我已经使用setLabelCount()命令固定了Y轴值.但是如何固定图表中的X轴值.对于上面的代码，我形成了以下图表. http://i.stack.imgur.com/KJMKA.png"rel =" noreferrer>图表1

I Have fixed the Y-Axis values by using setLabelCount() command.But how to fix the number of X-Axis values in my chart..For the above code i have the following chart formed.Chart1 Chart2..These are the two charts formed for different arguments given to the plotchart(String [],float[]) method.In all these charts I am facing the problem that it is not showing the fixed number of x-axis values.Somewhere it is showing 9 values and somewhere it is showing 7 values..And one more issue I am facing is that my first and the last Y-Axis values are getting hidden in my display.

推荐答案

setLabelCount()属性也适用于xAxis.

setLabelCount() property is there for xAxis too.

 XAxis xAxis = lineChart.getXAxis();
 xAxis.setLabelCount(5);
