I have a chart in Excel, and I’d like to put it on a web page. The line I have plotted on the chart is very jagged. Is there anyway to get it to anti-alias it, like it would be in an Illustration program?
Can you make a screen capture of the chart and anti-alias it with your Illustration program (i.e. photoshop) in a subsequent step? Seems like that could be used on a web page.
That does kind of work. You can select the chart, hit Cut, and the Paste it into an image program and resize it. Not ideal though. I don’t like the way that vertical and horizontal lines get blurred, when they wouldn’t if Excel was handling it. And manually anti-aliasing text works much worse than letting the renderer do it. Very blurry.
Maybe I can get the chart into Illustrator or Photoshop somehow.
You can try two more things. First, is it possible for your display to use a higher resolution? If so set it as high as it goes and retry the screen shot. Failing that there are application which will let you increase the resolution by processing the image but I don’t know how far you can take that.
If the problem is truly aliasing then I can’t help you. But it may be worth a try to select the line, use menu Format, Selected Data Series, then check “Smoothed Line.” This will give you a line that smoothly curves through all the data points rather than a series of straight line segments.
This is a long shot because it might not appropriate for the type of data you’ve got.
