There are many questions on changing line appearances for line charts, but none quite fit what I want to do. I find it hard to believe I'm the only person that has wanted to do this, but I can't find the answer so...

In the following code I would like to change the line style for 9th row "hissy limit":

mydata.Rows.Add(new Object[] { "RC 50", 70, 65, 60, 55, 50, 45, 40 });
mydata.Rows.Add(new Object[] { "RC 45", 65, 60, 55, 50, 45, 40, 35 });
mydata.Rows.Add(new Object[] { "RC 40", 60, 55, 50, 45, 40, 35, 30 });
mydata.Rows.Add(new Object[] { "RC 35", 55, 50, 45, 40, 35, 30, 25 });
mydata.Rows.Add(new Object[] { "RC 30", 50, 45, 40, 35, 30, 25, 20 });
mydata.Rows.Add(new Object[] { "RC 25", 45, 40, 35, 30, 25, 20, 15 });
mydata.Rows.Add(new Object[] { "User Input", userInput[0], userInput[1], userInput[2], userInput[3], userInput[4], userInput[5], userInput[6] });
mydata.Rows.Add(new Object[] { "Rumble Limit", speechInterferenceLine + 25, speechInterferenceLine + 20, speechInterferenceLine + 15, speechInterferenceLine + 10, null, null, null });
mydata.Rows.Add(new Object[] { "Hissy Limit", null, null, null, null, speechInterferenceLine + 3, speechInterferenceLine + -2, speechInterferenceLine - 7 });
mydata.Rows.Add(new Object[] { "Reference Line", speechInterferenceLine + 20, speechInterferenceLine + 15, speechInterferenceLine + 10, speechInterferenceLine + 5, speechInterferenceLine, speechInterferenceLine - 5, speechInterferenceLine - 10 });

TO THIS:

// Overrideing to dashes
LineAppearance lineApp3 = new LineAppearance();
lineApp3.LineStyle.DrawStyle = LineDrawStyle.Dash;
lineApp3.LineStyle.MidPointAnchors = true;
lineApp3.Thickness = 7;
this.ultraChart1.LineChart.LineAppearances.Add(lineApp3);
