PHPExcel Chart Axis Options set Minimum

由 牧云@^-^@ 提交于 2020-01-04 03:16:28
问题 I'm having an issue with PHPExcel that it is not PHPExcel's fault. In a graph, the values being presented are very large, so since the default setting for the axis options for Minimum is Automatic, Excel is deciding to use a minimum value for the Y axis of 156,000.

So I've been trying to figure out if you can set this option from within PHPExcel, but can't figure

Reading multiple files with PHPExcel

问题 I just recently started using this library (the one from CodePlex), but I ran into some issues. My goal is to use it so I can process some data from multiple Excel files, and send such data to a database, per file. I'm doing something like: foreach( $file_list as $file ) { $book = PHPExcel_IOFactory::load( $path . $file ); } So, inside the foreach I'm (for now) just showing the data to the user, but after five files, I get a memory error: Fatal error: Allowed memory size of 33554432 bytes
