-

i'm trying plot graph in scroll area i've no idea how change size of graphs. here example of have:

enter image description here

as can see, in scrollarea (in red) size want, have graph (well, in reallity have more graphs , want see more 1 (at least two) in area).

so, want height of graph (a) smaller , width of graph (b) expanding. somine can me ?

thanks !

it looks plot inside layout "hide emg" button. widget holding layout must resized fit scroll area. you'll need provide code sample if want more that..

also consider using pg.multiplotwidget, provides similar functionality.

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).
