Bug. Data get filter twice with psevents -q0:inc:

[Esteban82]

With the improve version of animation 1 (#8459) I use the -q option to plot every 10 values (so I can avoid creating the point_sin.txt file).

I add -qi0:10: to events and I the values of 90, 190, 290 were plot (so every 100th value starting in 0). If I use plot instead, then I got the image ok.

gmt plot     sin_curve.txt -Sc0.3 -Gyellow -qi0:10:${MOVIE_FRAME}
gmt events sin_curve.txt -i0,1,0 -T${MOVIE_FRAME} -Sc0.2c -Gdarkred -qi0:10: -Vi

In the terminal, I got this message:
events [INFORMATION]: Events read: 37 Event symbols plotted: 35 Event labels plotted: 0

So, it thinks that 35 symbols were plotted (as gmt plot did) but there are only 3.

I suspect the events uses plot under the hood. And the data is filter by both modules. I tried to understand if this really happens (and where) but I couldn't. If someone could give a hint, I could try to solve it.

Full script:

# 1. Create files needed in the loop
cat << 'EOF' > pre.sh
gmt math -T0/360/1 T SIND = sin_curve.txt
gmt begin
	gmt basemap -R0/360/-1.2/1.6 -JX22c/11.5c -X1c -Y1c \
	-BWSne+glightskyblue -Bxagf -Bya0.5f0.1g1 --FONT_ANNOT_PRIMARY=9p
gmt end
EOF
# 2. Set up the main frame script
cat << 'EOF' > main.sh
gmt begin
	gmt basemap -R0/360/-1.2/1.6 -JX22c/11.5c -X1c -Y1c -B+n
	i=10
	gmt plot   sin_curve.txt -Sc0.3 -Gyellow -qi0:$i:${MOVIE_FRAME}
	gmt events sin_curve.txt -i0,1,0 -T${MOVIE_FRAME} -Sc0.2c -Gdarkred -qi0:$i: -Vi
	
gmt end

# 3. Run the movie
