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.
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). |
Enumeration that indicates a logical location for an axis.
The location is dependent on the values of the other axis.
- See also:
- WAxis::setLocation(AxisLocation)
- Enumerator:
-
MinimumValue |
At the minimum value. |
MaximumValue |
At the maximum value. |
ZeroValue |
At the zero value (if displayed). |
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. |
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). |
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. |
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.
- See also:
- WDataSeries::setFillRange(FillRange 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 that specifies options for the labels.
- See also:
- WPieChart::setDisplayLabels(int)
- 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 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. |
Enumeration that specifies the type of a chart series.
- See also:
- WDataSeries::setType(SeriesType)
WCartesianChart
- Enumerator:
-
PointSeries |
Series rendered solely as point markers. |
LineSeries |
Series rendered as points connected by straight lines. |
CurveSeries |
Series rendered as points connected by curves. |
BarSeries |
Series rendered as bars. |
