some plots not showing in plot pane (while others do show)
i'm having trouble getting some plotting functions to work, while others work fine. here's an example. the first plot (with plot() function) works fine. the second plot with diagrammer mermaid() function doesn't work. the plot pane goes blank, and for some reason the 'viewer' pane becomes the active…
at this point i would uninstall rstudio and reinstall it.
hi,

do you have joy package installed with all necessary packages/dependencies ?

try to search for joy\_node or run joy package examples to find out what is going wrong. can you try with other dropdowns? if its working , nothing wrong with your code and something to do with that specific drop down. if you do not need the "wave" contents for a further use, just drop out (k) from all its entries.
if you need it for a further use, initialize it as 
wave=zeros(3,numel(t));
before the loop and address it as wave(k,:) within the loop.
commands "stem" are definitely incorrect. if you want to see plots of the dependences on t, they should look something like stem(t,combined) or plot(t,combined), etc. however, the t range in the second version (0,3) is much wider than the one of the first version (0,0.01): consequently, such a graph will show much (hugely) more oscillations--you will probably see nothing but a unifromly painted square.
i do not see any need in the "nold on" and "hold off" commands in the both version. Shawn,
 
If no brighter suggestions appear, you may try the list:
 
 
 
THE LIST
 
 
If things that should work simply refuse to (all possibilities exhausted including the A) - D) below (and carefully making sure you are performing (all) the needed things)), you may try (the relevant part(s) of) the list 1) - 8 ) below.
 
 
Sometimes, (certain) things may fail or stop working for no apparent reason. When the (other) possible reasons/cures fail to work, it may be some kind of (temporay or permane... hi,

i think the problem is the dynamo version you’re using.

now i have the most complex geometry (dynamo vers. 2,3,0) without problems.

if possible, can you send us an example to test?

here’s an example:

[[1]](https://aws1.discourse-cdn.com/business6/uploads/dynamobim/original/3x/a/b/abcdb448d6e4193cee39105fb567675cbb19a9be.png "1")

durmus check out the intersect function.
here is one approach:
% generate a rectangular boundry
rectx = [0.1 0.1 0.9 0.9];
recty = [0.1 0.5 0.5 0.1];
rect = polyshape(rectx,recty);

% initialize a figure for display purposes
figure(1);clf
titles = [...
 "all lines";...
 "partially within";...
 "exclusively within"];
for i = 1:3
 subplot(1,3,i)
 hold on
 title(titles(i))
 plot(rect)
 xlim([0 1])
 ylim([0 1])
end

% define the number of line segments to generate
nlines = 25;

% initialize a structure to store the lines (if you need the data later)
lines = struct();

% generate each line, calculate it's intersection conditions, and plot
for i=1:nlines
 
 % generate points for a random line segment
 lines(i).points = rand(2);
 
 % section the line into parts at intersection with the rectangle
 [in, out] = intersect(rect, lines(i).points);
 
 % plot all the lines that were generated
 subplot(1,3,1)
 line(lines(i).points(:,1),lines(i).points(:,2))
 
 % plot lines that are partially within the boundary
 if isempty(in)==0
 subplot(1,3,2)
 line(lines(i).points(:,1),lines(i).points(:,2))
 end
 
 % plot lines that are exclusively within the boundary
 if isempty(out)==1
 subplot(1,3,3)
 line(lines(i).points(:,1),lines(i).points(:,2))
 end
end
here is the output: hi@thebatswhiskersjust checking in on your half hourly usage issue?i think you’re also effected by the situation outlined in this topic, where i confirm:please be advised that there is a known issue effecting some customers, where half hourly usage information is not populating ontoonline usage graphs, despite good smart meter comms, and a populated monthly chart.if you haven’t already, we’d appreciated it if you could make oursupport teamaware of this, so a ‘case’ can be raised, helping us to identify the volumes of those effected. hi, 
this is really strange behavior. the only option i see is atm to reset your preferences and check if it works again, then. 
options- > preferences -> reset preferences (left corner) 
hope that helps. 
regards 
christoph because each time fill() is invoked it is only applying 0.047% opacity over what was previously drawn. draw() runs aprox 60 times per second … hi tomica, - - i can suggest that you try the following: -     - remove all of the styles to see whether some specific css is affecting the buttons appearance. -     - upgrade to latest telerik ui version - 2015.2.826 - if the above steps, however, do not help it would be better to provide us with a runnable sample that reproduces the issue, so that we can investigate it further. - - regards, - danail vasilev - telerik - - do you want to have your say when we set our development plans? - do you want to know when a feature you care about is added or when a bug fixed? - explore the - telerik feedback portal - and vote to affect the priority of the items -
