in LaTeX, it would be something like
\overset{\circ}{K}
which will result in the letter K with a circle above it in the center (not on the right as a superscript). However, my question is, how can I do the same in MATLAB text, e.g. in figures' titles or labels?
Is this close enough?
figure(); title('$\mathop K\limits^ \circ$','interpreter','latex');

I have some data with a long tail, which has been truncated for a histogram. I would like to add a simple "+" sign to the final value of the x-axis on the histogram. Below is an example showing the setup.
sysuse auto
gen price_graph = price
replace price_graph =10000 if price_graph>10000
hist price_graph, start(0) width(1000)
Below is the result of the above code, with the "+" sign drawn in and highlighted where I would like to put it:
I could also see scenarios when data would be truncated from the left as well, so a robust solution would be easily applicable to both scenarios.
hist price_graph, start(0) width(1000) xla(0(2000)8000 10000 "10000+")
You spell out that you want specific text as a specific axis label. You then (optionally) indicate what other labels you want.
I'm printing an adhesive label (6x5cm) with a printer model 3nStar RPT006.
In the adhesive I am printing a title, QR code and the QR code in text
something like this
My Title
▄
qr code
Using this class as reference, I'm doing something like this:
initialize(),
setJustification(Printer.JUSTIFY_CENTER),
'My Title',
feed(),
qr(qrText),
feed(),
qrText,
feed(2),
cut(Printer.CUT_FULL, 1),
My problem is: I don't know how to control the vertical size, or how to set the height of the paper. Between each label I have a gap of 3mm.
So my question is, how should I handle the vertical spacing/height?
Currently I very close to get a perfect label, but seems like the printed label is some millimeters shorter and each time I print a label, it miss a little bit more, so there is a time where I start to cut the adhesive part and not the gap
I'm not sure if it's possible in your environment, but there are three options.
Prepare blank image data with the required number of vertical dots and print it(graphics(EscposImage $image, $size)) instead of the line feed code.
Use setLineSpacing($height) to change the height of one line only for the required part and start a new line. Then return to the original size.
Make your own customization by adding the function to feed the paper in dot units to the library for printing.

I have a slide with some hand-drawn circles on it. I'd like to get a list of the coordinates and radii (sizes) of them. Attached is an image and link. Anyone have an idea how?
I started looking into computer vision techniques, but it seems like there should be a much more direct way.
If you are familiar with openCV the method HoughCircles() will do the job:
http://docs.opencv.org/doc/tutorials/imgproc/imgtrans/hough_circle/hough_circle.html
Are you familiar with Matlab? imfindcircles() will do it:
http://www.mathworks.com/help/images/ref/imfindcircles.html
If this is a one time job you can post it as a job for someone else to do it for you for a small fee. Example: https://www.mturk.com/mturk/welcome
If you don't know any programming language and this is a one time job, you can do it manually. You can select each circle in photoshop, count the amount of pixels (and using the formulae of circumference = 2*pi*radius) find the radius. The center of mass of all the pixels will be the center of the circle.
It is a bit tricky to separate overlapping circles but you can do it by hand
I found a suitable method using vector graphics.
Select all the circles in powerpoint, right click and 'save as a picture'. Use .emf (windows metafile) format (this option was only available on my windows machine, not mac).
Open the emf file in inkscape, and save it to an 'svg' format, which is ascii and human readable.
Extract the information from the path commands.
E.g.: Each circle is represented as a path object, with a line:
d="m 36.527169,36.434607 c 0,-9.696733 9.075703,-17.551993 20.274845,-17.551993 11.194626,0 20.270329,7.85526 20.270329,17.551993 0,9.69264 -9.075703,17.552246 -20.270329,17.552246 -11.199142,0 -20.274845,-7.859606 -20.274845,-17.552246"
Here, the (x,y) following the 'm' character is the center of the circle, and the 12 (x,y) pairs following 'c' denote a 4-segment polybezier curve in which pairs 3,6,9,12 are the four compass points. Therefore in the above object, this is not a circle but an ellipse with axes ~ 20.27 and 17.55.
I have a richedit containing lines using different fonts, styles, languages etc.
I am drawing in a gutter. I would like to start my drawing at the same y pixel position as the corresponding line.
Send the control an em_PosFromChar message. It returns the client coordinates of the character at the given index, although the documentation doesn't say what the coordinates represent (upper left corner, baseline center, or what). You're looking for the character's baseline.
Use em_LineIndex to get a character index for a given line number, if you don't already know the index of a character you're interested in.
Hi I'm using LateX. I have a block of text that I'd like to have a small box like space highlighting the are (just like a \begin{equation} but for text).
Is there such a thing in LateX?
I'm not 100% sure what you're asking I'm afraid, but if you just want to indent text with a margin on each side of the page to make it stand out, you can use...
\begin{quotation}
Quotation is good for long blocks of text that you want highlighted
\end{quotation}
\begin{quote}
Quote is suited to a single block of quoted text.
\end{quote}
If you actually want to have a physical black box around the text, you might want to consider wrapping it in a tabular / table, or you might want to delve into minipages and/or par box environments...
Is \makebox what you're looking for?
To create boxes of text that behave differently from the rest of the text, we can use
\makebox[width][pos]{text}
The width sets the width the of the box. The pos sets the positioning of the text - either r (right justified text), l (left justified), or s (stretched to fill the box). If the pos parameter is left out, as in \makebox[1in]{centerme}, the text is centered. The text is placed in the box. If you want to draw a box around the text, use \framebox just as you would use \makebox.
\mbox{text} and \fbox{text} are quick versions of \makebox and \framebox, which create a box to fit the size of the text.
