Positive values don't work for minimum chart bounds?

[mercior]

If I take this base code:

        GUIChartEditor.BeginChart(0, 400, 0, 200, Color.black,
            GUIChartEditorOptions.ChartBounds(0, 10, 0, 10),
            GUIChartEditorOptions.SetOrigin(ChartOrigins.BottomLeft),
            GUIChartEditorOptions.ShowAxes(Color.white)
        );

        GUIChartEditor.PushPoint(new Vector2(0, 5), Color.red);
        GUIChartEditor.PushPoint(new Vector2(5, 5), Color.red);
        GUIChartEditor.PushPoint(new Vector2(10, 5), Color.red);

        GUIChartEditor.EndChart();

I get:

Which is the expected result.

If I set a negative minimum X, like:

GUIChartEditorOptions.ChartBounds(-10, 10, 0, 10),

I get:

Also correct, expected result.

However, if I set a positive minimum value, like:

GUIChartEditorOptions.ChartBounds(5, 10, 0, 10),

I get an unexpected result:

I would expect to see a red dot on the left, and right in this case? Also I note the white y axis line is displaying on the right side of the image which is also unexpected?
