xmgrace 可以生成一维图吗？

Question

Is it possible to get in xmgrace a 1D plot, ie, a line with an arrow in front of it, subdivided in labeled subregions by means of vertical bars? Thank you for your attention!

Answer 1

As I said in a comment, it is certainly possible, although not exactly comfortable.

• Open xmgrace , go to Plot -> Graph appearance... , select the Frame tab and set the line style to None .
• Go to Plot -> Axis properties... :
  • select the X axis and tick Zero axis . Untick Display tick labels and Display tick marks if you want to get rid of those.
  • select the Y axis and untick Display tick labels , Display tick marks and Display axis bar .

I don't think there is a straightforward way of having the axis end with an arrow, but you can add one from the Window -> Drawing objects dialog.

About the data: your file should have this format:

x0 0 1
x1 0 1
x2 0 1
x3 0 1
x4 0 1

where x0, x1, etc are the values at which you want to draw the vertical lines. Import your file via the Data -> Import -> ASCII... dialog, choosing XYDY as set type.

Now open the Plot -> Set appearance... dialog, select the set, set the line type to None and change the line color (which affects the bar lines). Go to Error bars and set Bar line to 0 and the Riser line to the width you want. If you want to rescale the height of the vertical lines open the Axis properties and change the scale of the Y axis. Here is an example of how the plot will look like at the end of this procedure:

As I said, it is a very cumbersome procedure but it can be done :-)
