Data decision is one of the best important accoutrement we accept to assay data. But it’s aloof as accessible to mislead as it is to brainwash application archive and graphs. In this commodity we’ll booty a attending at 3 of the best accepted means in which visualizations can be misleading.

One of the easiest means to adulterate your abstracts is by messing with the y-axis of a bar graph, band graph, or besprinkle plot. In best cases, the y-axis ranges from 0 to a best amount that encompasses the ambit of the data. However, sometimes we change the ambit to bigger highlight the differences. Taken to an extreme, this abode can accomplish differences in abstracts assume abundant beyond than they are.

Let’s see how this works in practice. The two graphs beneath appearance the exact aforementioned data, but use altered scales for the y-axis:

On the left, we’ve accountable the y-axis to ambit from 3.140% to 3.154%. Doing so makes it attending like absorption ante are skyrocketing! At a glance, the bar sizes betoken that ante in 2012 are several times college than those in 2008. But announcement the abstracts with a zero-baseline y-axis tells a added authentic picture, area absorption ante are blockage static.

If this archetype seems exaggerated, actuality are some real-world examples of truncated y-axes:

Many bodies opt to actualize accumulative graphs of things like cardinal of users, revenue, downloads, or added important metrics. For example, instead of assuming a blueprint of our annual revenue, we ability accept to affectation a active absolute of acquirement becoming to date. Let’s see how this ability look:

We can’t acquaint abundant from this graph. It’s affective up and to the right, so things charge be activity well! But the non-cumulative blueprint paints a altered picture:

Now things are a lot clearer. Revenues accept been crumbling for the accomplished ten years! If we yze the accumulative graph, it’s accessible to acquaint that the abruptness is abbreviating as time goes on, advertence shrinking revenue. However, it’s not anon obvious, and the blueprint is abundantly misleading.

There are lots of real-world cases of accumulative graphs that accomplish things assume a lot added absolute than they are. A arresting archetype is Apple’s acceptance of a accumulative blueprint to appearance iPhone sales.

One of the best insidious approach bodies use in amalgam ambiguous abstracts visualizations is to breach accepted practices. We’re acclimated to the actuality that pie archive represent genitalia of a accomplished or that timelines advance from larboard to right. So back those rules get violated, we accept a difficult time seeing what’s absolutely activity on. We’re active to alter the data, due to our assurance on these conventions.

Here’s an archetype of a pie blueprint that Fox Chicago aired during the 2012 primaries:

The three slices of the pie don’t add up to 100%. The ysis apparently accustomed for assorted responses, in which case a bar blueprint would be added appropriate. Instead, we get the consequence that anniversary of the three candidates accept about a third of the support, which isn’t the case.

Another archetype is this decision appear by Business Insider, which seems to appearance the adverse of what’s absolutely activity on:

At aboriginal glance, it looks like gun deaths are on the abatement in Florida. But a afterpiece attending shows that the y-axis is upside-down, with aught at the top and the best amount at the bottom. As gun deaths increase, the band slopes downward, actionable a able-bodied accustomed assemblage that y-values access as we move up the page.

There’s a simple takeaway from all this: be accurate back designing visualizations, and be added accurate back interpreting graphs created by others. We’ve covered three accepted techniques, but it’s aloof the apparent of how bodies use abstracts decision to mislead.
