How do I right or left justify text in my plot?
The Handle Graphics property 'HorizontalAlignment' does not right justify the text in my title as I expected. I want my title to appear on the top right-hand side of my figure.

The ability to present a legend in the form of a matrix is added in MATLAB 9.4(R2018a).
You can specify Number of columns by using NumColums property of Legend object.
For details, please refer the documentation.
In R2017b and previous release, it is not available as a built-in feature of MATLAB.
However, there exist several workarounds:
1) Use the GRIDLEGEND function from MATLAB Central:
2) Use the COLUMNLEGEND function from MATLAB Central:
3) Use the FLEXLEGEND function from MATLAB Central:
4) Use the following code:
% Example data
xData = linspace(0,pi);y1 = sin(xData);y2 = cos(xData);y3 = sin(xData.^2);y4 = cos(xData.^2);% Plot the first two sets of data
ph1(1) = plot(xData,y3,'-ko','DisplayName','Y3 Legend Text');hold onph1(2) = plot(xData,y4,'-bs','DisplayName','Y4 Legend Text');% Create the first legend
lh1 = legend(ph1,'Location','NorthOutside','Orientation','horizontal');lh1_position = get(lh1,'Position');% Now set any axis properties that you want (Font, Ticks, etc)
fontSize = 16;xlimits = [0,pi];ylimits = [-1, 1];xticks = [0, pi/2, pi];yticks = [-1, 0, 1];xTickLabels = {'0', 'pi/2', 'pi'};set(gca,'XLim',xlimits,'YLim',ylimits,'FontSize',fontSize,'XTick',xticks,'YTick',yticks,'xTickLabel',xTickLabels);% Name the first axis ax1 and create a second axis on top of the first
ax1 = gca;ax2 = axes('Position',get(ax1,'Position'));% Plot the second two sets of data on ax2
ph2(1) = plot(xData,y1,'-rd','DisplayName','Y1 Legend Text','Parent',ax2);hold onph2(2) = plot(xData,y2,'-g^','DisplayName','Y2 Legend Text','Parent',ax2);% Again set any axis properties that you want (Font, Ticks, etc) to make sure that the Legend fonts are the same
set(ax2,'XLim',xlimits,'YLim',ylimits,'FontSize',fontSize,'XTick',xticks,'YTick',yticks);% Now, link the first axis to the second and make the second invisible
linkaxes([ax1 ax2],'xy');set(ax2,'Color','none','XTick',[],'YTick',[],'Box','off');% Now make the second legend just above the first
lh2 = legend(ax2,ph2,'Orientation','horizontal');lh2_position = lh1_position;lh2_position(2) = lh1_position(2)+1.25*lh2_position(4);set(lh2,'Position',lh2_position);Moving the R-axis with 'polarplot' The 'polarplot' function was introduced in MATLAB R2016a as a replacement for the 'polar' function, which makes it easier to customize polar plots.
See the documentation linked below, which outlines the properties of 'polaraxes' for more information:
The 'RAxisLocation' property can be used to set the location of the R-axis labels in degrees:
% Create a polar plot.
pp = polarplot(sin(0:0.01:10*pi));% Get a handle to the polar plot axes.
ax = gca;% Set the location of the R-axis labels in degrees.
degrees = 300;ax.RAxisLocation = degrees;If you are unable to use the 'polarplot' function, you can follow the workarounds below to hide or move the R-axis labels using the 'polar' function.
Hiding the R-axis with 'polar' 1.) To hide the R-axis labels, first locate all of the 'Text' objects in the graphics object hierarchy using the 'findall' command. Then, filter the results using the 'HorizontalAlignment' property of the 'Text' objects.
PLEASE NOTE: This filtering method relies on the default value being set to 'left' for the 'HorizontalAlignment' property of the 'Text' objects created by the 'polar' command.
% Taken from 'doc polar' example:
% http://www.mathworks.com/help/matlab/ref/polar.html
theta = 0:0.01:2*pi;rho = sin(2*theta).*cos(2*theta);f = figure;polar(theta,rho,'--r');% Extract all of the 'Text' objects from the polar plot.
ax = findall(f.Children, 'Type', 'Axes');% Filter the 'Text' objects by the 'HorizontalAlignment' property.
% PLEASE NOTE: This may not generalize to other versions of MATLAB
% where the default 'HorizontalAlignment' value for R-axis labels is not
% set to 'left'.
labels = findall(ax, 'Type', 'Text', 'HorizontalAlignment', 'left');% Hide all the R-axis labels.
[labels.Visible] = deal('off');Moving the R-Axis with 'polar' 2.) To move the R-axis labels, first locate the corresponding 'Text' objects in the graphics object hierarchy, as described above. Then, iterate over the appropriate set of 'Text' objects, and update the 'Position' property of each object.
The code below provides a simple method of setting the 'Position' property of each 'Text' object in degrees on the polar plot. You can modify the value of the 'degrees' variable to choose where you want to place the R-axis labels on the polar plot.
% Taken from 'doc polar' example:% http://www.mathworks.com/help/matlab/ref/polar.htmltheta = 0:0.01:2*pi;rho = sin(2*theta).*cos(2*theta);f = figure;polar(theta,rho,'--r');% Extract all of the 'Text' objects from the polar plot.ax = findall(f.Children, 'Type', 'Axes');% Filter the 'Text' objects by the 'HorizontalAlignment' property.% PLEASE NOTE: This may not generalize to other versions of MATLAB% where the default 'HorizontalAlignment' value for R-axis labels is not% set to 'left'.labels = findall(ax, 'Type', 'Text', 'HorizontalAlignment', 'left');% Set the degrees of the R-axis Labels.
degrees = 300;% Update the position of each R-axis label.
for label = labels' currentX = label.Position(1); currentY = label.Position(2); radius = sqrt(currentX^2 + currentY^2); newX = cos(degtorad(degrees)) * radius; newY = sin(degtorad(degrees)) * radius; label.Position = [newX, newY];endRelated Question
