ChartAxis

class ChartAxis

A primary chart axis, accessed through Chart.category_axis or Chart.value_axis.

Use set() to change several attributes in one operation. On xlwings Lite, use the asynchronous getters to fetch the current values from Excel.

>>> chart = xw.books["Book1"].sheets[0].charts[0]
>>> chart.value_axis.set(
...     title="Revenue", minimum_scale=0, major_unit=10_000
... )

set(*, title=..., minimum_scale=..., maximum_scale=..., major_unit=..., number_format=..., visible=...)

Sets one or more axis attributes in one operation.

Only supplied attributes are changed, and all arguments are validated before anything is written. visible=True is applied before the other attributes; visible=False is applied last so it describes the final state.

参数:

• title (str | None) -- Axis title, or None to hide it.

• minimum_scale (float | None) -- Minimum scale, or None for automatic scaling.

• maximum_scale (float | None) -- Maximum scale, or None for automatic scaling.

• major_unit (float | None) -- Positive major-unit interval, or None for automatic.

• number_format (str) -- Format code for the tick labels.

• visible (bool) -- Whether the axis is shown.

property title: str | None

Returns or sets the axis title. Setting it to None hides the title; setting it to a string shows the axis and its title.

property visible: bool

Returns or sets whether the axis is shown.
