如何使用Android中的MPAndroid图表库将x和y轴叠加在折线图顶部？

Question

I have read the whole documentation of MPAndroid Chart library but haven't found anything to do so. I actually want my chart to extend to full width of screen so that the x and y axis comes to top of the chart. I have attached an image to show how should it look exactly.

Edited: This is my layout xml code.

Answer 1

You can setPosition(YAxisLabelPosition pos): Sets the position where the axis-labels should be drawn. Either INSIDE_CHART or OUTSIDE_CHART.

Also you can set Bottom or Top position.

 XAxis xAxis = chart.getXAxis();
 xAxis.setPosition(XAxisPosition.TOP);
