AxisScaleType enumeration

Specifies the possible scale types for an axis.

Members

NameDescription
LINEARLinear scaling.
LOGARITHMICLogarithmic scaling.

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
