I'm trying to fill up a plotsurface with the data found within.

What end up happening is that this AddIndicator method - does do it's job -
but the data lines are squished down tiny. I know they're there as I can use
a Y axis interaction to increase their height. But how to instantly fill the
plotsurface with the data?

indicatorPlot.YAxis1.AutoScaleTicks = true;

does not autoscale the lines.

clues?




        protected NPlot.Windows.PlotSurface2D AddIndicator(DataTable dt,
string name, string controlKey, string absiscca, string[] lineNames)
        {
            Control[] ctrls = this.Controls.Find("ExtraIndicators", true);

            NPlot.Windows.PlotSurface2D indicatorPlot = null;
            bool foundIt = false;

            if (ctrls.Length > 0)
            {
                foreach (Control ctrl in ctrls)
                {
                    if ((string)ctrl.Tag == controlKey)
                    {
                        indicatorPlot = (NPlot.Windows.PlotSurface2D)ctrl;
                        indicatorPlot.Clear();
                        foundIt = true;
                        break;
                    }
                }
            }

            if (!foundIt)
            {
                indicatorPlot = new NPlot.Windows.PlotSurface2D();
                indicatorPlot.Name = "ExtraIndicators";
                indicatorPlot.Tag = controlKey;
            }

            indicatorPlot.AddInteraction(new
NPlot.Windows.PlotSurface2D.Interactions.HorizontalDrag());
            indicatorPlot.AddInteraction(new
NPlot.Windows.PlotSurface2D.Interactions.AxisDrag(true));
            indicatorPlot.InteractionOccured += new
NPlot.Windows.PlotSurface2D.InteractionHandler(extraIndicator_InteractionOccured);
            pricePS.InteractionOccured += new
NPlot.Windows.PlotSurface2D.InteractionHandler(extraIndicator_InteractionOccured);

            //indicatorPlot.Anchor =
((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top
| System.Windows.Forms.AnchorStyles.Bottom)
            //| System.Windows.Forms.AnchorStyles.Left)
            //| System.Windows.Forms.AnchorStyles.Right)));

            indicatorPlot.Dock = DockStyle.Fill;
            indicatorPlot.BackColor = Color.Cornsilk;
            indicatorPlot.PlotBackColor = Color.Ivory;

            indicatorPlot.DateTimeToolTip = false;
            indicatorPlot.Width = pricePS.Width;
            indicatorPlot.Left = pricePS.Left;
            this.splitContainer2.Panel2.Controls.Add(indicatorPlot);

            foreach (string lineName in lineNames)
                DrawIndicatorLine(dt, indicatorPlot, name, absiscca,
lineName, Color.BlueViolet);

            indicatorPlot.SmoothingMode =
System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
            indicatorPlot.Add(new Grid());
            indicatorPlot.YAxis1.Label = name;
            indicatorPlot.YAxis1.LabelOffsetAbsolute = true;
            indicatorPlot.YAxis1.LabelOffset = 45;
            indicatorPlot.YAxis1.AutoScaleTicks = true;
            indicatorPlot.Padding = new System.Windows.Forms.Padding(5); ;

            indicatorPlot.Invalidate();
            return indicatorPlot;

        }
