Step detection sensitivity of all diversity measures for standard conditions across five allele proportion treatments (<i>p</i> = 0–1, <i>p</i> = 0.1–0.9, <i>p</i> = 0–0.5, <i>p</i> = 0–0.2, <i>p</i> = 0.3–0.5), each with four step treatments (linear– 0, gentle step– 1, moderate step– 5, steep step– 50).

Both true positives (where a step was detected at the correct location, d = 0.5) and false positives (where a step is detected at the wrong location or any location for the linear treatments) are shown. The remaining values (out of 100) for each treatment were simulations where no step was detected (true negatives for the linear treatments, false negatives for the step treatments). Darker blue represent higher numbers of true positives out of 100 simulations, darker red represents higher numbers of false positives out of 100 simulations.
