Somewhat complicated but here's an idea that might work. A gantt chart is basically a multi dataset horizontal bar chart with gaps and a few data point labels. I know that's over simplified and if your chart is complicated then your url will be really long but it should work
see this example without data labels but illustrative of the technique. Basically, repeating the colors for each datapoint of each dataset but substituting the chart background color (in this case FFFFFF) for where you need the gaps gives the illusion of a gantt chart. http://chart.apis.google.com/chart?cht=bhs&chco=000000|000000|FFFFFF|000000|000000,FFFFFF|0000FF|0000FF|FFFFFF|0000FF,FF0000|FF0000|FFFFFF|FF0000|FF0000,00FF00&chd=t:1,5,6,8,4|5,6,10,4,2|5,6,10,4,2|1,5,6,8,4&chs=1000x300 --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Chart API" group.
