## Issue

I have this code in gnuplot to plot the mean.

The problem is that the value is very low like 0.00000000000000001.

I woul like to plot it in scientific notation, but i have this error if i try to follow the set format guide.

Thank you!

Code that I have:

```
stats filename u ($1*$2):2 nooutput
mean = STATS_sum_x/STATS_sum_y
set arrow 1 from mean, graph 0 to mean, graph 1 nohead lw 2 lc rgb "red" front
set label 1 sprintf("Mean: %8.6f", mean) at mean, graph 1 offset 1,-0.7
```

Code if I try to have scientific notation:

```
stats filename u ($1*$2):2 nooutput
mean = STATS_sum_x/STATS_sum_y
set arrow 1 from mean, graph 0 to mean, graph 1 nohead lw 2 lc rgb "red" front
set label 1 sprintf("Mean: %s*10^{%S}", mean) at mean, graph 1 offset 1,-0.7
```

Error:

```
f_sprintf: attempt to print numeric value with string format
```

Thank you !

## Solution

I am also a bit confused about the documentation for `help format_specifiers`

.

Check `help gprintf`

and try using `gprintf()`

instead of `sprintf()`

. Maybe the following is using `%h`

is also fine for you.

**Code:**

```
reset session
mean = 0.00000000000000001 # or 1e-17
set label 1 gprintf("Mean: %h", mean)
plot x
```

**Result:**
