perlquestion reaper9187 Hi Everyone .. <br/> Back here to seek your wisdom on a particular issue. I'm trying to develop a time based analysis of a system monitoring certain parameters. I need to display the information using line graphs. I'm currently using Tk::Chart for this purpose. As it turns out , evry line graph i will be plotting is a function of three variables(say A,B,C). <br/> As you all must be aware, Tk::Chart only uses array references for displaying data( assuming the hash references do not exist), i need to customize my data accordingly. <br/> I'm trying to create an array of 2D arrays, something like <code>push(@{($a[$i])[$j][$k]},,44,55,66,22); #but this is not allowed </code> <br/> For eg: @a = qw/1 2 3 4 5/; , where each element has a 2D array associated with it .. <br/><br/> please help ..!!
