Constructors

Name	Description
AxisDisplayUnit()	The default constructor.

Properties

Name	Description
custom_unit	Gets or sets a user-defined divisor to scale display units on the value axis.
document	Returns the document containing the parent chart.
unit	Gets or sets the scaling value of the display units as one of the predefined values.

Examples

Shows how to manipulate the tick marks and displayed values of a chart axis.

doc = aw.Document()
builder = aw.DocumentBuilder(doc=doc)
shape = builder.insert_chart(chart_type=aw.drawing.charts.ChartType.SCATTER, width=450, height=250)
chart = shape.chart
self.assertEqual(1, chart.series.count)
self.assertEqual('Y-Values', chart.series[0].name)
# Set the minor tick marks of the Y-axis to point away from the plot area,
# and the major tick marks to cross the axis.
axis = chart.axis_y
axis.major_tick_mark = aw.drawing.charts.AxisTickMark.CROSS
axis.minor_tick_mark = aw.drawing.charts.AxisTickMark.OUTSIDE
# Set they Y-axis to show a major tick every 10 units, and a minor tick every 1 unit.
axis.major_unit = 10
axis.minor_unit = 1
# Set the Y-axis bounds to -10 and 20.
# This Y-axis will now display 4 major tick marks and 27 minor tick marks.
axis.scaling.minimum = aw.drawing.charts.AxisBound(value=-10)
axis.scaling.maximum = aw.drawing.charts.AxisBound(value=20)
# For the X-axis, set the major tick marks at every 10 units,
# every minor tick mark at 2.5 units.
axis = chart.axis_x
axis.major_unit = 10
axis.minor_unit = 2.5
# Configure both types of tick marks to appear inside the graph plot area.
axis.major_tick_mark = aw.drawing.charts.AxisTickMark.INSIDE
axis.minor_tick_mark = aw.drawing.charts.AxisTickMark.INSIDE
# Set the X-axis bounds so that the X-axis spans 5 major tick marks and 12 minor tick marks.
axis.scaling.minimum = aw.drawing.charts.AxisBound(value=-10)
axis.scaling.maximum = aw.drawing.charts.AxisBound(value=30)
axis.tick_labels.alignment = aw.ParagraphAlignment.RIGHT
self.assertEqual(1, axis.tick_labels.spacing)
# Set the tick labels to display their value in millions.
axis.display_unit.unit = aw.drawing.charts.AxisBuiltInUnit.MILLIONS
# We can set a more specific value by which tick labels will display their values.
# This statement is equivalent to the one above.
axis.display_unit.custom_unit = 1000000
