annotate

In the following setup, I'd like a QuerySet with a list of projects, each annotated with the sum of all its task durations (as tasks_duration) and the sum of all of its tasks' subtask durations (as subtasks_duration). My models (simplified) look like this: class Project(models.Model): pass class Task(models.Model): project = models.ForeignKey(Project) duration = models.IntegerField(blank=True, null=True) class SubTask(models.Model): task = models.ForeignKey(Task) duration = models.IntegerField(blank=True, null=True) I make my QuerySet like this: Projects.objects.annotate(tasks_duration=Sum(

How can you include annotated results in a serialized QuerySet? data = serializer.serialize(Books.objects.filter(publisher__id=id).annotate(num_books=Count('related_books')), use_natural_keys=True) However the key/value pare {'num_books': number} is not include into the json result. I've been searching for similar questions on the internet, but i didn't found a solution that worked for me. Here is a similar case: http://python.6.x6.nabble.com/How-can-you-include-annotated-results-in-a-serialized-QuerySet-td67238.html Thanks! I did some research and found that serializer.serialize can only

I'm trying to use annotate but have a problem: The output ignores some information (date and username) if it was displayed for the same version before. I'd like to display them in any line. This is my command: cleartool annotate -out - -rm -nhe -fmt "%Sd ||| %-12.12u ||| %Vn ||| ,,%Vn ||| " -rmf "" "G:\views\myview\myprojectvob\Form1.frm@@\main\john_myprject\12" That's the output. I'd like to get date and username for the second and third lines as well. Do you know if that's possible? 2008-05-22 ||| john ||| \main\john_myproject\10 ||| End Sub \main\john_myproject\10 ||| \main\john_myproject

I am using matplotlib.pyplot.annotate to draw an arrow on my plot, like so: import matplotlib.pyplot as plt plt.annotate("",(x,ybottom),(x,ytop),arrowprops=dict(arrowstyle="->")) I want to use an arrow style that has a flat line at one end and an arrow at the other, so combining the styles "|-|" and "->" to make something we might call "|->", but I can't figure out how to define my own style. I thought I might try something like import matplotlib.patches as patches myarrow = patches.ArrowStyle("Fancy", head_length=0.4,head_width=0.2) (which should just be the same as "->" for now; I can tweak

I would like to annotate my plots with a filename. With plot() I used mtext : plot(1:10) mtext("File xy-12-34-56.csv", 4) How can I do that with ggplot2 and qplot or ggplot? It should not collide with the legend. I found the commands annotate and grid , but I could not get an annotation similar to mtext with these. As a workaround I could try watermarks , but perhaps you have a good hint for me. Kind regards, Jonas Update Looks like to achieve the result now we should use the following: library(ggplot2) library(grid) library(gridExtra) p <- qplot(data = mtcars, wt, mpg) grid.arrange(p, right =

I need to annotate an image with Chinese Text and I am using Imagick library right now. An example of a Chinese Text is 这是中文 The Chinese Font file used is this The file originally is named 华文黑体.ttf it can also be found in Mac OSX under /Library/Font I have renamed it to English STHeiTi.ttf make it easier to call the file in php code. In particular the Imagick::annotateImage function I also am using the answer from "How can I draw wrapped text using Imagick in PHP?" . The reason why I am using it is because it is successful for English text and application needs to annotate both English and

The Imagick library in PHP allows you to draw text on top of an image. How can I tell Imagick to wrap the text based upon some bounded text box, so that the words appear as multiline text rather than a single line? Usage: list($lines, $lineHeight) = wordWrapAnnotation($image, $draw, $msg, 140); for($i = 0; $i < count($lines); $i++) $image->annotateImage($draw, $xpos, $ypos + $i*$lineHeight, 0, $lines[$i]); Function: /* Implement word wrapping... Ughhh... why is this NOT done for me!!! OK... I know the algorithm sucks at efficiency, but it's for short messages, okay? Make sure to set the font
