compressing space between 0 to 1

[mbarcala]

Im working on an lower indicator and I would like to know how I can manipulate the space between 0 to 1 and 0 to -1, I think that it can be done using the Log function but I can't find examples of this idea. I have a picture here that show two indicators space, my is the one on the bottom and I would like to make the space between 0 to 1 as the one on the top.

Your post is confusing, i am not sure what you are wanting.

1. Do you currently have values that range from -0.5 to 0.5 ?
with a full height span of 1.0?

2. Do you want to rescale your numbers, so they go from -1 to 1 ?
the center line would be the same, 0.
so multiply your variable * 2.

3. Do you want to rescale your numbers so they go from 0 to 1?
This would have the same height as your original series, 1.
need to shift the center line to 0.5,
so add 0.5 to your variable.

2. yes I want to rescale the numbers to go from 0 to 1. I'm using the stochasticFull but shows me 1 to far from 0 and I don't know how to de-scale that part. I don't have an idea how to code that part, can you show me a line so I can understand?

here is my code

declare lower;

input KPeriod = 20;
input slowing_period = 6;
input averageType = AverageType.EXPONENTIAL;

def lowest_k = Lowest(low, KPeriod);
def c1 = close - lowest_k;
def c2 = Highest(high, KPeriod) - lowest_k;
def FastK = if c2 != 0 then c1 / c2 * 100 else 0;

def FullK = MovingAverage(averageType, FastK, slowing_period);
plot FullD = MovingAverage(averageType, FullK, 3);

plot centerLine = 0;
