This is not a bug. The reason is that neither Remove nor RemoveAt are designed to Dispose of the series. You can see this in the comment of the SeriesCollection.RemoveAllSeries, which says, "Removes all Series from the Chart but not disposes (destroys) them".
You will note that calling Dispose on the series works as expected:
Steema.TeeChart.Styles.NumericGauge num;
private void InitializeChart()
{
num = new Steema.TeeChart.Styles.NumericGauge();
tChart1.Series.Add(num);
num.FillSampleValues();
}
private void button1_Click(object sender, EventArgs e)
{
num.Dispose();
}

When you use the methods RemoveAt or Series.Remove to clear Numeric Gauges, the Gauge is removed but its markers not. The method works in correct way for the other series. See next code to reproduce the problem: public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { Steema.TeeChart.Styles.NumericGauge num = new Steema.TeeChart.Styles.NumericGauge(); tChart1.Series.Add(num); } private void button2_Click(object sender, EventArgs e) { tChart1.Series.RemoveAt(0); //tChart.Series.Remove(); tChart1.Refresh(); }
