AchartEngine Liniendiagramm Xaxis Android

Question

ich arbeite aChartengine auf android und beendete alle Arbeiten ich habe ein Problem in Liniendiagramm Ich erwähne das Xaxis-Label, aber es ist Shows wie 2,4,6,8,10,12 und so weiter mit Overlay mit meinem Xaxis Label und ich möchte 2,4,6,8,10,12 Labels in Xaxis verstecken. wenn u nicht verstehen Abbildung unten gegeben siehe:

hier ist der vollständige Code:

public class ChartExample extends Activity {

schließlich bekam ich Lösung habe ich unter diesen Code versuchen:

renderer.setXLabels(0); 

und volle Klasse Code hier:

Answer 2

Der einzige Code, den Sie mit Ihrem aktuellen Code hinzufügen müssen die folgenden zwei ist Linien:

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

Stellen Sie sicher, diese Aussagen hinzuzufügen, nachdem Sie Ihre Renderer-Einstellungen erklären, aber BEFORE der Code, in dem Sie Ihre benutzerdefinierten X-Achsen-Textbeschriftungen festlegen.

Da in Ihrem Programm mehrere Renderer-Methoden ausgeführt werden, sollten Sie diese beiden Codezeilen am Ende Ihrer Methoden einfügen, die einen XYMultipleSeriesRenderer implementieren. Stellen Sie sicher, dass Sie dies in Ihrem Code hinzufügen, bevor Sie Ihre benutzerdefinierten Textbeschriftungen implementieren. :)
