trackc.pl.multi_scale_track(ax: Axes | None = None, regions: Sequence[str] | str | None = None, colors: Sequence[str] | None = None, alpha: float | None = 1, intervals: int | None = 1, scale_adjust: str | None = 'kb', tick_fl: str | None = '%0.2f', tick_fontsize: int | None = 8, tick_rotation: int | None = 0)[source]#

Plot region scale bar, support for multiple or reverse genome regions.

Parameters:

  • ax (matplotlib.axes.Axes object) –

  • regions (str list | str) – e.g. "chr6:1000000-2000000" or ["chr6:1000000-2000000", "chr3:5000000-4000000"] The start can be larger than the end (eg. "chr6:2000000-1000000"), which means you want to get the reverse region

  • colors (str list) – scale bar colors

  • alpha (float) – scale bar alpha

  • intervals (int) – rows of the scale bar by region

  • scale_adjust (str) – options in [‘kb’, ‘Mb’]

  • tick_fl (str) – ticks retains a few decimal places

  • tick_fontsize (int) – ticks text fontsize

  • tick_rotation (int) – ticks text rotation

Example

>>> import trackc as tc
>>> regions = ['7:153000000-151000000', '11:118500000-116500000']
>>> ten = tc.tenon(figsize=(8,1))
>>> ten.add(pos='bottom', height=1)
>>> tc.pl.multi_scale_track(ten.axs(0), regions=regions, scale_adjust='Mb', intervals=2)
