vba - Excel Visual Basic Macro- Selecting data dynamically for a chart? -


so, question stupid, i'm not familiar excel vba. here's generated macro code imports data text file , graphs it.

sub getdata() ' ' getdata macro '  ' activesheet.querytables.add(connection:= _     "text;c:\data.txt", destination:=range("$d$3"))     .name = "data_2"     .fieldnames = true     .rownumbers = false     .filladjacentformulas = false     .preserveformatting = true     .refreshonfileopen = false     .refreshstyle = xlinsertdeletecells     .savepassword = false     .savedata = true     .adjustcolumnwidth = true     .refreshperiod = 0     .textfilepromptonrefresh = false     .textfileplatform = 437     .textfilestartrow = 1     .textfileparsetype = xldelimited     .textfiletextqualifier = xltextqualifierdoublequote     .textfileconsecutivedelimiter = false     .textfiletabdelimiter = false     .textfilesemicolondelimiter = false     .textfilecommadelimiter = true     .textfilespacedelimiter = false     .textfilecolumndatatypes = array(1, 1, 1, 1, 1)     .textfiletrailingminusnumbers = true     .refresh backgroundquery:=false end range("d3:h4").select activesheet.shapes.addchart.select activechart.charttype = xlxyscatter activechart.setsourcedata source:=range("sheet1!$d$3:$h$4") end sub

essentially, because data inputted data.txt can length, program not work; goes d3:h3. i'd chart use data d3 hx, x end of data row. how this? helping idiot!

probably following work: 

sub getdata() ...      .... end lastrowcolh = range("h65536").end(xlup).row activesheet.shapes.addchart.select activechart.charttype = xlxyscatter activechart.setsourcedata source:=range("sheet1!$d$3:$h$" & cstr(lastrowcolh))   end sub

hth!
