I'm trying to show some text on top of a plot. Using
text(13,15200,('~ 12h'),'HorizontalAlignment','right','VerticalAlignment','middle','FontSize',10,'FontAngle','italic');
I can create the text box how I want it. But a thing I didn't manage to do is to create a carriage return within that text object. Already tried to add '\r' or '\n' but the only thing I get is the display of '\r' or '\n' with out breaking the line. Any ideas?
And i now that text object are used to put text WITHIN axes. But I am still trying to find a way to put some text outside the grap. Searching stackoverflow I found this Post about using UICONTROL. It works great but when I export to EPS the text seems to be in pixel format and NOT vector - so it looks really bad. Is there another way besides using uicontrol??
Thanks a lot for help!
In text that is not interpreted, you can specify line breaks using the carriage return character, which has the ascii code 10.
text(x,y,sprintf('break after this%snew line here',char(10)));
To allow text outside axes, you need to turn off clipping for the text object
text(x,y,.....,'clipping','off')

I searched everywhere for this, the problem is that the search criteria is very similar to other questions.
The issue I have is that file (script actually) is embedded in another file. So when I open the parent file I can see the script as massive string with several \n and \r\n codes. I need a way to convert these codes to what they should be so that it formats the code correctly then I can read said code and work on it.
Quick snippet:
\n\n\n\n\nlocal scriptingFunctions\n\n\n\n\nlocal measuringCircles = {}\r\nlocal isCurrentlyCheckingCoherency
Should covert to:
local scriptingFunctions
local measuringCircles = {}
local isCurrentlyCheckingCoherency
perform a Regex Find-Replace
Find: (\\r)?\\n
Replace: \n
If you don't need to reconvert from newlines to \n after you're done working on the code, you can accomplish the trick by simply pressing ctrl-f and substituting every occurrence of \n with a new line (you can type enter in the replace box by pressing ctrl-enter or shift-enter).
See an example ctrl-f to do this:
If after you're done working on the code you need to reconvert to \n, you can add an invisible char to the replace string (typing it like ctrl-enter invisibleChar), and after you're done you can re-replace it with \n.
There's plenty of invisible chars, but I'd personally suggest [U+200b] (you can copy it from here); another good one is [U+2800] (⠀), as it renders as a normal whitespace, and thus is noticeable.
A thing to notice is that recent versions of vscode will show a highlight around invisible chars, but you can easily disable it by clicking on Adjust settings and then selecting Exclude from being highlighted.
If you need to reenable highlighting in the future, you'll have to look for "editor.unicodeHighlight.allowedCharacters" in the settings.
I am trying to display text over time using altair (vega-lite), which works fine using a layered chart, where one is created using the alt.Chart().mark_text() function to display the text.
The text though is multiple phrases and should be wrapped (with line breaks). How can this be done?
(I do not want to use fixed line breaks, e.g. \n, at distinct positions since the text wrapping should work with zooming too)
Not exactly what you want, but you can specify a character on which to break to a new line. When zooming, the text stays the same size, so it should always fit the view.
For example making a new line for every word:
.mark_text(lineBreak=' ')
I want to add small straight line onto some desired characters/numbers inside a string inside textview. I couldn't find a solution. Maybe using NSMutableAttributedString. Meanwhile, I mean doing this programmatically. There is strikethrough style, but not overstrike style. Or maybe adding the letters "a" and "_" with different .baseline values. But how to add both characters onto each other then?
Is it possible?
EDIT: Due to make a try for the helpful answers below, I think to make the line at a spesific height is needed. "A\u{0305}" makes the up line very close to the character, as if it sticks. Is there a way to make it at specific height? For example, if we assume that all the keyboard-inputted characters are written inside every single boxes, the ceiling side of these boxes could be lined?
So this (note: see edit below) appears to be an "a tilde ogonek" (it's Lithuanian).
You can write it for instance as follows using these two Unicode characters:
let atildeogonek = "\u{0105}\u{0303}"
let title = "How to add a small straight line (I mean like this: \(atildeogonek)) onto a character inside a string?"
The first character is the a with an ogonek, the second one is the tilde.
EDIT: The initial question specifically asked about the character ą̃ ("a tilde ogonek") in the title, and I used this code to demonstrate how to use Unicode characters in a Swift string. After posting this answer, the question was edited to be more general about "a line above a character".
Programmatically, you could use a function like this:
func overline(character: Character) -> Character? {
return "\(character)\u{0305}".first
}
That will take a character as input and return a new character (glyph) that has had the Unicode combining overline character added to it. It will return nil if adding the combining overline character fails.
The code print(overline(character:"A")!), for example, returns "A̅"
Or, if you want to add an overline to every character in a string, you could use a function like this:
func overline(characters: String) -> [Character?] {
return Array(characters).map { return "\($0)\u{0305}".first
}
}
(I'm not sure if there are any characters for which the above will fail, so I'm not sure if force-unwrapping the result is safe. Thus I left the result of both functions to be optional Character/Array of Character.)
You can easily find the unicodes of ā or ą̃ by using the xcode's own Character Viewer. Just follow the following steps :
hit : Control + Command + SpaceBar
If you get a compact one like this, click the upper right corner icon to expand it.
When expanded, Click the settings gear in the corner . Select customize list.
select Enclosed Characters
Go down to the bottom and open Code tables then add Unicode.
Now, just search for your required Character and you can check its unicode value. here i am searching ā
to print unicode's value :
print("\u{0101}")
I am trying to use the libreoffice formula editor to add some formulae to drawings in libreoffice draw.
However, whenever I want to enter a formula that LO thinks is wrong it places an ugly upside-down question mark or a box with nothing in it.
MWE:
%sigma^+
I want to denote the light polarization to be right-circular polarized, hence there should be nothing behind the + sign. However, LO decides a + sign should be followed by something and adds in an ugly placeholder.
In LATEX I would write
\sigma^+
and be done.
How do I get rid of the placeholder?
You should type it with double quotes, that is
%sigma^"+".
I have a MATLAB program I am developing in order to do some image processing stuff and need to use a user control into a MATLAB GUI user interface I created ad-hoc.
This user control is a List Box and there I would like to insert some text. Well the problem is not that I cannot put text there, I can do that using this call:
set(handles.mylistbox, 'String', 'MyStringToPrint');
Well the problem is that this call does not let me insert many lines in my list box but just overwrite the previous one.
I wish to find a way to let my code insert the new text in a new line. This should not be so difficult to do and it is also a simple pattern:
texttoprint = 'My text to add'
oldtext = get(handles.MyListBox, 'String') %Holding the previous text here
set(handles.MyListBox, 'String', [oldtext '\n' texttoprint]) %Setting (no line feed printed)
set(handles.MyListBox, 'String', [oldtext char(10) texttoprint]) %Setting (this fails too)
Well it is ok and it does not raise any error BUT, \n DOES NOT WORK.
I do not have any new line... BUT NEED TO!!!!
How should I solve this?
The problem is that I need to print text in this user control, not on the MATLAB commandline (that is very simple just by doing sprintf()).
What to do? Thank you
For a listbox, set the string property to a cell
set(myListboxHandle,'String',{'myFirstLine';'mySecondLine'})
If you want to add another line, call
contents = get(myListboxHandle,'String');
set(myListboxHandle,[contents;{'another line'}])
For multiline text in GUIs otherwise, use char(10) instead of \n, i.e.
set(someUiControlHandle,'String',sprintf('my first line%smy second line',char(10)))
When working with list boxes it's usually easier to deal with the options as a cell array of strings. So, you would initialize your list box as follows:
set(handles.MyListBox,'String',{'Option 1'});
And then you can add options to your list box like so:
newOption = 'Option 2';
oldOptions = get(handles.MyListBox,'String');
set(handles.MyListBox,'String',[oldOptions; {newOption}]);
