Can't seem to get the functions to graph properlly
You've chosen a pretty coarse resolution for t. If you change it to something like t = linspace(0,5,100); do you get what yo...

Diagonal Node Labels for Bipartite Graph?? (Undirected Graph Formatting Help)
The node labels in a plotted graph are difficult to alter. You can get to them by digging into undocumented properties. For ex...

i have a syntax error in u(3)-u(4)(​exp((u(2)u​(1)+u(6)))​)/(u(5))-1​) what the error ?
A few missing multiplication symbols: u(2)*u(1) and u(4)*(exp...)

Specify location of clabel
I've used the FEX function gclabel in the past to do this sort of thing, though I haven't tested it in any recent versions of Ma...

Extracting Numbers from a mixed string
Assuming numbers only appear as properly-formatted combos, you can simply look for all number-decimal groups: b = regexp(str, '...

Adjusting my time axis(x axis) accordingly
t = (0:(n-1))*(1/fs); plot(t,y1)

plotting 2gb worth of data
You're trying to show about 10x more data than could possibly be visualized, even on a 4K monitor. Even if you didn't run out o...

How to make a circular graph (node connections)?
The short answer is that you can indeed make these in Matlab, but it's not simple. You basically need to recreate the calcula...

Daily average of several years data
You might also take a look at reshapetimeseries.m (part of the Climate Data Toolbox). Setting the 'bin' option to 'date' will r...

error bars continue at other border of figure
I think the easiest way to do this would just be to plot the data, plus the data shifted one modulo to each side; the replicates...

Plot curve becomes jagged after 1000 data points (seems to plot one point and stretch it the length of 10)
It's difficult to say without actually seeing the underlying data... but at first glance this looks like a change in precision i...

Heat (or color coded Map) in Matlab
In my opinion, the easiest way to do this is to alter the colors of the patches after plotting with mapshow/geoshow. An example...

Can the vertical exaggeration of geographic axes be reduced so plots don't warp as much as they do now?
If you don't have the Mapping Toolbox, I recommend using m_map. Basically, you're asking to reinvent map projections, and that'...

What happened to the ESRI file in the mapping toolbox projection files in 2020b PR?
I'm not sure if this will work for your use case, but I wrote my shapeprjread function to parse certain projected shapefiles. I...

boundedline.m
Plot one or more lines with a shaded boundary (can represent error, confidence intervals, etc).

Colour plot vs Time on a circle
It's not clear to me whether you've already created the circle plots in Matlab, or if you just sketched out your desire outcome....

Contourf is plotting weird lines. How to remove them?
When you let contour choose contour levels automatically, it doesn't always choose the levels you really want. In this case, it...

Is it possible to bring "grid on" to the front of a figure?
By default, all plotted objects are rendered on top of the axis (including axis lines, grid lines, etc). You can reverse that b...
