Re: [swtchart-dev] GSoC 2020:Exporting *.svg files via Inkscape

[Philip Wenig <philip.wenig@xxxxxxxxxxxxx>]

    Hi Yash,
    
    the current SVG export is fine and uses Apache Batik and other
    dependencies to export the data.
    
    I would like to have a second solution without using these
    dependencies, via a template. The template for Bar-, Line- and
    Scatter-Charts shall define one x and one y axis, which is populated
    by the export script. The line series shall be exported as "one"
    connected line instead of separate elements.
    
    
    Best,
    Philip

Hi,

I looked into how Graphics2D generated the .svg export for different charts and found 

that it consists of three sections of code-

1) General declaration of  xml document and SVG object,this will be common to all templates.

for e.g-

<svg>

<g>

<defs id="defs1">

<clipPath clipPathUnits="userSpaceOnUse" id="clipPath1"
      ><path d="M50 50 L876 50 L876 317 L50 317 L50 50 Z"/>

</clipPath>

</defs>

<g style="fill:red; stroke:red;" transform="translate(50,0)"

2) Filling of data series in the chart ,this is the only section of code which differs in the template of each chart   

for e.g. -

in line chart it is done as -

<line x1="50" x2="50" y1="316" style="fill:none; clip-path:url(#clipPath1);" y2="316"/>

3) Defining the axes and giving effects to the chart,this will depend on the data series the user is exporting.

Does this look fine?

Thanks,

Yash
