linux - display.im6: no decode delegate for this image format `/tmp/magick-KFcbfWUi' -

i'm using rio , have sample.csv looks following

hour,count 0300,0 0300,0 0300,1 0300,1 0300,2 0301,1 0301,2 0301,2 0301,3 

i run following command:

$ < sample.csv rio -ge 'g + geom_bar(df, aes(hour, count))' | display

and

display.im6: no decode delegate image format `/tmp/magick-gvr3krzh' @ error/constitute.c/readimage/544. 

from know geom_bar expects dataset first df , columns, i'm not sure why don't see graph, knows missing?

thanks

see docs.ggplot2.org/0.9.3.1/geom_bar.html. expects mapping first, data. , don't have specify df data, because it's been captured in g.

and think need specify stat='identity' if want specify y aesthetic.
