Hi Banzatto

Hi Banzatto

You should change the code of your GetAxisLabel event for below code:

Code: Select all

private void tChart1_GetAxisLabel(object sender, Steema.TeeChart.GetAxisLabelEventArgs e)
        {
            if (sender == tChart1.Axes.Bottom && e.ValueIndex>=0)
            {
                e.LabelText = barra.Labels[e.ValueIndex];
            }    
        }

Another question is that I found that if the first item have an empty string, then the GetAxisLabel event isn't called. So you should to consider it. I've added it (TF02012358) to our defect list to be fixed for future releases.

A workaround can be put a space to first label, if it is empty
