Origin Ver. and Service Release (Select Help-->About Origin): 8
Operating System: WinXP
Hi all,
I am trying to plot a chromatogram of absorbance in Y axis and the volume in the X-axis. I also want to labels to a range of X values. For instance, if my X axis goes from 0->25ml, I want to add "Fraction 1" to a range of 0->2ml, fraction 2 to 2ml->4ml etc.
The problem is that I can't find a way to add multiple X values or set a range for a label.
Appreciate your help,
Chen |

Hi Chen,
Thank you for contacting us. The first step: double click on the X axes to open the X Axis dialog, and then choose scale, setting From 0 To 25, the increment is set to 2, click OK button. The second step: Add a new column in your worksheet. For example, you want to add ¡°Fraction 1¡± to ¡±Fraction 10¡± to your graph, please input ¡±Fraction 1¡± ¡±Fraction 2¡±¡¡±Fraction 10¡± in the new column from Row 1 to Row 10. The third step: active the graph page, choose Graph>>New Layer>>Bottom-X Left-Y then delete the new Y axes, and repeat the first step on the new X axes. Click Tick Labels, set Type to Tick-indexed datas, choose the new column as the Dataset, click OK button. The last step: Double click on the graph to open the Plot Details, choose Link Axes Scales, set Link to Layer1, choose Custom as X Axis Link, X1=X1-1, X2=X2-1. At last double click on the new x axes, choose Title&Format, uncheck the Show Axis&Ticks.
Best regards
Yours sincerely
Alex
