About the problem that the y-axis is not displayed.

[YongfaWang]

My x-axis is displayed normally, but the y-axis is not displayed. How can I solve this? Where is the root of the problem??

I am very grateful to you for solving this problem for me
Here is my code ↓:

`
List axisX = new ArrayList<>();
for(int index = 0; index < GPST.size(); index++)
axisX.add(new AxisValue(index).setLabel(GPST.get(index)));

                    List<AxisValue> axisY = new ArrayList<>();
                    for(int index = 0; index < Dist.size(); index++) {
                        axisY.add(new AxisValue(index).setLabel(Dist.get(index)));
                    }

                    // This is Y axis
                    Axis axis1 = new Axis();
                    axis1.setValues(axisX);
                    axis1.setTextColor(Color.BLUE);

                    // This is Y axis
                    Axis axis2 = new Axis();
                    axis2.setValues(axisY);

                    data.setAxisXBottom(axis2);
                    data.setAxisYLeft(axis1);
                    lineChartView.setLineChartData(data);
