Chart::Plot::Canvas is a Perl module to plot two dimensional data in an Tk Canvas. SYNOPSIS use Chart::Plot::Canvas; my $img = Chart::Plot::Canvas->new(); my $anotherImg = Chart::Plot::Canvas->new ($image_width, $image_height); $img->setData (@dataset) or die( $img->error() ); $img->setData (@xdataset, @ydataset); $img->setData (@anotherdataset, red_dashedline_points); $img->setData (@xanotherdataset, @yanotherdataset, Blue SolidLine NoPoints); my ($xmin, $ymin, $xmax, $ymax) = $img->getBounds(); $img->setGraphOptions (horGraphOffset => 75, vertGraphOffset => 100, title => My Graph Title, horAxisLabel => my X label, vertAxisLabel => my Y label ); print $img->draw(); $img->canvas($toplevel)->pack(); This package overloads Chart::Plot and supplies a new method canvas that returns a Tk Canvas equivalent to GD::Image returned by the method draw of Chart::Plot. The graphs are descripted by same way as for Chart::Plot. With Chart::Plot::Canvas, the method draw works like with Chart::Plot. USAGE See Chart::Plot for all over methods. Create the canvas: canvas() $img->canvas(toplevel); This method creates the canvas and returns it. use Chart::Plot::Canvas; my $img = Chart::Plot->new(); $img->setData (@xdataset, @ydataset); my $cv = $img->canvas($toplevel); $cv->pack();.
