textbp: text with legend-style "best" placement

automatically locates text annotation to minimize figure obscuration

File Information
Description

Sometimes the exact location of some text annotation doesn't matter. This works just like TEXT (including the property calls) except one does not specify an X,Y location. The subroutine TSCAN (modified from the Matlab LSCAN routine) automatically places the text, with a preference for the bottom/left corner.

MATLAB release MATLAB 7.2 (R2006a)
Other requirements none

same issue as Matthew Crema
- no subplots
- the problem is "tscan"

"Undefined function or variable "pop".

Error in tscan (line 136)
minpop = min(min(pop));"

It does not work for me, and the error message is:

Undefined function or variable "pop".

I have a lot of subplots in one figure, which may make the task difficult.

Ian -- legend tends to take the best upper-right position, while textbp looks for the best lower-left position. If your plot is fairly dense with data, they may decide on the same spot. textbp only pays attention to the data, it doesn't know where the legend is placed.

Alireza -- this is hard to debug without the error message. I'm going to guess that you put it somewhere where it's not in your path. Try "which textbp" or "path".

It doesn't work for me but maybe I'm doing something wrong. I added the folder in the toolbox folder of Matlab and I'm using textbp('some string') after I plot some data. Is that right?

This works well on its own, but it does not seem to play well with the legend command (MATLAB R2013a). Both legend and textbp choose the same overlapping 'best' spot.

Jamal -- As I recall, that's related to a problem that occurs when translating between figure and axis normalized coordinates. I took it up w/ Mathworks years ago, with no satisfactory resolution, so there it stands.

Adrien -- the trick is to rejigger TSCAN so it goes from top-left to bottom-right. I'll do that if I can find some time. It's been a long time since I looked at the code!

I can't figure out how to use this code. Does this need to be placed in each .m file I wish to use the textbp function in?

Problem : it does not seem to work with the function "hist". A solution ?

A problem: the repeated using of the function - in its simplest form - causes the overall added texts to be shifted diagonally.

Useful. Should be a Matlab builtin.

This is a great bit of code for what it does. Very easy to use, and exactly what I was looking for.

Beautiful! This code does exactly what I want to achieve. A very nice, simple substiture for the MATLAB text command where hands-off annotation is desired!

25 Jun 2006 Tak Kunihiro

This is a code that I was looking for. Since a command "legend" has similar functionality I even though that there might be a command already. I have been using "legend" to put all information in the plot, which was pain in the neck. Now I can make a plot with all experimental parameters.

Modified TSCAN to properly avoid histogram bars.
