AxisScaling class

AxisScaling class

Represents the scaling options of the axis. To learn more, visit the Working with Charts documentation article.

Constructors

Name	Description
AxisScaling()	The default constructor.

Properties

Name	Description
log_base	Gets or sets the logarithmic base for a logarithmic axis.
maximum	Gets or sets the maximum value of the axis.
minimum	Gets or sets minimum value of the axis.
type	Gets or sets scaling type of the axis.

Examples

Shows how to apply logarithmic scaling to a chart axis.

doc = aw.Document()
builder = aw.DocumentBuilder(doc)

chart_shape = builder.insert_chart(aw.drawing.charts.ChartType.SCATTER, 450, 300)
chart = chart_shape.chart

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

# Insert a series with X/Y coordinates for five points.
chart.series.add("Series 1",
    x_values=[1.0, 2.0, 3.0, 4.0, 5.0],
    y_values=[1.0, 20.0, 400.0, 8000.0, 160000.0])

# The scaling of the X-axis is linear by default,
# displaying evenly incrementing values that cover our X-value range (0, 1, 2, 3...).
# A linear axis is not ideal for our Y-values
# since the points with the smaller Y-values will be harder to read.
# A logarithmic scaling with a base of 20 (1, 20, 400, 8000...)
# will spread the plotted points, allowing us to read their values on the chart more easily.
chart.axis_y.scaling.type = aw.drawing.charts.AxisScaleType.LOGARITHMIC
chart.axis_y.scaling.log_base = 20
