Transpose Series Tool doesn't work properly. Basically, the tool changes the initial order series values and also, modifies all the series values for last value. The code below shows the problem:

        public Form1()
        {
            InitializeComponent();
            InitializeChart();
        }

        private Steema.TeeChart.Tools.SeriesTranspose seriesTranspose1;
        private Steema.TeeChart.Styles.Bar bar1; 
       
        private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;
            bar1 = new Steema.TeeChart.Styles.Bar(tChart1.Chart);
            bar1.Marks.Visible = false;
            bar1.FillSampleValues(5);
            //Tool
            seriesTranspose1 = new Steema.TeeChart.Tools.SeriesTranspose(tChart1.Chart);
            button1.Click += Button1_Click;
            button2.Click += Button2_Click;
        }

        private void Button2_Click(object sender, EventArgs e)
        {
            tChart1.ShowEditor();
        }

        private void Button1_Click(object sender, EventArgs e)
        {
            seriesTranspose1.Transpose();
        }
