Weird gnuplot behaviour removing data points

I want to plot a file that contains data like this (test1.txt):
1 10
2 5
4 6
12 11
13 5
17 9
where the first column would be the x axis values and the second column the y axis values. I would like gnuplot to output a histogram for these values.
I'm using the command:
set terminal svg size 1500,1000 enhanced font "Verdana,20"
set output "test.svg"
plot 'test1.txt' using 2:xtic(1) with histogram linecolor rgb "#00FF00"
quit
I'm getting a histogram as expected but some values are missing. For example (2,5).
What is going on?
UPDATE:
As noted in the comments, changing the range to [1:20] for the y axis fixed the problem. However, I would like each of the values on the y to have a corresponding label on the axis. Using ytic(2) results in very weird results.

It looks like they’re not missing, but just shifted off the display.  Your Y axis goes from 5 to 11, and the missing values are both 5, so they look like 0.  Fix your Y axis and let us know what happens.  I can’t tell you how to do that because I don’t know gnuplot (but, if it were my problem, I’d try adding a “0,0†data point).

@G-Man thanks, now I know the problem. However I would still like every y value to have a corresponding label on the axis, which doesn't happen by default if I manually set the range.

Do you mean you usedusing 2:xtic(1):ytic(2)? By the way, you might like to useset style fill solidto get more visible filled-in histograms.

@meuh Yes, I used that command. However when I use it, the range of the y axis goes back to [5:11] and I have the same problems as before.

set yrange [1:20]with the above:ytic(2)worked for me. gnuplot 5.0 patchlevel 1. why not update your question and image with the new contents of your file.
