ggplot2 - R ggplot barplot separately for each year -

-

i know how barplot data separately each year. i'd add excel-image, couldn't cause i'm new in forum. have following data in data frame:

year    2009/10    2010/11    2011/12     2012/13    2013/14 v1     -221.85      0.00       0.00      -138.73     -191.10 v2       0.00     -223.16    -231.52       0.00      -126.85 v3       0.00     -1216.17   -1337.28    -1112.11    -863.98 v4       0.00     -520.87    -540.88     -174.85     -296.78 v5       0.00     -465.48    -805.63     -252.38     -178.92 v6       0.00     -496.25      0.00        0.00      -232.17 v7       0.00       0.00       0.00      -709.63     -759.41

please me - have tried different approaches without success.

many in advance

any ideas when firefox implement lengthadjust andtextlength?..... working svg application. lengthadjust , textlength working fine in chrome not working in fire fox . <svg viewbox = "0 0 500 300" version = "1.1"> <defs> <path id="s3" d="m 10,90 q 100,15 200,70" /> </defs> <g> <text font-size = "20"> <textpath xlink:href="#s3" textlength="205"> short text</textpath> </text> <use xlink:href="#s3" fill="none" stroke="black" stroke-width="1"/> </g> </svg> this implemented in firefox text elements (not textpath or tspan) in case that's ok though can move attribute text element. <svg viewbox = "0 0 500 300" version = "1.1"> <defs>

i using indy udp server read string of data. however, not know how work adata parameter. can around converting binary using bytetobin function below , convert hex using bintohex1 . feel stupid , works slow. know how can directly results without 2 conversions? thanks!! here codes: procedure tform1.idudpserver1udpread(athread: tidudplistenerthread; const adata: tidbytes; abinding: tidsockethandle); var buf: tidbytes; buffer: string; data_received: string; begin if bytestostring(adata) <> 'hello' begin buffer := hextostring('00'); setlength(buf, length(buffer)); copytidstring(buffer, buf, 0); abinding.sendto(abinding.peerip, abinding.peerport, buf); data_received := bintohex1(bytetobin(adata[1]) + bytetobin(adata[2]) + bytetobin(adata[3]) + bytetobin(adata[4]) + bytetobin(adata[5]) + bytetobin(adata[6]) + bytetobin(adata[7]) + bytetobin(adata[8]) + bytetobin(adata[9]) + bytetobin(adata[10]) + bytetobin(adata[11
