Properties

NameDescription
LogBase { get; set; }Gets or sets the logarithmic base for a logarithmic axis.
Maximum { get; set; }Gets or sets the maximum value of the axis.
Minimum { get; set; }Gets or sets minimum value of the axis.
Type { get; set; }Gets or sets scaling type of the axis.

Examples

Shows how to apply logarithmic scaling to a chart axis.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

Shape chartShape = builder.InsertChart(ChartType.Scatter, 450, 300);
Chart chart = chartShape.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",
    new[] { 1.0, 2.0, 3.0, 4.0, 5.0 },
    new[] { 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.AxisY.Scaling.Type = AxisScaleType.Logarithmic;
chart.AxisY.Scaling.LogBase = 20;
