How to create this chart in Numbers?

I do appreciate your kindness reply.
Please let me repost my question and express my concern again
I look forward from you guys.^^ I do need your help!
Thanks again.

<<Question repost>>
for example:

Assume we have 10 (x, y) pairs as below:
(10,10), (12,23), (47,9), (63,24), (88,100), (150,41) ,(155,166), (188,2), (198,58) and (500,200). Each (x,y) pair is a single point in the graph.
If we use Scatter chart to handle these data, the output graph is fine but not suitable for me to use.
I wish there will be a trend line between two of each independent points of Scatter graph, and obtain a graph just like the output graph as used in Line chart (line+symbol).

That is, in Line chart, the values of x-axis(with equal-width intervals) are categorical; however, my data is ordinal value or continuous value (like Time, Concentration...etc.). I wish this software has the ability to show the interaction between each points.

First of things, I am really appreciate your kindness.
Please let me repost my question again by sample and clear.

My key-point is that the data always be defined like independent parameter and no mater how distance was change (ex: 10 to 20, distance is 10 unit; 20 to 100, distance is 80), the interval was all the same in Line Chart.

How do I adjust x-axis to like relatively interval (distance, hours...etc.).
