How to improve PNG picture resolution by jsl

Hi,JMPer

I'm using Mac version, and want to save some boxplot charts to PNG by jsl.

How to improve the PNG picture resolution?

 

I used below jsl and change resolution number, it sames not take effective.

graph1 <<SAVE picture=""></SAVE>

 

The resolution is not good as below.

For windows you could change the Save Image DPI preference value

 

Names Default To Here(1);
//Caution: Changing a preference will 
//affect the default behavior of JMP. 

Preferences[1] << Set(Save Image DPI(300));

but that seems to be Windows specific command. Not sure if the only option on mac would be to increase the image size before saving (it might help).

Resolution (DPI) for PNG and JPEG Images (windows specific preference) 

Using JMP > Save and Share Your Data > Save Reports > Set the Graphic DPI for Exported Graphics
