I want to create a single graph linked to the right axis.

If I create the chart in on_load event, everything looks ok:

but if I create the chart later, the left axis remains visible.

This is a weird difference in behavior, what can I do to hide it? Setting Axis.IsVisible = false is not an option, because it hides even vertical line:

            double[] values = Generate.RandomNormal(50, stdDev: 0.2);
            var sig = formsPlot1.Plot.Add.Signal(values);
            sig.Axes.YAxis = formsPlot1.Plot.Axes.Right;
            // formsPlot1.Plot.Axes.Left.IsVisible = false;

            formsPlot1.Plot.Axes.AutoScale();
            formsPlot1.Refresh();
