Creating and closing figure takes a really long time

15 views (last 30 days)
Hello
I have a simple class which creates an uifigure with a grid, a couple of panels and multiple axes:
classdef multiChanFig < handle
properties
f
panelU
axesU = gobjects(2,0);
panelT
axesT = gobjects(0);
shownCh = [];
titles = [];
end
methods
function obj = multiChanFig(shownCh)
obj.f = uifigure('Position',[50,50,1800,900]);
g = uigridlayout(obj.f);
g.RowHeight = repmat({'1x'},[1,2+length(shownCh)]);
g.ColumnWidth = repmat({'1x'},[1,length(shownCh)]);
g.ColumnSpacing = 0;
g.RowSpacing = 0;
g.Padding = [0 0 0 0];
for ii = 1:length(shownCh)
for jj = 1:2
np = uipanel(g);
np.BorderType = 'none';
np.Layout.Row = jj;
np.Layout.Column = ii;
obj.panelU(jj,ii) = np;
obj.axesU(jj,ii) = axes('Parent',obj.panelU(jj,ii));
end
np = uipanel(g);
np.BorderType = 'none';
np.Layout.Row = 2+ii;
if length(shownCh) == 1
np.Layout.Column = 1;
else
np.Layout.Column = [1, length(shownCh)];
end
obj.panelT(ii) = np;
obj.axesT = axes('Parent',obj.panelT(ii));
end
end
end
end
I am calling it from command line using:
o = multiChanFig([1,2,3])
It takes so long to "create" (the actual popup is pretty quick but then the axes limits/ticks auto-adjusting to the size of the window takes a looong time) and when I click on the X to exit the figure it takes 20+ seconds are you can see from this profiler:
Vast majority of the slowdown comes from Matlab figure processes it seems, with the biggest offenders being ControlManager.sendControlManagerMessage and InteractionsManager.sendInteractionsManagerMessage. These are both P-files so I cannot even see why it takes so long to do such simple operations.
Has anyone else encountered this? Any advice? Thanks
