如何为MPAndroidChart左轴上的中间值设置句点?

不确定我是否正确理解了您的问题的意图,但如果您希望轴以100的倍数显示值,您可以尝试这样做:

YAxis leftAxis = mBarChart.getAxisLeft();
leftAxis.setGranularity(100f);
leftAxis.setGranularityEnabled(true);

参见文档了解 setGranularity 和 setGranularityEnabled this answer .

是的,可以使用更改中间范围

mBarChart.getAxisLeft().setGranularity(100f);
mBarChart.getAxisLeft().setGranularityEnabled(true);

        private float yAxisScaleDifference = -1;
        private boolean granularitySet = false;
        //[10,120,250]
        mBarChart.getAxisLeft().setValueFormatter(new IAxisValueFormatter() {
        @Override
        public String getFormattedValue(float v, AxisBase axisBase) {
            if(!granularitySet) {

                if(yAxisScaleDifference == -1) {
                    yAxisScaleDifference = v;  //10
                }
                else {
                    float diff = v - yAxisScaleDifference;  //120 - 10 = 110
                    if(diff >= 1000) {
                        yAxisLeft.setGranularity(1000f);  
                    }
                    else if(diff >= 100) {
                        yAxisLeft.setGranularity(100f);  //set to 100
                    }
                    else if(diff >= 1f) {
                        yAxisLeft.setGranularity(1f);
                    }
                    granularitySet =true;
                }
            }
            return val;
        }
    });

另一个例子:

    say Y-Axis returns [1200,3400,8000,9000....]
      first time: 1200
      second time: 3400 - 1200 = 2200
      set to 1000
