I would like to generate a chart from a dataset and eventually put it in a pdf format. How would I go about doing this? Which packages would you recommend?

回答1:

A solution might to go in two steps :

• first, generate the chart, and save it as an image
• then, embed this image in a PDF file

About the first point, there are many questions/answers that might help you ; for instance :

• Graphs/Charts in PHP
• What is the best open source PHP charting solution
• Free Chart Libraries for PHP
• References on creating Charts/Graphs in PHP ?

About the second point, I've not done that quite often, but I suppose Zend_Pdf, for instance, could be helpful -- note there are probably other solutions too !

回答2:

I would look into these:

• gChartPHP
• pChart

• Open Flash Chart

• Dynamically Generate PDF file with PHP

回答3:

Take a look at the Diagrams AddOn for fpdf.
I've never used it but would give it a try before storing a raster image of a chart in a pdf.

回答4:

You can insert charts in PDF as an image too.
Google's Image Charts is deprecated but still works.
A ditto copy of Google's Image Charts is Image Charts which has free version with their watermark.
