Origin Version (Select Help-->About Origin): Origin 7.5
Operating System: Windows XP
Dear All
I have one X dataset ( for wavelength ), several Y datasets ( for absorbance, and each Y dataset corresponding to a different time value, like Y dataset 1 corresponding to 1 hour, Y dataset 2 corresponding to 6 hours, Y dataset 3 corresponding to 11 hours, etc). I want to plot the graphy in one figure (X-Y), But I don't want the Y datasets overlapped, I want each Y daset shift to the right (or left) a little bit to the previous Y dataset, so I can tell easily which graph correspond to what time. The final figure may look like a 3D.
I am not sure if I explain the question clearly. Could anyone please help me how to do this? |

This can be done by selecting Plot> Special Line/Symbol> WaterFall.

Thank you very much for your help. That's exactly what I want. Now, if I want to add the Time as the third axis (see, wavelength as X, Time as Y, and absorbance as Z) to get sth like the following graph
Could you please show me how to do that? Thank you very much! |

Use Plot > 3D XYY > 3D Waterfall to create a 3D graph like Graph1 below. Y and Z axes are swapped but you will want to change their titles anyway. To label the Z axis (Time) ticks double-click on their current values and set their Type to Numeric. Then go to the Scale tab and adjust the From and To values as well as the tick increment.

Thank you very much for your help. I hope this is the last question:
3D XYY waterfall can only be applicable to X-Y datasets (in my case, X dataset as wavelength, Y datssets as absorbance, time is only a symbol but not a true axis) , if I want to add the third axis for time, I have to do XYZ plot, in that case, how I can get a similar graph as what I do with XYY waterfall?
Thank you! |

Seems you do not need a third axis. Just adding some labels for the curves is fine. you can see this pseudo 3D effect from here.

Is this the style that you need?

| Well, I am just curious. In fact the example Mike shows is better for me. I am just wondering what if happen in XYZ. Thanks! |

When you create the 3D waterfall plot the "Time" axis ticks are labeled by the corresponding column names. Double-click on those tick labels and change them in the resulting dialog. In Graph1 the true tick values are 1, 2, 3, ..., 16 but I wanted to show half of them to make the graph look tidier. That was accomplished like this...
1. Change the Tick Labels tab as shown here. (Change Type from Column Headings to Numeric.)
2. Configure the Scale tab as shown here.
3. Add axis title on the Title & Format tab.
