CLBarChart<T> class

Bar chart generico basato su fl_chart.

Esempio d'uso:

CLBarChart<SalesData>(
  data: salesList,
  xValueMapper: (item, _) => item.month,
  yValueMapper: (item, _) => item.amount,
  barColor: Colors.teal,
)

Properties

barColor → Color?
Colore delle barre. Default: CLTheme.of(context).primary.
final
barWidth → double
Larghezza di ciascuna barra.
final
borderRadius → BorderRadius?
Border radius delle barre.
final
bottomTitleBuilder → Widget Function(double value, TitleMeta meta)?
Builder custom per le label dell'asse inferiore. Se null, usa il risultato di xValueMapper.
final
data → List<T>
Dati sorgente.
final
hashCode → int

no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
leftAxisInterval → double?

final
leftTitleBuilder → Widget Function(double value, TitleMeta meta)?
Builder custom per le label dell'asse sinistro.
final
maxY → double?
Valore massimo asse Y. Se null, viene calcolato automaticamente.
final
minY → double?
Valore minimo asse Y. Default 0.
final
rotateLabels → bool
Ruota automaticamente le label quando la larghezza è sotto rotateThreshold.
final
rotateThreshold → double
Soglia in pixel sotto la quale le label vengono ruotate.
final
runtimeType → Type

no setterinherited
showGrid → bool
Mostra la griglia di sfondo.
final
tooltipBuilder → BarTooltipItem? Function(T item, int index, BarChartRodData rod)?
Builder custom per il tooltip.
final
xValueMapper → String Function(T item, int index)
Estrae la label dell'asse X da un elemento.
final
yValueMapper → double Function(T item, int index)
Estrae il valore numerico dell'asse Y da un elemento.
