Values and symbols along a sequence¶
Use these tracks when each genomic position, window or aligned column carries a measurement or symbol. The important choice is whether zero is a floor, a baseline to cross, or not part of the scale at all.

Dense or sparse signalCoverageTrackPer-base depth, GC content or mappability reduced honestly when several bases share a pixel.Open reference
Signed window statisticWindowTrackpN/pS, GC skew or Tajima's D drawn on both sides of the baseline they are interpreted against.Open reference
Per-site fractionMethylationTrackForward and reverse methylation calls kept separate, with depth filtering and hemimethylation queries.Open reference
Reference symbolsSequenceTrackBases become letters, blocks or a zoom hint according to the actual pixel resolution.Open reference

Choose the baseline first¶
| If the value… | Start with | Why |
|---|---|---|
| cannot be negative and zero is the floor | CoverageTrack |
Area, line or bars rise from a meaningful zero. |
| is interpreted relative to zero, one or another reference | WindowTrack |
Both sides of the baseline remain visible. |
| belongs to one strand at a named site | MethylationTrack |
Strand and read support remain part of the datum. |
| is a symbol rather than a number | SequenceTrack or LogoTrack |
The renderer changes representation with resolution or column composition. |
