NOTICE: This Article is updated for 0.9w3
I recently update my TurboGears PlotKit widget.
This version(0.9w3, 0.9 is origin lib's version, w means 'widget')
To get these widgets, easy_install them :
$easy_install plotkit
Then, you can Check the demo in TurboGears toolbox :D
How to try it? Well, it's extremely simple.
For a fresh quickstart site,
In controllers.py:
from plotkit import EasyPlot
class Root(controllers.RootController):
@expose(template="wgtest.templates.welcome")
def index(self):
setA = [[0,0], [1,2], [2,3], [3,7], [4,8], [5,6]]
setB = [[0,0], [1,1], [2,4], [3,8], [4,7], [5,20]]
setC = [[0,1], [1,3], [2,5], [3,5], [4,3], [5,2]]
return dict(ep= EasyPlot(id="diag",
style="line",
width="300",
height="300",
data=[setA, setB, setC]))
In welcome.kid:
${ep.display()}
add this script into html "body".
Explain:
from plotkit import EasyPlot
First of all, import the proper widget. (origin PlotKit widget is still availbe)
return dict(ep= EasyPlot(...))
return the "ep" diagram instance to template
${ep.display()}
display the diagram in template
Parameters:
id: (diag)
The Diagram's Identifer (Element ID)
style: (line)
The diagram could be plot as a "line", "pie", or "bar"diagram.
width, height : (400, 400)
The diagram's size
data :
Datasets is structured with [[x,y],[x1,y1],....]
option :
options of both Layout and Renderer (dictionary style), need be a string
The origin example is here.
History
0.9w3 07/04/2006: more flexible EasyPlot dataset
0.9w2 : fix bugs and add a EasyPlot() widget to plot a diagram within the code.
The svn repository is in Sourceforge, you can share your TurboGears widget there, too.
known limit:
current widget's option param suppor is not very OO, you need pass the dictionary in string format (can't recognize "v", "label")
