Hi, I wanted to make the graph with alpha property and it seem to have trouble with it.

Here is my code:

```
Mean <- 0#mean(x)
SD <- 1#sd(x)
tblCol <- c(
"#001010",
"#002020",
"#003131",
"#004141",
"#005252",
"#006262",
"#007373",
"#008383",
"#009494",
"#00A4A4",
"#00B4B4",
"#00C5C5",
"#00D5D5",
"#00E6E6",
"#00F6F6",
"#08FFFF"
)
Critical_Value <- qnorm(p = c(0,
pnorm(q = -3, mean = Mean, sd = SD, lower.tail = TRUE),
pnorm(q = -2, mean = Mean, sd = SD, lower.tail = TRUE),
pnorm(q = -1, mean = Mean, sd = SD, lower.tail = TRUE),
pnorm(q = 0, mean = Mean, sd = SD, lower.tail = TRUE),
pnorm(q = 1, mean = Mean, sd = SD, lower.tail = TRUE),
pnorm(q = 2, mean = Mean, sd = SD, lower.tail = TRUE),
pnorm(q = 3, mean = Mean, sd = SD, lower.tail = TRUE),
1), mean = Mean, sd = SD)
df_Normal_Distribution <- data.frame(Z_Score = seq(from = -4, to = 4, by = 0.01))
df_Normal_Distribution %>%
ggplot(mapping = aes(x = Z_Score)) +
stat_function(
n = 801,
fun = dnorm,
args = list(mean = Mean, sd = SD),
geom = "area",
color = alpha(tblCol[4], 0.785),
aes(
fill = after_stat(Z_Score) |> cut(!!Critical_Value),
group = after_scale(fill)
)
) +
labs(title = "Cumulative Density Distribution",
x = "Z_Score",
y = "Probability Density") +
guides(fill = "none") +
scale_fill_manual(values = c(alpha("firebrick2", 0.785),
alpha(tblCol[10], 0.785),
alpha(tblCol[12], 0.785),
alpha(tblCol[14], 0.785),
alpha(tblCol[14], 0.785),
alpha(tblCol[12], 0.785),
alpha(tblCol[10], 0.785),
alpha("firebrick1", 0.785))) +
```

Is there any way to make it more smooth?

If the ending colors ever match they get along together for some kind of reason, is there something wrong?
