Plot second highest

[tatl]

I need a way to get the highest, second highest, third highest, fourth highest, etc of a variable. let's say its volume for simplicity.

I need a way to get the highest, second highest, third highest, fourth highest, etc of a variable. let's say its volume for simplicity.

find the nth highest volume.
can pick a ranking of 1 to 5.
draws a triangle on nth volume bar
can draw a horizontal line at the volume level

# xth_highest_vol_00

#Plot second highest

def na = double.nan;
def bn = barnumber();

def v = volume;

input nth_highest_vol = 2;
#hint nth_highest_vol: Enter a number 1 to 5 , to find the nth highest volume

def hi1 = HighestAll(v);
def hi2 = HighestAll(if v < hi1 then v else 0);
def hi3 = HighestAll(if v < hi2 then v else 0);
def hi4 = HighestAll(if v < hi3 then v else 0);
def hi5 = HighestAll(if v < hi4 then v else 0);


def vx = if nth_highest_vol == 1 then hi1
 else if nth_highest_vol == 2 then hi2
 else if nth_highest_vol == 3 then hi3
 else if nth_highest_vol == 4 then hi4
 else if nth_highest_vol == 5 then hi5
 else 0;

plot vz = if vx == v then v else na;
vz.SetPaintingStrategy(PaintingStrategy.TRIANGLES);
vz.SetDefaultColor(Color.yellow);
vz.setlineweight(3);
vz.hidebubble();

input show_horz_line = yes;
plot zline = if show_horz_line then vx else na;
zline.SetDefaultColor(Color.yellow);
zline.hidebubble();

set to 4, find the 4th highest volume
draw a line at that volume level
