Dear Suppoter,

I am in the process of upgrade Teechart from 4.1.2015 to 4.2002 version. But I got a problem to show the labels of x-axis for bar chart. I am using AxisLabelStyle.PointValue for axis label. It only shows one label on the x axis. All other labels are missing, it used to work fine on the old version of TeeChart. I paste my code as below. Please let me know how to solve it. Thank you.

public partial class Form1 : Form
{
private Steema.TeeChart.TChart chart;
public Form1()
{
InitializeComponent();

chart = new Steema.TeeChart.TChart();
