When I plot it comes with both axes in the box. How can I plot by removing right axis (or vertical line) of Box? can you please help me?
x=(1:1:10);
y= (1:2:20);
figure (1);
plot (x,y,'o-');

x = (1:1:10);
y = (1:2:20);
figure (1);
plot (x,y,'o-');
ax = gca;
ax.Box = 'off';
I don't think it's possible to remove just the right box border.
One thing you can do is move the border away from the plot by setting XLim. If your goal is just to create space for annotations to add to the plot, this might work:
x = (1:1:10);
y = (1:2:20);
figure (1);
plot (x,y,'o-');
ax = gca;
ax.XLim = [1 15];

yes you are right I want to add another plot by removing the right boarder. Can please give me the more idea about it how can get the plot like this as attched below? thank you

Turn off right-y-axis
This solution is similar to another answer provided a few days ago. It uses yyaxis to add a second, independent y-axis on the right and then turns the color off for that axis.
x=(1:1:10);
y= (1:2:20);
figure (1);
plot (x,y,'o-');
yyaxis right
ax = gca();
ax.YAxis(2).Color = 'none';
yyaxis left % return focus to 'main' axis.
Join 2 axes, control the center border line
Update following an example added by OP
This version joins 2 axes, turns off the y-axes in the center of the two axes, formats the left-y-axis of the right-axes as a dashed line, and then links the two sets of y-axes so they always have the same y-limit.
The juxtaposition of the axes uses TiledLayout with zero-tile-spacing which requires Matlab r2021a (see Community Highlight). For versions of Matlab prior to R2021a, create the two axes using the axes command and set their position properties (see version-2 below).
x = 0:0.1:10;
y = gaussmf(x,[2 5]);
figure()
tiledlayout(1,2,'TileSpacing','none'); % Requires Matlab r2021a or later
ax1 = nexttile();
plot(ax1, x,y)
yyaxis(ax1,'right')
ax1.YAxis(2).Color = 'none';
yyaxis(ax1,'left') % return focus to 'main' axis.
xlabel('Left Axis')
ax2 = nexttile();
plot(ax2, x,y)
yyaxis(ax2,'right')
ax2.YAxis(2).Color = ax1.YAxis(1).Color;
ax2.YAxis(2).TickLabels = []; % Turn off right tick labels
yyaxis(ax2,'left') % return focus to 'main' axis.
ax2.YAxis(1).TickValues = [];
ax2.YAxis(1).Axle.LineStyle = 'dashed';
linkaxes([ax1,ax2],'y') % link both sets of y-axis limits
xlabel('Right Axis')
Version-2 using custom axes instead of TiledLayout
x = 0:0.1:10;
y = gaussmf(x,[2 5]);
figure()
margins = [.13 .11 .25]; % [left&right, bottom, top], normalized units
ax1 = axes('Units','Normalize','Position',[margins(1:2),.5-margins(1),1-margins(3)]);
plot(ax1, x,y)
yyaxis(ax1,'right')
ax1.YAxis(2).Color = 'none';
yyaxis(ax1,'left') % return focus to 'main' axis.
xlabel('Left Axis')
ax2 = axes('Units','Normalize','Position',[.5,margins(2),.5-margins(1),1-margins(3)]);
plot(ax2, x,y)
yyaxis(ax2,'right')
ax2.YAxis(2).Color = ax1.YAxis(1).Color;
ax2.YAxis(2).TickLabels = []; % Turn off right tick labels
yyaxis(ax2,'left') % return focus to 'main' axis.
ax2.YAxis(1).TickValues = [];
ax2.YAxis(1).Axle.LineStyle = 'dashed';
linkaxes([ax1,ax2],'y') % link both sets of y-axis limits
xlabel('Right Axis')
Additional recommendations
  • Set the x-ticks to avoid the overlap at the x-limits.
  • Turn the grid on for both pairs of axes (yyaxis left)

Thank yo But it didnt help as I am using 2019a version of martlab. For example I tries this one. It gave me blank!!! Can you make left axis off for the following example. I am so sorry
x1=(1:1:10);
y1= (1:2:20);
x2=[1,2,3,4,5];
y2=[0.1,3,6,7,2];
figure (1);
ax1 = axes('Position',[100 100 600 500]);
h1=plot (ax1,x1,y1,'r-'); hold on;
h2=plot (ax1,x2,y2,'k-'); hold off
set(h1 ,'LineWidth',2.5);
set(h2 ,'LineWidth',2.5);
yyaxis(ax1,'right')
ax1.YAxis(2).Color = 'none';
yyaxis(ax1,'left') % return focus to 'main' axis.
xlabel('Left Axis')
set(gca,'FontSize',18)
set(gcf,'Position',[100 100 600 500])

The reason you have a blank figure is because your axes size is 600x500 but axis units are normalized by default so the largest size is 1x1.
I'll update my answer with a demo using custom axes.
