Graphs not plotting correctly.

First of all, I went ahead and reworked the messy goto-crap (or I am trying at least right now).
However, now that I am working on those, I get two problems, both of them I have no clue why they even happen.
Right now, when I plot all graphs using the new functions, as long as I don't define an axis before the function actually plots them, the graphs are cut short randomly and at different points:First of all, I went ahead and reworked the messy goto-crap (or I am trying at least right now).

Right now, when I plot all graphs using the new functions, as long as I don't define an axis before the function actually plots them, the graphs are cut short randomly and at different points:
This would also happen if I define my axis before the plot of the graph function. It just won't be noticeable until I move the plot around.
Why do these graphs not go all the way? And why do they stop at different points?
As I understand it, the axis limits don't result in the graphs being plotted differently. And, as I remember from other codes I've written, that's not the case.
Also, am I right to assume that I should open a new question every time, instead of asking as follow-ups on my first one?
Thank you
ttest is the file with the normal script.
%%% Normal Script
%% First section is just vector definition
InputCheckFinished=1;
for InputCheck=1:1:InputCheckFinished;
answer = inputdlg('How many X are plotted?:',...
'Sample', [1 50]);
NofRepeatsX= str2double(answer{1});
answer = inputdlg('How many Y are plotted?:',...
'Sample', [1 50]);
NofRepeatsY= str2double(answer{1});
end
for j=1:1:NofRepeatsX
answer = inputdlg('Enter x-Vector with spaces line by line, 1 iteration=1 vector later on:',...
'Sample', [1 100]);
x_Vector= str2num(answer{1});
matx(j,:)=x_Vector
j=j+1;
end
for j=1:1:NofRepeatsY
answer = inputdlg('Enter y-Vector with spaces line by line, 1 iteration=1 vector later on:',...
'Sample', [1 100]);
y_Vector= str2num(answer{1});
maty(j,:)=y_Vector
j=j+1;
end
clear answer
%% second section is calling the fit and plot functions/defining axis
close all
[NumRows,NumCols]=size(maty);
clear NumCols
hold on
fits=LPfitfun(matx,maty,NumRows)
hold on
axis([-10 10 -10 10])
plotfunction_beta
axis([-10 10 -10 10])
%hold on
%% third section: the fit function (not the same script as section 1/2)
function [fits] = LPfitfun(matx,maty,NumRows)
%LPfitfun Summary of this function goes here
% compute a LPfit for inputs matx,maty,fittype poly1
for k=1:1:NumRows
hold on
fits{k}=fit(matx(k,:)',maty(k,:)','poly1')
hold on
end
end
%% fourth section: the plot function that is not a function. I cant get the actual function to work (see last section) (not the same script as section 1/2)
fits=LPfitfun(matx,maty,NumRows) %fits is the name of the cell in which all fits are stored. the string
%LPfitfun(matx,maty,Numrows) takes these
hold on
for k=1:1:NumRows
hold on
axis()
plot(fits{1,k},'')
hold on
plot(matx(k,:),maty(k,:),'o')
hold on
end
disp('DONEBeta')
%% fifth section: the actual plot function that is not working
function[LPplotfun]=LPplotfun(matx,maty,fits,NumRows)
%LPplotfun plots all LPfitset up by LPfitfun
hold on
for k=1:1:NumRows
hold on
plot(fits(1,1),'')
hold on
plot(matx(k,:),maty(k,:),'o')
hold on
pause(3)
hold off
end
hold on
disp('Doneplotfun')
end
%% Error message when trying to plot using LPplotfun:
Not enough input arguments.
Error in LPplotfun (line 4)
for k=1:1:NumRows
Error in ttest (line 190)
LPplotfun
% I know this is a bit of a problem- and code-dump. I am not seeing the problem right now.

Hello,
How are calling LPplotfun ?
Seems like NumRows is not defined or passed into LPplotfun.

Replace you plotfunction_beta with your function:
LPplotfun(matx,maty,fits,NumRows)
Also, I never have returned the name of a function in function return like that. It is okay if your function is defined as:
function LPplotfun(matx,maty,fits,NumRows)
end
or
function[]=LPplotfun(matx,maty,fits,NumRows)
