sysplot.add_tick_line#

add_tick_line(value, label, axis=None, offset=0.0, color=None, text_kw=None, **kwargs)[source]#

Draw a dotted reference line and label at a specific axis value.

Adds a labeled tick at value without modifying the existing major tick locator. Useful for highlighting key values such as resonance frequencies or time constants.

Parameters:

value (float) – Tick position in data coordinates.
label (str) – Text to display at the tick.
axis (XAxis | YAxis | None) – Target axis (ax.xaxis or ax.yaxis). Defaults to the current x-axis.
offset (float) – Fractional offset along the perpendicular axis for the label (axis coordinates). Negative values place the label below/left.
color (str | None) – Color of the reference line and label. If None, uses the default text color.
text_kw (dict | None) – Extra keyword arguments forwarded to the text annotation (e.g. fontsize, fontweight, color). If color is provided here, it is also used as the axvline and axhline color.
**kwargs – Additional keyword arguments forwarded to axhline or axvline (e.g. linewidth, linestyle, alpha, zorder).
