How can I remove plot markers at some data points?
For example, I want to remove one plot marker at the circled point leaving only one marker there.
I tried deleting the data points but this would also delete part of the lines which is not wanted.
It would be good if I can input the data points where the markers should be removed. Assume that I already know the coordinate (data points) of these to be removed markers.

enter image description here

    (*Load the package code*)
    package = 
      Import["http://raw.github.com/AlexeyPopkov/PolygonPlotMarkers/\
    master/PolygonPlotMarkers.m", "Text"];
    
    (*Install the package (existing file will be overwritten!)*)
    Export[FileNameJoin[{$UserBaseDirectory, "Applications", 
        "PolygonPlotMarkers.m"}], package, "Text"];
    Needs["PolygonPlotMarkers`"]

    data = {Table[{x, 1 + 2 x}, {x, 0, 5, 1}], 
       Table[{x, 1 + x}, {x, 0, 5, 1}]} ;
    markers = {"Circle", "ThreePointedStar"};
    colors = {Blue, Red};
    Graphics[Table[{colors[[i]], Line[data[[i]]], FaceForm[White], 
       EdgeForm[{colors[[i]], AbsoluteThickness[2], JoinForm["Miter"]}], 
       PolygonMarker[markers[[i]], Offset[7], data[[i]]]}, {i, 
       Length[data]}], AspectRatio -> 1/2, ImageSize -> 450, 
     Frame -> True]


My orginal problem:

I want to remove markers at these points keeping only one markers there. enter image description here

    data = Table[{x, BesselJ[k, x]}, {k, 0, 4}, {x, 0, 10, 0.5}];
    markers = {"Circle", "ThreePointedStar", "FourPointedStar", 
       "FivePointedStar", "Circle"};
    colors = {Blue, Red, Darker@Green, Darker@Yellow, Orange};
    Graphics[Table[{colors[[i]], Line[data[[i]]], FaceForm[White],

  • $\begingroup$ Have you Tried ListPlot!? it's easier to work with PolygonMarker resources.wolframcloud.com/FunctionRepository/resources/… $\endgroup$

  • $\begingroup$ @Alrubaie not yet, would it work if I want to remove some markers? $\endgroup$

  • $\begingroup$ it's better and easier handling PolygonMarker inside ListPlot function. Check the link!!! part: Create a tuned up Graphics marker in one step: In[4]:= mtps = ResourceFunction["PolygonMarker"][ "ThreePointedStar", {Offset[7], 0}, {EdgeForm[Red], FaceForm[None]}] $\endgroup$

  • $\begingroup$ @Alrubaie I read that link before and my code above is basically from there. But my main goal is to remove markers at some specific points. $\endgroup$

  • $\begingroup$ @Alrubaie I think you misunderstood my question. I want to remove markers at some points instead of changing to a different marker's types. $\endgroup$

$\begingroup$ 
data = {Table[{x, 1 + 2 x}, {x, 0, 5, 1}], 
   Table[{x, 1 + x}, {x, 0, 5, 1}]};

colors = {Blue, Red};

markers = MapThread[
 First @ ResourceFunction["PolygonMarker"][#, {Offset[7], 0}, {EdgeForm[#2], FaceForm[White]}]&,
 {{"Circle", "ThreePointedStar"}, colors}];

Graphics[Table[{colors[[i]], Line[data[[i]]], FaceForm[White], 
   EdgeForm[{colors[[i]], AbsoluteThickness[2], JoinForm["Miter"]}],

  • $\begingroup$ Thanks, I got this error Syntax::sntxb: Expression cannot begin with "[PolygonMarker][#,{Offset[7],0},{EdgeForm[#2],FaceForm[White]}]". $\endgroup$

  • $\begingroup$ What would I modify if there is more than 2 overlapping markers at one place and in some places? $\endgroup$

  • $\begingroup$ The markers is giving me errors but I don't know what should it be like to modify it. $\endgroup$

    $\begingroup$ @kglr I've edited the answer to add what I think was a missing call to ResourceFunction that was causing the syntax error. Feel free to revert if I've misinterpreted. $\endgroup$
