Enumerations

All enumerations are scoped within AZPlottingClass and use C++11 enum class for type safety.

ScaleType

enum class ScaleType { Linear, Logarithmic, SymLog };

Defines the mathematical transformation applied to axis values.

Value	Description
Linear	Standard linear scale. No transformation applied.
Logarithmic	Base-10 logarithmic scale. Only positive values are displayed; negative and zero values are clamped to a small positive threshold.
SymLog	Symmetric logarithmic scale. Handles negative values by applying sign(x) * log10(1 + |x|/threshold). The region around zero uses linear scaling controlled by linearThreshold and linearWidth.

LineStyle

enum class LineStyle { Solid, Dashed, Dotted, DashDot, None };

Defines the stroke pattern for line series.

Value	Pattern
Solid	Continuous line
Dashed	Long dashes
Dotted	Dots
DashDot	Alternating dash-dot
None	No line (markers only if combined with scatter)

MarkerStyle

enum class MarkerStyle { None, Circle, Square, Diamond, Triangle, Cross, Plus, Star };

Defines the shape of data point markers.

Value	Shape
None	No markers (line only)
Circle	Filled circle
Square	Filled square
Diamond	Filled diamond
Triangle	Filled triangle
Cross	X mark
Plus	Plus sign +
Star	Star shape

TimeUnit

enum class TimeUnit { Seconds, Milliseconds, Microseconds, Auto };

Used with setXAxisTimeFormat() to format the X-axis as a time scale.

Value	Tick Format
Seconds	Values displayed as seconds (s)
Milliseconds	Values displayed as milliseconds (ms)
Microseconds	Values displayed as microseconds (μs)
Auto	Automatically selects unit based on range

Axis

enum class Axis { X, Y, Y2, All };

Used with setAxisTickStyle() to target specific axes.

Value	Description
X	Bottom X-axis
Y	Left Y-axis (primary)
Y2	Right Y-axis (secondary)
All	Apply to all axes

Usage Example

// Using scoped enums
plot->setXAxisScale(AZPlottingClass::ScaleType::Logarithmic);
plot->setYAxisScale(AZPlottingClass::ScaleType::SymLog);

// Line with markers
plot->addLineMarkerSeries(x, y, "Data",
    Qt::blue,
    AZPlottingClass::LineStyle::Solid,
    AZPlottingClass::MarkerStyle::Circle,
    1.5,  // lineWidth
    6.0   // markerSize
);

// Model line (dashed, no markers)
plot->addDataSeries(x, model, "Model",
    Qt::red,
    AZPlottingClass::LineStyle::Dashed,
    1.0
);
