Comment(by glynn):

 Replying to [ticket:1842 lucadelu]:

 > d.linegraph writes a pgm file instead of ppm and d.mon returns an error

 If the PNG driver is asked to generate a PPM file and the data has an
 alpha channel, it will generate both a .ppm file and a .pgm file. The .ppm
 file is written first, and a fatal error will be raised if the file cannot
 be opened (so the .pgm won't be created).

 If you have a .pgm file without a matching .ppm file, the most likely
 reason is that something has deleted the .ppm file.
