Description: ------------ Line 386 of /Image/Graph/Plot.php calculates the COLUMN_WIDTH of a marker point. This calculation currently does not properly take the absolute value of the X1 X2 difference due to a typo in PHP. Current code: $point['COLUMN_WIDTH'] = abs($point['MARKER_X2'] - ($point['MARKER_X1']) / count($this->_dataset)); Should be: $point['COLUMN_WIDTH'] = abs($point['MARKER_X2'] - $point['MARKER_X1']) / count($this->_dataset); This error causes markers to be placed at very random locations throughout the graph on a bar graph. This sample from your site demonstrates this issue as well: http://pear.veggerby.dk/samples/show/id/plot_bar_multiple/

A small executable test case will get you a lot further, I'd suggest.

This bug has been fixed in SVN. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better. Yes of course, you're right. Thank you for pointing that out.
