This tutorial will go over more advanced plotting functionality. Before reading this, you should take a look at the basic analysis and plotting tutorial. First, we'll load in some example data. This dataset is an egg
comprised of 30 subjects, who each performed 8 study/test blocks of 16 words each.
In [ ]:
import quail
%matplotlib inline
egg = quail.load_example_data()
In [ ]:
accuracy = egg.analyze('accuracy')
accuracy.get_data().head()
By default, the analyze
function will perform an analysis on each list separately, so when you plot the result, it will plot a separate bar for each list, averaged over all subjects:
In [ ]:
ax = accuracy.plot()
We can plot the accuracy for each subject by setting plot_type='subject'
, and we can change the name of the subject grouping variable by setting the subjname
kwarg:
In [ ]:
ax = accuracy.plot(plot_type='subject', subjname='Subject Number')
Furthermore, we can add a title using the title
kwarg, and change the y axis limits using ylim
:
In [ ]:
ax = accuracy.plot(plot_type='subject', subjname='Subject Number',
title='Accuracy by Subject', ylim=[0,1])
In addition to bar plots, accuracy can be plotted as a violin or swarm plot by using the plot_style
kwarg:
In [ ]:
ax = accuracy.plot(plot_type='subject', subjname='Subject Number',
title='Accuracy by Subject', ylim=[0,1], plot_style='violin')
ax = accuracy.plot(plot_type='subject', subjname='Subject Number',
title='Accuracy by Subject', ylim=[0,1], plot_style='swarm')
We can also group the subjects. This is useful in cases where you might want to compare analysis results across multiple experiments. To do this we will reanalyze the data, averaging over lists within a subject, and then use the subjgroup
kwarg to group the subjects into two sets:
In [ ]:
accuracy = egg.analyze('accuracy', listgroup=['average']*8)
accuracy.get_data().head()
In [ ]:
ax = accuracy.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15)
Oops, what happened there? By default, the plot
function looks to the List column of the df to group the data. To group according to subject group, we must tell the plot function to plot by subjgroup
. This can be achieved by setting plot_type='subject'
:
In [ ]:
ax = accuracy.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15, plot_type='subject')
If you also have a list grouping (such as first 4 lists / second 4 lists), you can plot the interaction by setting plot_type='split'
. This will create a plot with respect to both the subjgroup
and listgroup
:
In [ ]:
accuracy = egg.analyze('accuracy', listgroup=['First 4 Lists']*4+['Second 4 Lists']*4)
ax = accuracy.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15, plot_type='split')
Like above, these plots can also be violin or swarm plots:
In [ ]:
ax = accuracy.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15, plot_type='split', plot_style='violin')
ax = accuracy.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15, plot_type='split', plot_style='swarm')
The Memory Fingerprint plotting works exactly the same as the the accuracy plots, with the except that plot_type='split'
only works for the accuracy plots, and the default plot_style
is a violinplot, instead of a barplot.
In [ ]:
fingerprint = egg.analyze('fingerprint', listgroup=['First 4 Lists']*4+['Second 4 Lists']*4)
ax = fingerprint.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15, plot_type='subject')
ax = fingerprint.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15, plot_type='list')
In [ ]:
listgroup = ['First 4 Lists']*4+['Second 4 Lists']*4
plot_type = 'list'
spc = egg.analyze('spc', listgroup=listgroup)
ax = spc.plot(plot_type=plot_type, ylim=[0, 1])
pfr = egg.analyze('pfr', listgroup=listgroup)
ax = pfr.plot(plot_type=plot_type)
lagcrp = egg.analyze('lagcrp', listgroup=listgroup)
ax = lagcrp.plot(plot_type=plot_type)
In [ ]:
listgroup=['average']*8
subjgroup = ['Experiment 1']*15+['Experiment 2']*15
plot_type = 'subject'
spc = egg.analyze('spc', listgroup=listgroup)
ax = spc.plot(subjgroup=subjgroup, plot_type=plot_type, ylim=[0,1])
pfr = egg.analyze('pfr', listgroup=listgroup)
ax = pfr.plot(subjgroup=subjgroup, plot_type=plot_type)
lagcrp = egg.analyze('lagcrp', listgroup=listgroup)
ax = lagcrp.plot(subjgroup=subjgroup, plot_type=plot_type)
