Hi, first of all, thanks, is a great module. I'm using Version 2.4.1. There is a small flaw concerning imagemap_dump in Chart::Lines and Chart::Composite. The endmost value of the input data array never will be shown in the imagemap_data array. I checked the source and found: in Chart::Lines near line 110: *# draw every line for this dataset for $j (1..$self->{'num_datapoints'}) {* should better be written as: *# draw every line for this dataset for $j (1..$self->{'num_datapoints'}-1) {* because $self->{'num_datapoints'} is the number of elements in the array. and ... vice versa ... in Chart::Composite near line 81: *for $j (0..$#{$self->{'sub_0'}->{'imagemap_data'}->[$i]}-1) {* should better be written as: *for $j (0..$#{$self->{'sub_0'}->{'imagemap_data'}->[$i]}) {* and also line 88: * for $j (0..$#{$self->{'sub_1'}->{'imagemap_data'}->[$i]}-1) {* should better be: *for $j (0..$#{$self->{'sub_1'}->{'imagemap_data'}->[$i]}) {* because $#{$self->{'sub_0/1'}->{'imagemap_data'}->[$i]} is the number of the last element in array and should also be appended to the imagemap_data array. An example output with my modified Chart::Lines/Composite Modules can be shown at http://www.zweiernet.ch/wetter . As you can see It shows also the endmost data value as an over_popup based on the imagemap_data. Peter <pss-at-zweiernet.ch>
