Enumerations

Detailed Description

A charting library implemented using the Wt Painting system.

The charting library contains two main chart widget classes, WCartesianChart and WPieChart, and a number of utility classes for drawing simple to complex charts.

Typedef Documentation

typedef std::map<WFlags<KeyboardModifier>, InteractiveAction> Wt::Chart::WheelActions

A map of mouse wheel actions for interactive charts, indexed by WFlags<KeyboardModifier>

Enumeration Type Documentation

Enumeration that indicates a chart axis.

See also
WCartesianChart::axis(Axis)
Enumerator
XAxis 

X axis.

YAxis 

First Y axis (== Y1Axis).

Y1Axis 

First Y axis (== YAxis).

Y2Axis 

Second Y Axis.

OrdinateAxis 

Ordinate axis (== Y1Axis for a 2D plot).

XAxis_3D 

X axis on 3D chart.

YAxis_3D 

Y axis on 3D chart.

ZAxis_3D 

Z axis on 3D chart.

Enumeration that indicates a scale for an axis.

The scale determines how values are mapped onto an axis.

See also
WAxis::setScale(AxisScale scale)
Enumerator
CategoryScale 

A category scale is set as the scale for the X axis in a CategoryChart, and is only applicable there. It lists all values, evenly spaced, and consecutively in the order of the model. The categories are converted to numbers using their ordinal (first category = 0, second = 1, ...).

LinearScale 

A linear scale is the default scale for all axes, except for the X scale in a CategoryScale. It maps values in a linear fashion on the axis.

LogScale 

A logarithmic scale is useful for plotting values with of a large range, but only works for positive values.

DateScale 

A date scale is a special linear scale, which is useful for the X axis in a ScatterPlot, when the X series contain dates (of type WDate). The dates are converted to numbers, as Julian Days.

DateTimeScale 

A datetime scale is a special linear scale, which is useful for the X axis in a ScatterPlot, when the X series contain timedates (of type WDateTime). The dates are converted to numbers, as the number of seconds since the Unix Epoch (midnight Coordinated Universal Time (UTC) of January 1, 1970).

Enumeration that indicates a logical location for an axis.

The location is dependent on the values of the other axis.

See also
WAxis::setLocation(AxisValue)
Enumerator
MinimumValue 

At the minimum value.

MaximumValue 

At the maximum value.

ZeroValue 

At the zero value (if displayed).

BothSides 

At both sides (MinimumValue and MaximumValue).

Enumeration type that indicates a chart type for a cartesian chart.

Enumerator
CategoryChart 

The X series are categories.

ScatterPlot 

The X series must be interpreted as numerical data.

Lists the different ways that a chart can be updated.

Enumerator
CameraMatrix 

Camera matrix.

GLContext 

GL context.

GLTextures 

GL textures.

Enumeration that specifies how an area should be filled.

Data series of type LineSeries or CurveSerie may be filled under or above the line or curve. This enumeration specifies the other limit of this fill. Data series of type BarSeries can use this setting to configure the bottom of the chart.

See also
WDataSeries::setFillRange(FillRangeType range)
WCartesianChart
Enumerator
NoFill 

Do not fill under the curve.

MinimumValueFill 

Fill from the curve to the chart bottom (min)

MaximumValueFill 

Fill from the curve to the chart top.

ZeroValueFill 

Fill from the curve to the zero Y value.

Enumeration of mouse wheel actions for interactive charts.

WCartesianChart::WheelActions
WCartesianChart::setWheelActions(WheelActions)
Enumerator
ZoomX 

Zoom x-axis.

ZoomY 

Zoom y-axis.

ZoomXY 

Zoom along both x and y-axes.

ZoomMatching 

Zoom y-axis on vertical scroll, x-axis on horizontal scroll.

PanX 

Pan x-axis.

PanY 

Pan y-axis.

PanMatching 

Pan y-axis on vertical scroll, x-axis on horizontal scroll.

Enumeration that specifies options for the labels.

See also
WPieChart::setDisplayLabels(WFlags<LabelOption>)
Enumerator
NoLabels 

Do not display labels (default).

Inside 

Display labels inside each segment.

Outside 

Display labels outside each segment.

TextLabel 

Display the label text.

TextPercentage 

Display the value (as percentage)

Enumeration type that indicates a legend location.

Enumerator
LegendInside 

Inside the chart area.

LegendOutside 

Outside the chart area (in the padding area)

Enumeration that specifies a type of point marker.

See also
WDataSeries::setMarker(MarkerType marker)
WCartesianChart
Enumerator
NoMarker 

Do not draw point markers.

SquareMarker 

Mark points using a square.

CircleMarker 

Mark points using a circle.

CrossMarker 

Mark points using a cross (+).

XCrossMarker 

Mark points using a cross (x).

TriangleMarker 

Mark points using a triangle.

CustomMarker 

Mark points using a custom marker.

StarMarker 

Mark points using a star.

InvertedTriangleMarker 

Mark points using an inverted (upside-down) triangle.

Mark points using an asterisk (*).

DiamondMarker 

Mark points using a diamond.

Lists the three orthogonal planes in 3D.

Enumerator
XY_Plane 

X/Y Plane.

XZ_Plane 

X/Z Plane.

YZ_Plane 

Y/Z Plane.
