Gráfico de línea de AchartEngine Xaxis Android

Finalmente conseguí la solución que he intentado este código abajo:

 renderer.setXLabels(0); 

Y el código completo de la clase aquí:

El único código que debe agregar a su código actual son las siguientes dos líneas:

 renderer.setXLabels(RESULT_OK); renderer.clearXTextLabels(); 

Asegúrese de agregar estas instrucciones después de declarar la configuración de procesador, pero ANTES del código en el que estableció las etiquetas de texto de eje X personalizadas.

Dado que tiene varios métodos de renderizado en curso en su programa, debe incluir las dos líneas de código al final de los métodos que implementan un XYMultipleSeriesRenderer. Una vez más, asegúrese de añadir esto en su código antes de implementar sus etiquetas de texto personalizado. 🙂
