AxisBound class

AxisBound class

Represents minimum or maximum bound of axis values. To learn more, visit the Working with Charts documentation article.

Remarks

Bound can be specified as a numeric, datetime or a special “auto” value.

The instances of this class are immutable.

Constructors

NameDescription
AxisBound()Creates a new instance indicating that axis bound should be determined automatically by a word-processing application.
AxisBound(value)Creates an axis bound represented as a number.
AxisBound(datetime)Creates an axis bound represented as datetime value.

Properties

NameDescription
isAutoReturns a flag indicating that axis bound should be determined automatically.
valueReturns numeric value of axis bound.
valueAsDateReturns value of axis bound represented as datetime.

Examples

Shows how to insert chart with date/time values.

let doc = new aw.Document();
let builder = new aw.DocumentBuilder(doc);

let shape = builder.insertChart(aw.Drawing.Charts.ChartType.Line, 500, 300);
let chart = shape.chart;

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

// Add a custom series containing date/time values for the X-axis, and respective decimal values for the Y-axis.
chart.series.add("Aspose Test Series",
  [
    Date.parse("2017-11-06"), Date.parse("2017-11-09"), Date.parse("2017-11-15"),
    Date.parse("2017-11-21"), Date.parse("2017-11-25"), Date.parse("2017-11-29")
  ],
  [ 1.2, 0.3, 2.1, 2.9, 4.2, 5.3 ]);


// Set lower and upper bounds for the X-axis.
let xAxis = chart.axisX;
xAxis.scaling.minimum = new aw.Drawing.Charts.AxisBound(Date.parse("2017-11-05"));
xAxis.scaling.maximum = new aw.Drawing.Charts.AxisBound(Date.parse("2017-12-03"));

// Set the major units of the X-axis to a week, and the minor units to a day.
xAxis.baseTimeUnit = aw.Drawing.Charts.AxisTimeUnit.Days;
xAxis.majorUnit = 7.0;
xAxis.majorTickMark = aw.Drawing.Charts.AxisTickMark.Cross;
xAxis.minorUnit = 1.0;
xAxis.minorTickMark = aw.Drawing.Charts.AxisTickMark.Outside;
xAxis.hasMajorGridlines = true;
xAxis.hasMinorGridlines = true;

// Define Y-axis properties for decimal values.
let yAxis = chart.axisY;
yAxis.tickLabels.position = aw.Drawing.Charts.AxisTickLabelPosition.High;
yAxis.majorUnit = 100.0;
yAxis.minorUnit = 50.0;
yAxis.displayUnit.unit = aw.Drawing.Charts.AxisBuiltInUnit.Hundreds;
yAxis.scaling.minimum = new aw.Drawing.Charts.AxisBound(100);
yAxis.scaling.maximum = new aw.Drawing.Charts.AxisBound(700);
yAxis.hasMajorGridlines = true;
yAxis.hasMinorGridlines = true;

doc.save(base.artifactsDir + "Charts.DateTimeValues.docx");
