My question is this: I would reproduce the screen of a graphic calculator like the image below:

https://services.math.duke.edu/education/prep02/teams/prep-16/tivertex_files/image006.gif

what might be the possible solutions?

I use LaTeX (related question) and I remember that there was a specific package. Now supposing that I use the package tipfr-doc.pdf, the graph

enter image description here

is incomplete. In fact it is without pixel and labels. I have download the fonts Texas Instruments and I complete the drawing?

What are the suggestions how to quickly create a file vectorial .pdf similar to the initial image?

Thank you very much to all users. I hope that someone might help me.

    You could also check videos/articles about Pixel art on Adobe illustrator: design.tutsplus.com/tutorials/…

    Not asked, but I like to have my graphs as sharp. The crunched and already deleted answer showed an easy way to get them.

If you do not have TI-85 emulator draw it as pixel art as suggested already by others or create it in LaTeX as you have already done.

When you have a bitmap image like the black one vectorize it.

Start in GIMP or Photoshop by increasing the pixel dimensions to Nx100%, at least to 400% with nearest neighbour resampling for no blur. Paste the result to Illustrator and trace it with the highest accuracy:

enter image description here

In small size it looks good but in bigger size it's far from perfect:

enter image description here

Apply Object > Live Trace > Expand and Object > Path > Simplify to get perfect straight edges. See the dialog:

enter image description here

Now it's like the original, but sharp also in high zoom. The rightmost is the vectorized version. I Ungrouped it and changed the fill color of a part just to show it's a vector:

    I haven't one. My calculator emulator tries to be a HP's postfix notation model. I prefer that system to keep things in order. But start by checking this video youtube.com/watch?v=lXIqazmkFwo . It shows that setting up a TI-85 emulator needs much more than downloading a program & running it.

    @Sebastiano The preceding comment by user joojaa should be taken seriously. Applying in Illustrator Object > Create Object Mosaic, size=the image pixel dimensions does the job if you have a machine from this century. Ungroup, select one white rectangle, apply Select > Same > Fill color and press DEL to kill the unnecessary white objects.

    @Sebastiano seemingly you also want somehow realistic look. It's easy if you can make layered images. Open this dropbox.com/s/qc2d5vqlsob0dfp/calculator.psd?dl=0 in GIMP, Photoshop or Photopea and see the layers. They are from the top the formula (=crap), partially transparent blurred and moved copy as a shadow and a gradient background for realistic light.
