QGIS custom grid / line oriented point displacement?

I am trying to sort point symbols at the same coordinates in a line. The first picture shows how I want it to be (all symbols in a single horizontal line), the second how it looks with the standard grid-based point displacement (multiple, unwanted rows of symbols, and therefor also an unwanted overlap of text and symbols).
Is there any way/plugin to either change the parameters of how the grid is built (number of rows/lines) or any other way to show symbols in a line?
I am not hugely into scripting or programming though.

Welcome to GIS.SE, Tyak! Please keep in mind, that from a cartographical point of view this display of information is not desirable, since the exact location of the ruins can not be determined.

I agree that this is not an exact map, but since most of the stuff I am showing is only known from literature anyways I don't think that it'd matter much. Also: You gotta do what the boss wants you to do, so...^^

Sometimes telling your boss, that their ideas are bollocks, is the better solution ;-) could you tell some more about your data? Are the ruins all in one shape file? Are they separate points for each location, or do you have one point per city/site and then attributes?

they are all different points with the same coordinates on the same shape file.

I could put them into single points with attributes too if that woud help...

I would calculate offset distance (dx) for each feature, so that I can position them by (x, y) = ($x+dx, $y).
An example of expression to calculate dx is:
with_variable('my_array', array_agg("symbols", group_by:="geom_to_wkt($geometry)"),
5 *(array_find(@my_array, "symbols") - floor(array_length(@my_array)/2)))
- You will need to modify
"symbols"according to your attribute field which defines your categorized symbols. - The second line has a factor
5, but it is arbitrary. Please adjust this number by visually checking your output.

But wouldn't that give every symbol a fixed position? Wouldn't that result in gaps between symbols if some weren't there at a location?

@Tyak thearray_lengthpart counts the number of your symbols andarray_findchecks its position in the array. If you have many symbols the array is extended.
