legend properties of columnlegend

Hi :)
I would like to use columnlegend to make my legend appear nicely. Since I need to change the fontsize and -weight, I used the following code:
h = columnlegend(2, p2, 'location', 'southoutside');
h.FontSize = 16;
h.FontWeight = 'bold'
h
where p2 contains the strings for the legend.
when I look at the properties of h, they changed to the desired values, but they do not change in the plot.
The same happens, when I enter it directly to the legend command:
h = columnlegend(2, p2, 'location', 'southoutside','FontSize',16,'FontWeight','bold');
The image shows my problem. I am using R2016b.
Does someone know how to solve this?

The problem
The file exchange function columnlegend() (started in 04/2010, last updated 09/2016) calls legend() with multiple outputs,
[legend_h,object_h,plot_h,text_strings] = legend(str);
Note: This syntax is not recommended and creates a legend that does not support
all graphics features. Use the l = legend(__) syntax to return the legend object
and set Legend Properties instead.
Toward the top of Matlab's legend code, a flag named version is set to on when the number of output arguments is greater than one. When version is on, a legacy version of the legend is created by this function which we do not have access to
leg.doPostSetup(version_flag);
Solution
Starting in r2018a, you can set the NumColumns property of Matlab's legend() function making the columnlegend() function obsolete (thanks to the original author, Simon Henin, for inspiring that change in Matlab).
legend(. . ., 'NumColumns', 2)
For Matlab releases prior to r2018a, use the 2nd output of columnlegend(), isolate the legend string handles, and change the text properties.
[h, object_h] = columnlegend(. . .);
% Set spacing (This will not change font size or weight)
set(h, 'FontSize', 16, 'FontWeight', 'bold')
% Get text handles
legTextHand = object_h(strcmpi(get(object_h,'type'),'text'));
% Change fontsize and weight
set(legTextHand,'FontSize',16,'FontWeight','bold')

Ah.... this section below sets the spacing
h.FontSize = 16;
h.FontWeight = 'bold'
while this section below sets the fontsize etc.
set(legTextHand,'FontSize',16,'FontWeight','bold')
Glad I could help.
