Two errors in Chart FX 7

[FSzymanski]

 I have stumbled across two errors in the .NET control.  I am using version 7.0.4259.29043

• If you only have values of 0 and the Y Axis is set to "Auto" for min and max, the Y Axis will not display any labels at all.  Similarly, if you only have a single X Axis value and the min and max are set to Auto, the X Axis will not have any labels.
• When I set a DataTable as the DataSource and remove the Axis context menu, right clicking an axis item gives me an exception.  I used the following code to reproduce the issue:

  chart1.Data.Clear();
  DataTable table = new DataTable();
  table.Columns.Add("enc_timestamp", typeof(DateTime));
  table.Columns.Add("value", typeof(double));
  DataRow row = table.NewRow();
  row["enc_timestamp"] = DateTime.Now.AddDays(-60);
  row["value"] = 5.0;
  table.Rows.Add(row);
  row = table.NewRow();
  row["enc_timestamp"] = DateTime.Now.AddDays(-30);
  row["value"] = 25.0;
  table.Rows.Add(row);
  row = table.NewRow();
  row["enc_timestamp"] = DateTime.Now;
  row["value"] = 75.0;
  table.Rows.Add(row);
  chart1.DataSourceSettings.DataSource = table;
  chart1.Commands[(int)CommandId.ContextMenuAxis].SubCommands.Clear();
