One line chart with its argument in the title, built from one club's shot locations, replaces a heat map in the MT241 visualization exercise for Unit 7. Searches like "mt 241 unit 7 assignment example", "mt241 unit 7 sample" and "mt241 unit 7 example" land here.
What a finished MT241 Unit 7 visualization exercise looks like
Three pages: the discarded draft, the final chart and a page of design notes. The draft is a rink diagram with 2,934 unblocked 5-on-5 attempts colored by density, accurate and unreadable at a glance. The final chart has one dark line, the club's monthly share of attempts from the inner slot, the area in front of the net between the faceoff dots, running 34, 33, 29, 27, 26, 27 and 26 percent from October to April. A shaded band marks the league's middle half each month, roughly 31 to 34 percent. A thin vertical rule at November 18 carries a short label: point-shot system introduced. The title states the finding: since mid-November, fewer of the club's shots come from the slot. A caption gives the source, the area's definition and the caveat on recorded locations.
How a MT241 Unit 7 example is structured
Choosing the claim comes before choosing the chart, and the notes record that order: the coaching staff's question was whether the new system traded chance quality for volume, so the chart had to show quality over time against a reference. A monthly share answers that in one line, where the heat map made a viewer compare two dense images. Every design choice is then justified by what it adds to the claim. The league band gives the line a floor and ceiling that a single average would not, and the vertical rule dates the change so cause is suggested without being asserted. Color is spent once, on the club's line, and everything else is gray. The y-axis runs from 20 to 40 percent and says so, because a zero baseline would flatten an eight-point drop. The chart's limits get the last paragraph to themselves.
A heat map, retired
The draft showed where all 2,934 attempts came from, and test viewers could not say what had changed. The notes keep it on the page as the before, with one sentence on why density maps rarely carry an argument over time.
Seven months, a single share
Attempts from the inner slot divided by all unblocked 5-on-5 attempts, month by month. The single line falls from 34 percent in October to 26 by February and stays there, which is the whole finding.
A band for what normal looks like
The league's middle half each month, about 31 to 34 percent, is shaded behind the line. The club starts inside it and leaves it after November, which a lone league average could not show as clearly.
A dated rule, not a causal arrow
A thin vertical rule marks the November 18 switch to a point-shot system. The chart places the drop after the switch; the notes say that timing fits a causal story without proving it.
Recording error, admitted in the caption
Shot locations come from arena scorers and can shift by several feet between buildings. The caption states that a two-point monthly wobble could be recording noise, while an eight-point fall is well beyond it.
Where marks go in MT241 Unit 7
Charts that display a dataset rather than a claim earn little in the MT241 Unit 7 exercise; a heat map or a dashboard of six panels leaves the argument to the reader. Titles that name the variable, slot shot share by month, instead of stating the finding waste the most-read line on the page. Color used for decoration, a different hue per month, competes with the one line that matters. Truncated axes cost marks when unexplained and are accepted when the choice is stated and defended. Missing reference points, no league band or prior season, leave a viewer unable to judge whether a change is large. Drawing a causal arrow where only a timing coincidence is shown overreaches. Design notes, where the prompt asks for them, should justify choices, not describe the chart again.

MT241 Unit 7 questions, answered
How does a sport analytics chart carry a claim?
By being built around one finding a viewer should take away, with every element chosen to make that finding visible. A title that states the claim, a reference such as a league band or a prior season, one highlighted series and muted everything else do most of the work. If a viewer cannot say what the chart shows within a few seconds, it is still a display.
Is it acceptable to start a y-axis above zero?
For line charts showing change in a rate, usually yes, provided the axis is labeled clearly and the choice is explained. Bar charts differ, because bar length encodes the value and a truncated axis exaggerates differences. The example starts at 20 percent and says why in its notes, since a zero baseline would flatten the eight-point drop it exists to show.
What is the inner slot, or home-plate area?
The area directly in front of the net, commonly drawn from the goal posts out to the faceoff dots and up toward the tops of the circles, shaped roughly like a baseball home plate. Shots from there score at far higher rates than shots from the points or the boards, which is why analysts track the share of a team's attempts taken from it.
