[Celinux-dev] Fun python project (svgchart) free to a good home

[Gross, Mark]

Now, I'm not saying I'll do anything with this but....

If there were some more descriptive requirements or use cases, and
examples of input data and type types of plots that are expected to
squirt out of this code that would help.  

Also, what's not finished with this thing?  It makes some plots.  
>>> from svgchart import *
>>> x.setData(svgchart.linetestdata[1], svgchart.linetestdata[2],
svgchart.linetestdata[3])
>>> x.setLabels(svgchart.linetestdata[0])
>>> x.draw()

<svg version="1.1" xmlns="http://www.w3.org/2000/svg">
<rect width="320" height="240" style="fill:black"/>
<polyline points="10,50 60,50 110,30 160,20 210,20 260,25 "
style="stroke:white;stroke-width:2"/>
<polyline points="10,80 60,70 110,65 160,60 210,70 260,130 "
style="stroke:red;stroke-width:2"/>
<polyline points="10,120 60,110 110,105 160,100 210,100 260,90 "
style="stroke:yellow;stroke-width:2"/>
<line x1="10" y1="230" x2="10" y2="240"
style="stroke:white;stroke-width:2"/>
<line x1="60" y1="230" x2="60" y2="240"
style="stroke:white;stroke-width:2"/>
<line x1="110" y1="230" x2="110" y2="240"
style="stroke:white;stroke-width:2"/>
<line x1="160" y1="230" x2="160" y2="240"
style="stroke:white;stroke-width:2"/>
<line x1="210" y1="230" x2="210" y2="240"
style="stroke:white;stroke-width:2"/>
<line x1="260" y1="230" x2="260" y2="240"
style="stroke:white;stroke-width:2"/>
</svg>

Is it only the data API for sucking in data to be graphed?
  
BTW its missing an ability to handled (x,y) pairs of input data. (The
current line code assumes a fixed step size between x values in the data
list of y values.)

The esthetic quality of plots created in this way are unlikely to be
competitive against the output of other tools that create jpg's or png
images.  However; I do believe they will be "good enough" to express
some results.
