MATLAB: Changing axes linewidth on a stacked plot

axeslinewidthMATLABstackedplot

I cannot change the axes linewidth on a stacked plot, at least in the way that I am able to change the axes linewidth in other types of plots. For example, I have tried the following with no change to the axes linewidth:

figure(1)
stackedplot(time_axis, testdata)
hAx=gca;    
hAx.LineWidth=2;

You have to access the axis handles first.

h = stackedplot(rand(10,4)); 
ax = findobj(h.NodeChildren, 'Type','Axes'); % use flipud to puts axes in order. 
set(ax,'LineWidth',2)

"How do I cange the Xticklabels of a plot using figure handles?"

Get the axis handle from the figure handle.

ax = gca(figureHandle);

Get the XAxis handle from the axis handle and set the FontSize of the x-axis only.

ax.XAxis.FontSize = 16;

or set the fontsize of the entire axis (x & y)

ax.FontSize = 14;

Set the XTick and XTick labels

ax.XTick = 1:4; 
ax.XTickLabel = {'A' 'B' 'C' 'D'};

MATLAB: How to change the linewidth of the axes without affecting the linewidth of the legend box

Use the two object handles to set their respective properties--although legend does inherit axes properties such as the linewidth from its parent axis which makes a certain amount of sense.

hAx=gca;                    % create an axes
hL=plot(randn(5,1));        % and a line underneath
hAx.LineWidth=2;            % set the axis linewidth for box/ticks
hLg=legend('A');            % put a legend on the figure
hLg.LineWidth=1;            % make the legend axes box linewidth smaller

Presuming hobj is the handle of the figure or returned by whichever function used to plot in the axes, hl above is the line in the graph equivalent to hL above. Setting 'LineWidth' for that object changes the linestyle of the line itself, not the same property at all as the axes. And, changing it will change the line characteristics in both as the legend reflects the characteristics of the associated line in the axes to which it belongs. That is a builtin connection that is immutable without trickery to create secondary lines such that the connection between which legend entry is shown and the given line is disguised by creating hidden objects or similar.
