# Plot points with unknown column numbers

Hello
I am trying to plot points with unknown column numbers for instance: plot (fx,fy,'bo',ax(i,1),ay(i,1),'bo',ax(i,2),ay(i,2),'bo')
where fx and fy are not changing, however ay and ax will plot according the row and column number all on the same time. However, every time I will be getting n columns ranging from 1 to depends. I tried hold on but the points from the previous plot are there, in which i dont want.
is there a way that i can automate this code to generate a line as the code above with different column numbers every time ?
here is the full code figure(2) names = 1:1:rx; for i =1:1:rx name = i; plot (fx,fy,'bo',ax(i,1),ay(i,1),'bo',ax(i,2),ay(i,2),'bo') xlim([0 50]); ylim([0 50]); title(sprintf('%s Step: %i',sys,i)); pause (0.5) end
Thanks

Here's the fix, sorry it took a while. Got distracted ;)
figure(2)
names = 1:1:rx;
for i =1:1:rx
name = i;
plot (fx,fy,'bo')
xlim([0 50]);
ylim([0 50]);
hold on
for j = 1:scell
plot(ax(i,j),ay(i,j),'bo')
end
title(sprintf('%s Step: %i',sys,i));
pause (0.35)
hold off
end

did you turn hold back off?
figure(2)
names = 1:1:rx;
for i =1:1:rx
name = i;
plot (fx,fy,'bo')
xlim([0 50]);
ylim([0 50]);
hold on
for j = 1:size(ax,2)
plot(ax(i,j),ay(i,j),'bo')
title(sprintf('%s Step: %i',sys,i));
pause (0.5)
end
hold off
end

not quite, i emailed you the code along with the data, so it may be easier to understand the difference between my plot code and yours!

sorry the code came out funky
figure(2)
names = 1:1:rx;
for i =1:1:rx
name = i;
plot (fx,fy,'bo',ax(i,1),ay(i,1),'bo',ax(i,2),ay(i,2),'bo')
xlim([0 50]);
ylim([0 50]);
title(sprintf('%s Step: %i',sys,i));
pause (0.35)
end
