具有良好分辨率的绘图用于打印和屏幕显示 [英] Plots with good resolution for printing and screen display

问题描述

我正在使用

dev.new(width=5.8, height=3) 
par(mfrow=c(1,3),mar=c(1,1,2,1),oma=c(4,1,2,0),mgp=c(3, 0.5, 0)) 
plot(...)

并将它们复制并粘贴到 Microsoft Word 中.它们在 Word 中看起来非常好(我尝试了不同的宽度，直到找到一种效果很好的宽度)但是当我打印它们时，它们看起来很糟糕.经过一些网络搜索，我发现打印分辨率至少应为 300ppi.因此，在永远摆弄宽度和高度之后，我得出了使绘图看起来相同大小但分辨率更高的代码:

and coping and pasting them into Microsoft Word. They look really good in Word (I tried different widths until I found one that worked well) but when I printed them they looked terrible. After some web searching I found the resolution for printing should be at least 300ppi. So after fiddling with widths and heights for an eternity I came out with code that makes the plots look the same size but with a better resolution:

png(file="mag_feb.png",width=1800,height=950,res=300)

它们现在在打印时看起来不错，但在 Word(在屏幕上)中看起来一点也不清晰.会不会是尺寸的问题?没有办法让图表在印刷和屏幕上看起来都很好吗?我已经花了几个小时来解决这个问题，想不出还有什么可以尝试的，所以非常感谢任何帮助！

They now look good when printed, but they don't look sharp at all in Word (on screen). Could it be a problem with size? Isn't there a way to make graphs that look good printed and on screen? I already spent hours with this and can't think of anything else to try, so any help will be very much appreciated!

谢谢！

推荐答案

您的原始 png 命令中有一个小错误.试试这个:

There is a small error in your original png command. Try this:

png(file="mag_feb.png", units="in", width=11, height=8.5, res=300)

现在，宽度和高度以英寸为单位，而 res 以像素/英寸为单位.之前，res 参数被忽略.

Now, width and height are in inches, and res is in pixels/inch. Before, the res parameter was being ignored.
