Pixel size ?

Hi all,

a quickie - when generating PNG/JPG/PDF from a chart, the graph size is supplied in pixels. First of all - how big is a JFreeChart pixel (in mm) ? Secondly - is the size specific to JFreeChart or in any way standardized ?

Thanks in advance

Hi,

this is the Java standard way: One pixel is 1/72 inch, the standard graphics resolution in java. All (unscaled) graphics operations work with this resolution.

For printering, a higher resolution is used for printing, all coordinates are transformed to fit the output target.

Have more fun,
