Bar graphs
Another form of graph that you often want to plot is the bar graph. Let’s
use the afl.finalists
data set with the afl.finalists
variable that I
introduced in Mode. What I want to do is draw a bar graph that
displays the number of finals that each team has played in over the time
spanned by the afl.finalists
data set. There are lots of teams, but I am
particularly interested in just four: Brisbane, Carlton, Fremantle and
Richmond. So the first step is to set up a filter so just those four teams are
included in the bar graph. This is straightforward in jamovi and you can do it
by using the Filters
function that we used previously. Open up the
Filters
screen and type in the following:[1]
afl.finalists == "Brisbane" or afl.finalists == 'Carlton' or afl.finalists ==
'Fremantle' or afl.finalists == 'Richmond'
When you have done this you will see, in the Data
view, that jamovi has
filtered out all values apart from those we have specified. Next, open up the
Exploration
→ Descriptives
window and click on the Bar plot
check
box (remember to move the afl.finalists
variable across into the
Variables
box so that jamovi knows which variable to use). You should then
get a bar graph, something like that shown in 그림 30.
