I have a code that generates a uifigure. Then it populates this figure with graphs, table and a map. I then run a function and it populates these figures, graphs map etc.
I want to create some code to check if the figures, graphs map etc. have been populated and if so clear then to run other functions, without having to reset up the ui figure

Hi Katherine,
I understand that you're interested in verifying whether a uifigure is populated or not and, if so, you'd like to remove the graphs for subsequent functions. To accomplish this, you can make use of the "Children" property of the uifigure. Please refer to the example below, which checks for the presence of a graph on the uifigure:
% Create a uifigure
fig = uifigure;
% Populate a graph onto the figure
ax = uiaxes(fig);
x = 0:0.01:2*pi;
% Check for the Children
% You can put a check on the length for the if condition
% Clear / remove the Children
% Check for the Children
If you are specifically interested in checking whether the graph is populated or not, you can examine the "Children" property of the axes as well:
Hope this information helps you address the issue.
