C-Slope of an Average + 'AverageType' Usage in a Label

[Chuck]

#hint:Plots the tangent angle of the inputted average
declare lower;
input length = 9;#hint length:The number agg-bars of the average
input price = close;#hint Price:The price choice being evaluated
input averageType = AverageType.EXPONENTIAL;#hint averageType:Select the average type desired

def avg = MovingAverage(averageType, price, length);
def height = avg - avg[length];

plot "Angle, deg" = ATan(height / length) * 180 / Double.Pi;
"Angle, deg".AssignValueColor(if "Angle, deg" >= 0 then Color.green else Color.red);
plot xavg = avg;
plot xheight = height;
plot ZeroLine = 0;

addlabel(1,"Plot is the tangent angle of the " + length + "-bar " + If averageType == AverageType.EXPONENTIAL then "Exponential average"
else if  averageType == AverageType.Hull then "Hull average"
else if averageType == AverageType.simple then "Simple average"
else if averageType == AverageType.wilders then "Wilders average"
else if averageType == AverageType.weighted then "Weighted average"
else "" ,color.white);

Comment: In the label, note the retrieval of the literal AverageType selection. The code shown is very reusable.
Comment2: This plot follows a trend very well
