Code to reproduce:

            var mChart = new TChart();
            mChart.Aspect.View3D = false;

            mChart.Header.Visible = false;
            mChart.Legend.Visible = false;

            mChart.Axes.Left.AutomaticMinimum = false;
            mChart.Axes.Left.Minimum = 0;
            mChart.Axes.Left.AutomaticMaximum = false;
            mChart.Axes.Left.Maximum = 100;

            mChart.Axes.Bottom.AutomaticMinimum = false;
            mChart.Axes.Bottom.Minimum = 0;
            mChart.Axes.Bottom.AutomaticMaximum = false;
            mChart.Axes.Bottom.Minimum = 100;

            //Line:

            Line line = new Line(mChart.Chart);
            line.LinePen.Width = 2;
            line.Color = System.Drawing.Color.Green;

            line.Smoothed = true;

            line.Add(0, 60);
            line.Add(20, 40);
            line.Add(40, 60);
            line.Add(80, 40);
            line.Add(100, 60);

            mChart.Series.Add(line);

            int i = 1;

            //Holes in the line for some picture sizes:

            mChart.Export.Image.PNG.Width = 240;
            mChart.Export.Image.PNG.Height = 120;
            mChart.Export.Image.PNG.Save($"C:\\TeeChartTest\\chart_{i++:d2}.png");

            mChart.Export.Image.PNG.Width = 320;
            mChart.Export.Image.PNG.Height = 160;
            mChart.Export.Image.PNG.Save($"C:\\TeeChartTest\\chart_{i++:d2}.png");

            mChart.Export.Image.PNG.Width = 520;
            mChart.Export.Image.PNG.Height = 260;
            mChart.Export.Image.PNG.Save($"C:\\TeeChartTest\\chart_{i++:d2}.png");

            mChart.Export.Image.PNG.Width = 800;
            mChart.Export.Image.PNG.Height = 400;
            mChart.Export.Image.PNG.Save($"C:\\TeeChartTest\\chart_{i++:d2}.png");
