vs
sns.scatterplot(x = ‘col name’, y = ‘col name’, data = df)
Do you need a y value for a count plot?
No
What are the hues in seaborn code names?
Blue = b Green = g Red = r Cyan = c Purple = m Yellow = y Black = k White = w
How do you change the order in a legend?
hue_order = []
What are the benefits of relplot over scatter plot?
You can show subplots
How can you show subplots?
relplot
How do you get a scatter in a relplot?
sns.replot(x = ‘x’, y = ‘y’, data = df, kind = ‘scatter’)
How do you show subplots horiztonally?
sns.replot(x = ‘x’, y = ‘y’, data = df, kind = ‘scatter’, rows = ‘variable’)
How do you show subplots vertically?
sns.replot(x = ‘x’, y = ‘y’, data = df, kind = ‘scatter’, col = ‘variable’)
How do you show subplots both vertically and horiztonally?
sns.replot(x = ‘x’, y = ‘y’, data = df, kind = ‘scatter’, col = ‘variable’, row = ‘variable’)
How do you limit how many subplots are show in columns at one time?
sns.replot(x = ‘x’, y = ‘y’, data = df, kind = ‘scatter’, col = ‘variable’, col_wrap = 2)
How do you specify the order of subplots?
sns.replot(x = ‘x’, y = ‘y’, data = df, kind = ‘scatter’, col = ‘variable’, col_wrap = 2, col_order = [])
Hue only takes colour inputs?
False - you can pass it a categorical variable to colour by type
How do you change the marker for categorical variables?
style = ‘categorical variable’
how do you get a line plot
sns.relplot(x = , y = , data = , kind = ‘line’)
What does a line chart by default show?
confidence interval?
How do you change confidence interval to standard deviation?
sns.relplot(x = , y =, data =, kind = ‘line’, ci = ‘sd’)
What should you use for categorical data?
sns.catplot(x = , y = , data = , kind = ‘count’ or ‘bar’)
How do you set what order categories come in
order = []
How do you turn off confidence intervals
ci = None
How do you elimanate outliers from boxplots?
sym = “”
How do you change lengths of whiskers in a boxplot?
whis = [bottom percentile, top percentile] whis = 2.0 (2 times the IQR)
How do you generate a boxplot?
sns. boxplot()
sns. catplot(kind = ‘box’)
What is the difference between a point plot and a line plot?
Point plot has one categorical variable, line plot has 2 quantitative variables
How do you get a point plot?
kind = ‘point’
How do you remove the line between points on a point plot?
join = False
How do you get a point plot to use median instead of mean/
from numpy import median
estimator = median
How do you add a block to the end of the ci of the pointplot?
capsize = x
How do you change the style of a plot?
sns.set_style()
What are the options under set_style?
“white” “dark” “whitegrid” “darkgrid” “ticks”
How do you change the style of colours?
sns.set_palette()
What are options of set_palette?
“RdBu”
“PRGn”
“RdBu_r”
How do you reverse a colour palette?
Add _r at the end of the code eg
“RdBu_r”
How do you get sequential palettes?
sns.set_palette(“Greys”)
What are the options for sequential colour palettes?
“Greys”
“Blues”
“PuRd”
“GnBu”
How do you create a bespoke colour palette?
Custom = [“red”, “green”, “blue”]
sns.set_palette(Custom)
Or
sns.color_palette(‘Purples’,8)
How do you change the scale of the plot?
sns.set_context() “paper” “notebook” “talk” “poster”
What is a facetgrid?
An object that contains one or more axes subplots
What are the 2 objects that seaborn plots create?
Axes subplot
Facet grid
How do you find out what type of object seaborn has created?
g = sns.scatterplot(x = , y = , data = )
type(g)
What objects do relplot and catplot generate?
facetgrid
What objects do scatter and boxplot generate?
axes subplot
How do you add a title to a facetgrid?
1) give it a variable name
2) g.fig.suptitle()
How do you add a title to an axes subplot?
Assign it to a variable; g
g.set_title()
How do you raise the height of the title
g.fig.suptitle(y = 1.5)
How do you add a title to a facetgrid that is split by columns / rows?
g. fig.suptitle() for over both
g. set_titles() for the subpltots
How do you add axes lables?
g.set(xlabel = , ylabel = )
Works for both facet grid and axes subplot
Is there a difference with how do you set axes labels between facet grid and axes subplots?
No
How do you rotate labels?
plt.xticks(rotation = 90)
How do you get a histogram in seaborn?
sns.distplot(df[‘variable’])
How do you remove the kde in distplot?
sns.distplot(df[‘col’], kde = False, bins = 10)
How do you get just the kde?
sns.distplot(df[‘col’, hist =False)
How do you shade under the kde?
sns.distplot(df[‘col’, hist = False, kde_ksw = {‘shade’: True})
How do you get a regression?
sns. lmplot
sns. regplot
Should you use lm plot or reg plot?
lmplot allows arranging data by columns
How do you remove axes?
sns.despine(left = True)
How do you show a chart with the color palette?
sns.palplot(sns.color_palette(‘Purples’,8))
What are the different chart types you can generate using catplot?
stripplot() kind = 'strip' swarmplot() kind = 'swarm' boxplot() = kind= 'box' violinplot() kind = 'violin' boxenplot() kind = 'boxen' pointplot() kind = 'point' barplot() kind = 'bar' countplot() kind = 'count'
What is the difference between a bar plot and a count plot?
Count actually counts, bar averages
How do you create bins of categorical data?
sns.regplot(x = , y = , data = , x_bins = )
How do you specific which columns to plto in a pairport?
vars or x_vars or y_vars
Can you plot different variables on the axes of a pair plot?
Yes x_vars or y_vars
How do you change what is plotted on the diagonal of the pairport?
sns.pairplot(diag_kind = )
How do you use a training dataset?
sns.load_dataset(‘’)
How do you get a chart with histogram on the side?
sns.jointplot(x = , y = , data = )
What are the different types of plot in seaborn?
Relational
Categorical
Distribution
Regression
What are the types of relational plot?
scatterplot() (with kind=”scatter”; the default)
lineplot() (with kind=”line”)
What are the types of categorical plot?
Categorical scatterplots:
stripplot() (with kind=”strip”; the default)
swarmplot() (with kind=”swarm”)
Categorical distribution plots:
boxplot() (with kind=”box”)
violinplot() (with kind=”violin”)
boxenplot() (with kind=”boxen”)
Categorical estimate plots:
pointplot() (with kind=”point”)
barplot() (with kind=”bar”)
countplot() (with kind=”count”)
What are the types of distribution plot?
The axes-level functions are histplot(), kdeplot(), ecdfplot(), and rugplot().
What are the types of regression plot?
These functions, regplot() and lmplot()
How do you invoke the generic categorical plot?
Catplot
How do you invoke the generic quantitative plot?
relplot
How do you invoke the generic distribution?
displot
How do you invoke the regressino plot?
lmplot has more flexibility than regplot
