Is this what you want -- one set of bars and a line independent of those bars?
http://chart.apis.google.com/chart?chs=700x300&cht=bvs&chm=D,FF0000,1,0,5,1&chd=t1:80.14,11.28,63.69,100.0,17.13|30,30,30,30,30&chxt=x,y&chxl=0:|16.Jan||18.Jan||20.Jan&chtt=Activity+a+day&chbh=a&chxr=1,0,180.0 I added a '1' after the 't' in chd. This specifies the number of series with bars, and then the remaining series (the second series in this case) are only used as invisible guides for markers (the line from chm=D in this case). For more information, see http://code.google.com/apis/chart/formats.html#multiple_data_series -- chart data series option http://code.google.com/apis/chart/styles.html#line_styles -- first chart example in the chm=D box If you just want the data scale in the chart to match the axis scale chxr=1,0,180, you need to add chds=0,180.
