sas不清楚，R软件是可以的

请问有人知道吗

If I can assume you produce bitmap format figure with high resolution, you can use below GOPTIONS:
XMAX, YMAX, XPIXELS, and YPIXELS

As you are asking for 600DPI, you can use below options(I use PNG as the example, unit is INCH):

GOPTIONS DEV = png XPIXELS = 2400 YPIXELS = 1800 XMAX = 4 in YMAX = 3 in;

The number in XPIXELS divided by the number in XMAX (XPIXELS/XMAX) is the DPI number and should be the same as YPIXELS/YMAX.

Good luck to you.

Thanks,

sgplot可以

当然可以，用ods输出的时候在绘图过程步前面加上ods listing image_dpi=600;即可，如果想了解更多SAS绘图的强大功能，请关注公众号：SAS可视化编程
