Unexpected behavior in ListLinePlot?

I create an array of images with ListLinePlots. All that the images are are set of sets of 4 points forming 3 lines. I tried to arrange for my lines to use the full range of the frame with an aspect ratio of 1x1. I have it so that the X axis starts at the minimum value of the data and the Y axis starts at 0 while the top of the Frame is at the maximum Y. I've attached as simple notebook so that you can see how the images comes up properly. However, when I am plotting a number of such plots, most of them are printed correctly, spanning the range of [Ymin,Ymax] on the Y axis BUT some of them still show the chart with a lot of space below the Minimum Y and above the Maximum Y. Please see the attached notebook for more information:

Thank you Rohit. Your last suggestion worked! When I tried to Binarize, I received the error shown previously. I will try your code.

Oh, finally I think I get it. How about this?

plots = ListLinePlot[#,
    Background -> Black,
    ImageSize -> {128, 128},
    Frame -> False,
    Axes -> False,
    AspectRatio -> 1,
    PlotRange -> CoordinateBounds@#,
    PlotMarkers -> {{\[FilledCircle], 2}}] & /@ images

enter image description here

You can use Scaled if you want to add some padding so the plot markers are completely visible. Check the documentation for CoordinateBounds.

I found that Binarize doesn't produce an image with just 0's and 1's

How did you determine this?

If you are using a color sampler on the image rendered on a screen/monitor then that is the result of anti-aliasing in the display of the image, not the image itself.

There are only 0's and 1's in the image

plots // Map[Binarize /* ImageData /* Flatten /* Counts]
(* {<|0 -> 63554, 1 -> 1982|>, <|0 -> 63225, 1 -> 2311|>, <|0 -> 63500, 1 -> 2036|>} *)

Hello Rohit. Yes, the full range of data is plotted, but what you show in the last 3 binarized images is not what I wish for. In your last images, the Minimum Y coordinate (leftmost point in images 1, 3rd point in images 2 and 3) should be on the X axis (or as close as the graphics will allow) and the Maximum Y should be at the top of the image. I read up on this where, for instance there was an option to provide where the X and Y axes should intersect and (in my case that would be at the (Xmin,Ymin) location (which is not necessarily one of the points, see images 2 and 3). This would force the lowest point to sit on the X axis and the highest point to touch the top of the Chart. I absolutely don't want ant space above or below the 4 points. Also , since you are responding, I found that Binarize doesn't produce an image with just 0's and 1's, How can I make sure that the "Binarized" images I obtain are TRUE binary images with just 0's and 1's.

The full range of the data is plotted, it is the origin that is different. Is this what you are looking for?

plots = ListLinePlot[#,
   Background -> Black,
   ImageSize -> {128, 128},
   Frame -> True, 
   Axes -> False, 
   AspectRatio -> 1,
   PlotRange -> All,
   AxesOrigin -> {0, 0},
   PlotMarkers -> {{\[FilledCircle], 2}}] & /@ images

enter image description here

Regarding Binarize, it requires an Image or Graphics as input. Framed changes the Head to Framed. So, Binarize first, then add Framed.

plots = ListLinePlot[#,
    Background -> Black,
    ImageSize -> {128, 128},
    Frame -> False, 
    Axes -> False, 
    AspectRatio -> 1,
    PlotRange -> All,
    AxesOrigin -> {0, 0},
    PlotMarkers -> {{\[FilledCircle], 2}}] & /@ images

Binarize /* Framed /@ plots

I could, but I want to understand why a number of charts come out exactly as I want them (using the full range of the chart in the Y direction) while a few only use part of the Y range. For instance, I provide you with 3 sets of points, the ListLinePlot command I use on them and how they come out. Please take a look at the top of the notebook I provide. It is also about binarizing an image, but for now, I will be happy if I can consistently plot using the full range of the chart.

What about calculating Max[max1,max2,...] and the same for Min?
POSTED BY: Hans Dolhaine

This would work if I were just plotting a single image of 3 lines. But when I am plotting multiple lists of coordinates, each list will have a different min, max. So, calculating the mins and maxes for X and Y would only be valid for one of the lists of coordinates.

What about this?

pts = {{0, 217.3000030517578`}, {15, 158.83999633789062`}, {42, 
   248.83999633789062`}, {43, 237.8699951171875`}}

xmin = .8 Min[Transpose[pts][[1]]]
xmin = -5
xmax = 1.2 Max[Transpose[pts][[1]]]
ymin = .8 Min[Transpose[pts][[2]]]
ymax = 1.2 Max[Transpose[pts][[2]]]

Table[
 ListLinePlot[pts, ImageSize -> {128, 128}, Frame -> True, 
  Axes -> False, Ticks -> False, AspectRatio -> 1, 
  PlotMarkers -> {{\[FilledCircle], 8}},
  PlotRange -> {{xmin, xmax}, {ymin, ymax}}],
 {n, 1, Length[pts]}]
