I am using mpandroidchart android library. I am implementing line charts. Here can i set the x and y labels on my own? currently it is adding the values based on the dataset provided to the chart. Can you please give some idea on this?

推荐答案

您必须在轴对象上使用格式化程序.

You have to use a formatter on your axis object.

有两种格式化程序XAxisValueFormatter和YAxisValueFormatter.

There is two kind of formatter XAxisValueFormatter and YAxisValueFormatter.

这是我用来将带有后缀"h"的X标签号更改几个小时的代码:

This the code i used to change the X label number with suffix "h" for hours :

//get reference on chart line view
LineChart chart = (LineChart) pActivity.findViewById(R.id.chart);
//set formater for x Label
chart.getXAxis().setValueFormatter(new XAxisValueFormatter() {

        @Override
        public String getXValue(String original, int index, ViewPortHandler viewPortHandler) {
            //return number + "h" here
            // but you can do everything you want here. The string returned will be displayed on chart x label
            return original + "h";
        }
    });
//axis to the bottom
chart.getXAxis().setPosition(XAxisPosition.BOTTOM);
//populate with data
chart.setData(data);
// refresh
chart.invalidate();
