Summary: Changing x-y Plot Orientation

Initial Comment:
Is there a way to display a plot with the x-axis in 
the vertical direction, with increasing x values 
going from top to bottom, and the y-axis in the 
horizontal direction, with increasing y values going 
from left to right?  Please let me know if NPlot 
currently has this feature.

Thanks,
Tom

When an x-axis span of 0 is found a minimum span value will
be assigned in order to display the data properly

This is infact a bug.
If the lineplot xaxis data is held constant then the plot
does not display a vertical line of data (as expected).  It
appears that the axis is not being scaled properly.

The functionality of plot is OK because if you set the World
axis values manually the plot appears as expected

not a bug, request for help.

sample to do requested:
private void PlotTest()
    {
            plotSurface.Clear();

            List<int> xData = new List<int>(10);
            List<int> yData = new List<int>(10);

            // Fill the data
            for (int i = 0; i < 10; i++)
            {
                xData.Add(i);
                yData.Add(i + 100);
            }

            // Create a new line plot from array data via
the ArrayAdapter class.
            LinePlot lp = new LinePlot();
            
            // Here is the data plotted the way you
requested it.
            lp.OrdinateData = xData;
            lp.AbscissaData = yData;
            lp.Color = Color.Green;
              

            Grid myGrid = new Grid();
            myGrid.VerticalGridType = Grid.GridType.Fine;
            myGrid.HorizontalGridType = Grid.GridType.Coarse;
            this.plotSurface.Add(myGrid);

            // And add it to the plot surface
            this.plotSurface.Add(lp);

            // This will put the vertical axis in the
direction that you requested
            this.plotSurface.YAxis1.Reversed = true;

            plotSurface.Refresh();
        }
