  d.linegraph: Follow-up fixes for typos, dereference pointers, and format string precision specifier (#7722)

A couple simple string typos were fixed, plus two other issues.

`tt` and `tb` are pointer parameters (`double *tt`, `double *tb`), so `tt - tb` computes pointer difference (an address offset), not the difference between the pointed-to text box values. The condition should dereference the pointers: `(*tt - *tb) > YTIC_DIST`.

The format string `"%f.0"` is incorrect — the `.0` precision specifier must be inside the format specifier, not after it. The literal `.0` will be appended as plain text to the output. The intended format is `"%.0f"` to format the value as a float with no decimal places.
