how the data

I am having a point data of in total of 13 destinations within a region. The goal is to present how many people who were in destination "A" also visited the other 12 destinations.

I have this data calculated both in relative and absolute figures. Now, I want to show it on the map.

The data represents relations for a destination X, "Dub". Where Dub and Dub cross, there is an absolute number of visits for that one destination. The other crossings, eg. Dub-Zad, is a percentage of people that, out of those 316 people, also visited Zad (14% or ca. 51). This is all within one region. Now, I want to map this so the line between Zad-Dub is eg. 1.4, Dub-Spl 3.4, Dub-Mak 0.3 and so on. I have, naturally, the coordinates for all of the destinations.

I hope I am more clear now. So, as I said, I have coordinates of those destinations but I don't know how should then the data look and how to use the data to connect the dots the way I want to.

    Welcome to GIS.SE. Could you provide a subset of your attribute table? Also, please decide whether you want to do this in QGIS or ArcGIS. – Erik Oct 21 at 15:43
  • Thank you. At this moment, I don't have a subset, I have the data that is described a bit up there. But, it would be something like this: – Timorche Oct 21 at 15:48
  • 9 9 13 34 5 12 12 5 524 11 – Timorche Oct 21 at 15:49
  • Please, forgive my comments before. Anyway, QGIS is better. So, I have the total number of visits to a destination (524 up there) and those smaller numbers are percentage how many people visited both destination A and that other destination. – Timorche Oct 21 at 15:50

    Sorry, I dont understand your example. Can you provide one complete example in your question? Are the total visits linked to coordinates? – MrXsquared Oct 21 at 15:52

Use an attribute field or expression to define your stroke width:

enter image description here

As your numbers are likely going to be too large to be used as a width, under the Expression submenu, select Edit to create a new expression. You can use the field that has your count value and multiply it by say 0.1, for example, to bring it down to a more realistic number that can be used as a width.


Since I didn't figure it out, I eventually just made lines from the X place to the other 12 places. I added the attribute of thickness, based on the aforementioned percentage of visits (2% = 0.2, 38% = 3.8 and so on). However, this is only applicable when there aren't too many trajectories/lines needed. If anyone knows how to connect points to make lines with special attributes, feel free to post it here.
