Hello,
I would like to create a simple but specific kind of plot for my protocol.
The data originates from protein chromatography and contains:
- the uv-absorption of substances/proteins within the solution - usally the Y-Axis,
- the volume that has gone throught the system - in my case the X-Axis,
- and fractioning of specific amounts of volume, starting at a specific moment
I can easily create a plot containing the first two rows of data. Now I would like to introduce a second X-Axis into the plot, preferably at the top or above the normal (first) X-Axis, showing the fractioning in respect to the first X-Axis, maybe drawling straight lines, creating columns that are called "FractionX".
I hope the description of what I would like to do is sufficient.
My question of course is: How do I add a second X-Axis which contains 2 rows of data.
The data looks like this by the way:
Column Y1 shows the start of the first fractioning in ml, 50.050, 50.060, et.
Column Y2 shows the fraction-name, F1, F2, etc.
Hope some one can give me a soltuion to this. :) |

Thank you for the answer but the solution in the link does not help me.
To further explain what I need, here is a picture:
This image was made with paint where I copy-pasted one axis onto another.
Have yet to figure how to do that. Does anybody know?
Again to explain: The upper axis shows fractioning at specific ml-marks, starting around 30ml and going till 60ml, I want those marks to be named as TX to TXX and so on. Cant be that hard, can it?
Thanks in advance! |

Hello, this issue has been resolved by email.
Basically add topX layer (2nd layer). On Scale tab, set Major ticks from the column with x values. And then on Tick Labels tab, set Type to be Text from dataset and specify the column with "T.." texts.

Thanks, Snow
