minor_unit property

ChartAxis.minor_unit property

Returns or sets the distance between minor tick marks.

@property
def minor_unit(self) -> float:
    ...

@minor_unit.setter
def minor_unit(self, value: float):
    ...

Remarks

Valid range of a value is greater than zero. The property has effect for time category and value axes.

Setting this property sets the ChartAxis.minor_unit_is_auto property to False.

Examples

Shows how to insert a chart and modify the appearance of its axes.

# Clear the chart's demo data series to start with a clean chart.
chart.series.clear()

# Insert a chart series with categories for the X-axis and respective numeric values for the Y-axis.
chart.series.add("Aspose Test Series",
    ["Word", "PDF", "Excel", "GoogleDocs", "Note"],
    [640, 320, 280, 120, 150])
