c# - devexpress xtracharts mostrando solo la fecha

datetime

Question

He creado un gráfico de devexpress (v13.2) que tiene datetime en el eje xy valores en el eje Y.

Actualmente en el eje x muestra una fecha como esta:

pero necesito mostrar la fecha y la hora también de manera predeterminada así:

A pesar de que el eje x está codificado para obtener datetime de la base de datos pero aún muestra la fecha, no el tiempo. ¿Por qué?

Answer 1

Pruebe la propiedad Axis.DateTimeOptions y establezca un valor DateTimeFormat apropiado:

((XYDiagram)chartControl1.Diagram).AxisX.DateTimeOptions.Format = DateTimeFormat.General;

Answer 2

El proceso de dos pasos muestra la fecha y la hora en la escala:

1. Establezca la propiedad Axis.DateTimeOptions.Format en DateTimeFormat.General .

2. A continuación, la propiedad Axis.DateTimeScaleOptions con configuraciones personalizadas.

   (XYDiagram)chartControl1.Diagram).AxisX.DateTimeOptions.Format = DateTimeFormat.General;
   (XYDiagram)chartControl1.Diagram).AxisX.DateTimeScaleOptions.GridAlignment = 
                                   DevExpress.XtraCharts.DateTimeGridAlignment.Minute;
   (XYDiagram)chartControl1.Diagram).AxisX.DateTimeScaleOptions.MeasureUnit = 
                                     DevExpress.XtraCharts.DateTimeMeasureUnit.Minute;

Verifique el código y la configuración a continuación para la tabla que me permiten obtener los resultados deseados como desea lograr:

public Form1()
{
    InitializeComponent();
    // This line of code is generated by Data Source Configuration Wizard
    chartDataTableAdapter1.Fill(dbDataSet1.ChartData);
}
