--- Begin Message ---Package: libchart-perl Version: 2.2-1 Severity: normal Hello Stephen, I am trying to migrate from the woody version to this version and I have problems. The first I managed to identify is that setting max_val to a non-integral value break ticks: ------ lines.pl--------- #! /usr/bin/perl -w use Chart::Lines $obj=Chart::Lines->new; $obj->add_dataset('foo'); for($i=0;$i<$ARGV[0];$i++) { $obj->add_dataset($i); } $obj->set ('max_val' => 11.1); $obj->png ("foo.png"); ------------------------- I get : $ perl lines.pl 5 Chart::Base : Caution: Tick limit of 100 exceeded. Backing of to an interval of 0.02 which plots 57 ticks The second problem is that the colors used are different from the woody version (and less readable), but I am not sure why.

Backing of to an interval > of 0.02 which plots 57 ticks Hi, I think this problem can be considered fixed in the current libchart-perl version, 2.4.1-1. The error message doesn't occur any more, and there are now variables 'min_y_ticks' and 'max_y_ticks' that control the number of ticks: 'min_y_ticks' Sets the minimum number of y_ticks to draw when generating a scale. Default is 6, The minimum is 2. 'max_y_ticks' Sets the maximum number of y_ticks to draw when generating a scale. Default is 100. This limit is used to avoid ploting an unreasonably large number of ticks if non-round values are used for the min_val and max_val. The value for 'max_y_ticks' should be at least 5 times larger than 'min_y_ticks'. By setting min_y_ticks=2 and max_y_ticks=10, your example with max_val=11.1 gets ticks of 2 units each, ranging from 0 to 12. This behaviour seems sensible to me. I see no way to reproduce the exact woody behaviour with 2.22-unit ticks, though. > The second problem is that the colors used are different from the woody > version (and less readable), but I am not sure why. If you think this needs fixing, could you please provide an example? Anyway, color selections are more a matter of taste, I suppose, as long as they can be overridden explicitly (which seems to be the case here). As the primary issue here ('floating-point value for max_val option is broken') is IMO fixed, I'm closing the bug. Please feel free to reply/reopen if you think this is inappropriate.
