AxisScaleType enumeration

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(chart_type=aw.drawing.charts.ChartType.SCATTER, width=450, height=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_name='Series 1', x_values=[1, 2, 3, 4, 5], y_values=[1, 20, 400, 8000, 160000])
# 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
