petal_length', 'petal_width', label = 'setosa', color = 'blue')Īx = df.query('species = "versicolor"') \ Is a lot more complicated, we have to add each species manually to an axes supplot object. sns.lmplot(x = 'petal_length', y = 'petal_width', data = dfĬompare to matplotlib method plt.scatter() This is in fact a scatter plot function, we just have to turn of the regression fit. seaborn supports long and wide format as input. Seaborn is built on top of matplotlib it provides some pretty decent defaults for matplotlib and has a stunning example gallery. In this post, we’ll provide a comprehensive guide on seaborn’s scatterplot() function. In matplotlib we we woul iterate over every column that we would want to add to our plot while in ggplot we would define x and y measurements and then select a grouping or facetting variable. Scatter plots are one of the most fundamental graphs in your toolkit. The main difference of matplotlib to ggplot2 is that it is optimised for wide formatted data tables while ggplot2 is optimised for data in the long format. It seems that in python you have matplotlib which is fully integrated into pandas and you have seaborn which provides some pretty default setting for most of matplotlib’s standard graph types. In R I am used to work with a combination of ggplot2 and plotly. Compare to matplotlib method plt.scatter().
