How to set the origin to the center of the axes in Matlab

Question

When I draw the f (x) function in Matlab, for example, a sinusoidal function, I get the following:

I want to build it differently, for example using Mathematica:

Pay attention to the position of the axes (together with ticks) and the position of the x and y labels.

Any help would be greatly appreciated.

Answer 1

Because not all readers have the latest version of MATLAB, I decided to make this answer a little more general, so now it is a function that receives a shape for manipulation as an input pointer and sets its beginning in the center:

function AxesOrigin(figureh)
% set the origin of a 2-D plot to the center of the axes

figureh.Color = [1 1 1];
% get the original properties:
del_props =  {'Clipping','AlignVertexCenters','UIContextMenu','BusyAction',...
    'BeingDeleted','Interruptible','CreateFcn','DeleteFcn','ButtonDownFcn',...
    'Type','Tag','Selected','SelectionHighlight','HitTest','PickableParts',...
    'Annotation','Children','Parent','Visible','HandleVisibility','XDataMode',...
    'XDataSource','YDataSource','ZData','ZDataSource'};
lineprop = figureh.CurrentAxes.Children.get;
lineprop = rmfield(lineprop,del_props);

x = lineprop.XData;
y = lineprop.YData;
old_XTick = figureh.CurrentAxes.XTick;
old_YTick = figureh.CurrentAxes.YTick;
old_Xlim = figureh.CurrentAxes.XLim;
old_Ylim = figureh.CurrentAxes.YLim;

% check that the origin in within the data points
assert(min(x)<0 && max(x)>0 && min(y)<0 && max(y)>0,'The data do not cross the origin')

figureh.CurrentAxes.Children.delete
axis off

% Create Q1 axes
axes('Parent',figureh,...
    'Position',[0.5 0.5 0.4 0.4],...
    'XTick',old_XTick(old_XTick>0),...
    'YTick',old_YTick(old_YTick>0));
xlim([0 max(old_XTick)]);
ylim([0 max(old_YTick)]);

% Create Q3 axes
axes1 = axes('Parent',figureh,...
    'YAxisLocation','right',...
    'XAxisLocation','top',...
    'Position',[0.1 0.1 0.4 0.4],...
    'XTick',old_XTick(old_XTick<0),...
    'YTick',old_YTick(old_YTick<0));
xlim(axes1,[min(old_XTick) 0]);
ylim(axes1,[min(old_YTick) 0]);

% Create real axes
axes2 = axes('Parent',figureh,...
    'Position',[0.1 0.1 0.8 0.8]);
hold(axes2,'on');
axis off

plot(x,y,'Parent',axes2)
set(axes2.Children,lineprop)
xlim(axes2,old_Xlim);
ylim(axes2,old_Ylim);
end

Answer 2

MATLAB 2015b ( ) 'origin' XAxisLocation YAxisLocation . :

ax = gca;                        % gets the current axes
ax.XAxisLocation = 'origin';     % sets them to zero
ax.YAxisLocation = 'origin';     % sets them to zero
ax.Box = 'off';                  % switches off the surrounding box
ax.XTick = [-3 -2 -1 0 1 2 3];   % sets the tick marks
ax.YTick = [-1 -0.5 0 0.5 1];    % sets the tick marks

Answer 3

:

ha = gca;
ha.XAxisLocation = 'origin';
ha.YAxisLocation = 'origin';
