Problem

The displayed weekly-orders bar chart shows \(\text{East}~=~98\) and \(\text{West}~=~102\) on a \(y\text{-}\text{axis}\) starting at \(90\). Evaluate how the scale represents the \(4\text{-}\text{order}\) difference and propose a repair.

Bar chart of weekly orders showing East 98 and West 102 on a y-axis from 90 to 104. — Weekly orders: East 98; West 102.

Big Picture

What this problem is really about

Compare what the graphic's geometry implies with the relationship in the raw values. For bars, a truncated baseline changes visible lengths to distances above that baseline and can make a small numerical difference look proportionally large, even when labels are accurate. Repair the display with a zero baseline or an unmistakably disclosed break, and report the underlying values clearly.

It is misleading because every truncated axis is invalid regardless of context. Ban the bar chart instead of labeling its scale or reporting values.

It is not misleading because the raw values are printed, so the truncated axis cannot exaggerate the 4-order difference. Keep the unmarked 90 baseline and report raw values.

It is misleading because the colors look unattractive, not because the scale distorts the difference. Change the colors but keep the unmarked axis break and report raw values.

It is misleading because the truncated axis exaggerates the small 4-order difference. Use a zero baseline or clearly mark the break and report raw values.
