Grafico AchartEngine Linea asse X Android

Question

sto achartengine lavorando su Android e completato tutte le opere che ho volto un problema nel grafico a linee potuto menzionare l'etichetta asse X ma è spettacoli come 2.4.6.8.10.12 e così via con sovrapposto con la mia etichetta xaxis e voglio nascondere le etichette 2,4,6,8,10,12 in xaxis. se u non capisco guarda il dato al di sotto figura:

Ecco il codice completo:

Answer 2

l'unico codice che è necessario aggiungere al codice corrente è il seguente due righe:

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

Assicurarsi di aggiungere queste istruzioni dopo aver dichiarato le impostazioni di rendering, ma PRIMA del codice in cui si impostano i asse X etichette di testo personalizzate.

Dato che nel programma sono in esecuzione più metodi di rendering, è necessario includere queste due righe di codice alla fine dei metodi che implementano un XYMultipleSeriesRenderer. Anche in questo caso, assicurati di aggiungere questo nel codice prima di implementare le etichette di testo personalizzate. :)
