I want to make an area chart with Google’s Chart API, but it needs to be the PNG format one so I can build a PDF. Is that possible? The Chart Wizard does not seem to support area charts. Also, I want to do it in perl and the URI::GoogleChart module.

    I spent a lot of time on this and discovered that I can do this:

    See the example visually or the code below:

    http://chart.apis.google.com/chart
   ?chxl=1:|week1|week2
   &chxp=1,20,90
   &chxr=0,0,120
   &chxs=0,676767,11.5,0.5,l,676767|1,676767,9.5,0,_,676767
   &chxt=y,x
   &chs=300x278
   &cht=lxy
   &chco=FF9900,FF0000
   &chds=6.667,100,0,110,0,100,0,118.333
   &chd=t:-1|110,80|-1|43,32
   &chdl=Total+Num|Special+Num
   &chdlp=t
   &chg=1,-1,1,0
   &chls=2|2
   &chma=8,0,0,7|54,2
   &chtt=%23+Total+and+%23+Red+Items
   &chts=000000,11.5
   &chm=b,FF9900,0,1,0|B,FF0000,1,9,0

    Where the last line b,color,startLine,endLine,0 means fill down to endLine and B,color,startLine,arbitraryNumber,0 means fill down to the bottom of the chart.

    The solution came from Google’s docs with some experimentation.
