Public Functions Documentation¶

function color¶

Returns the color of the category with value , or an invalid color when it has none.

QColor QAccelPlot::Internal::CategoryTable::color (
    int value
) const

function dataPointCategory¶

Returns the category in value , thecategory of the QML data point at__index .

std::optional< int > QAccelPlot::Internal::CategoryTable::dataPointCategory (
    const QVariant & value,
    const char * seriesName,
    qsizetype index
) const

A number must be a whole number; a string is a category name. Returns std::nullopt for a missing or null value, and for any other value, which logs a warning naming seriesName.

function empty¶

Returns true when there are no categories.

bool QAccelPlot::Internal::CategoryTable::empty () const

function entries¶

Returns the categories in list order.

const std::vector< Entry > & QAccelPlot::Internal::CategoryTable::entries () const

function legendEntries¶

Returns one legend entry per category: seriesEntry with the category's name and color.

QList< LegendEntry > QAccelPlot::Internal::CategoryTable::legendEntries (
    const LegendEntry & seriesEntry
) const

A category without a name is labeled with its value; one without a color keeps the series color.

function name¶

Returns the name of the category with value , or an empty string when it has none.

QString QAccelPlot::Internal::CategoryTable::name (
    int value
) const

function problems¶

Returns a description of each category the snapshot skipped or could not name.

const QStringList & QAccelPlot::Internal::CategoryTable::problems () const

Public Static Functions Documentation¶

function fromCategories¶

Takes a snapshot of categories , skipping null entries.

static CategoryTable QAccelPlot::Internal::CategoryTable::fromCategories (
    const QList< Category * > & categories
)

Keeps the first of categories that share a value or a name, and describes each later one in problems().
