MPChart BarChart X轴标签问题

Question

I have implemented MPChart library's BarChart.

When the number of bars in the bar chart are below 9, the labels are aligned to the bars but once the count increases above 9, the labels get skipped and instead of 9 labels on the x - axis it shows only 4-5. Truncating the label string size doesn't help.

My code:

            float index = 0;
            ArrayList<String> xAxisLabel = new ArrayList<>();

            for (Map.Entry<String, Integer> callMapVal : callMap.entrySet()) {
                if (index < 8) {
                    barChartEntries.add(new BarEntry(index, callMapVal.getValue()));
                    if (callMapVal.getKey().length() > 10) {
                        xAxisLabel.add(getTruncated(callMapVal.getKey(), 9));
                    } else {
                        xAxisLabel.add(callMapVal.getKey());
                    }

                }
                index++;
            }

            BarDataSet dataSet = new BarDataSet(barChartEntries, selectedCallType.toString() + " CALLS");
            dataSet.setValueTextSize(8f);
            BarData chartData = new BarData(dataSet);
            dataSet.setColors(ColorTemplate.COLORFUL_COLORS);
            barChart.setData(chartData);
            barChart.getXAxis().setValueFormatter(new IndexAxisValueFormatter(xAxisLabel));
            //barChart.getXAxis().setLabelRotationAngle(20f);
            barChart.getXAxis().setPosition(XAxis.XAxisPosition.BOTTOM);
            barChart.getXAxis().setTextSize(8f);
            //barChart.getXAxis().setAvoidFirstLastClipping(true);
            barChart.getXAxis().setGranularityEnabled(true);
            barChart.getXAxis().setCenterAxisLabels(false);
            barChart.getDescription().setEnabled(false);
            barChart.setFitBars(true); // make the x-axis fit exactly all bars
            barChart.invalidate(); // refresh
            barChart.setScaleEnabled(false);
            barChart.setDoubleTapToZoomEnabled(false);
            barChart.setBackgroundColor(Color.rgb(255, 255, 255));           
            barChart.setDrawBorders(false);
            barChart.setDrawValueAboveBar(true);

您可以将标签数量设置为图表中的条形数量：

barChart.getXAxis().setLabelCount(9, true);
