MPAndroidChart - Offset oben hinzufügen

Question

Gibt es eine Möglichkeit, Padding \ Offset nach oben hinzuzufügen? Siehe Bildschirm. Die Ziffern werden abgeschnitten, wenn LimitLine oben ist:

Answer 1

Ich hatte das gleiche Problem und nach viel dort dachte suchen ist keine direkte Weg, um diesen zusätzlichen Raum zu bekommen. Hier ist, wie ich es tat:

//dont start at zero 
yaxis.setStartAtZero(false); 
//look at your dataset and set the min and max values of the y-axis at runtime 
//keep the range with some extra space - as you want 
yaxis.setAxisMinValue(4); 
yaxis.setAxisMaxValue(8); 

-Code nicht verwendet werden, wie sie ist: 4 und 8 oben sind Zahlen, die meinen Zweck geeignet - die Werte ändern, wie pro Ihre Datenpunkte
