zoomed plot in the same figure

Hello i am trying to do a zoomed plot in the same figure using the plotyy function... Ive tried to play around with the explanations given here https://de.mathworks.com/matlabcentral/answers/33779-zooming-a-portion-of-figure-in-a-figure but i couldnt make it so far... The section im interested in is between the graphs plotted by (x5,y5,x6,y6) at x between 0.6 and 0.8 and y between 0.18 and 0.2.... If someboy could give me a hint i would be really greatfull. The version im using is R2012a..

Thank you very much

%Bed profile of Run 20°C 
BP_num_6s_fv=xlsread('Results.xlsx','t=6s',' M3:N203');

%Velocities of Run 20°C and Run 5°C
velo6s_20=xlsread('Results.xlsx','Velocity',' I3:J203');
velo6s_5=xlsread('Results.xlsx','Velocity',' L3:M203');

% Bed profile At t=6s
 x1 = BP_num_6s_fv(:,1);            y1=  BP_num_6s_fv(:,2);

   % Velocity Run 20°C and 5°C
   x5 = velo6s_20(:,1);          y5 =velo6s_20(:,2);
    x6 = velo6s_5(:,1);          y6 =velo6s_5(:,2);

   figure (1)

hold on

   [ax,h1,h2]=plotyy(x1,y1,x5,y5)
   h(3) = line(x6,y6, 'Parent', ax(2));
  set(h(3),'Color','r')

% create a new pair of axes inside current figure
axes('position',[.65 .175 .25 .25])
box on % put box around new pair of axes

indexOfInterest = (x5 < 0.8) & (x5 >0.6); % range of t near perturbation
a=x5;
plot(a(indexOfInterest),g(indexOfInterest)) % plot on new axes
axis tight

And what does this code actually give you, what aspect of it is incorrect?

[christian robledo]

actually it doesnt give me any output.. im not able to specify correctly the x and y sections that i want to plot as zoomed figure..

[Adam]

Would it not just be easier to set the XLim and YLim properties to the desired range?

[christian robledo]

maybe.. im just kind of starting with matlab and struggling with the basics.. could you maybe show me how i can implement it in my code? that would be awesome!

Ive tried someting like this but it just gives me like a straight line

figure (1)

hold on

   [ax,h1,h2]=plotyy(x1,y1,x5,y5)
   h(3) = line(x6,y6, 'Parent', ax(2));
  set(h(3),'Color','r')
  % create a new pair of axes inside current figure
  axes('position',[.65 .175 .25 .25])
  box on % put box around new pair of axes
  indexOfInterest1 = (x5 < 0.8) & (x5 >0.6); % range of t near perturbation
  indexOfInterest2 = (y6<0.2) & (y6>0.18);
  plot(indexOfInterest1,indexOfInterest2 )

axis tight

Do you mean:

indexOfInterest = (x5 < 0.8) & (x5 >0.6); % range of t near perturbation
plot(x5(indexOfInterest), y6(indexOfInterest));

There are some zoom tools in the FileExchaage:

Hello Jan yes thanks, i think now it plots the right section.. the only thing is that it only plots one graph... In the figure were i denoted area of interest there are actually two graphs very very close to each other (x5,y5 and x6,y6).. thats why i wanted to have that zoom in plot... is there a way to make them both visible? Thanks again for your answer

[Jan]

If you know the code to plot one line, use it to draw both lines:

axes('position',[.65 .175 .25 .25], 'NextPlot', 'add')
indexOfInterest1 = (x5 < 0.8) & (x5 > 0.6);
indexOfInterest2 = (x6 < 0.8) & (x6 > 0.6);
plot(x5(indexOfInterest1), y5(indexOfInterest1));
plot(x6(indexOfInterest2), y6(indexOfInterest2));
