Hi, 1. Go to http://code.google.com/apis/chart/image/docs/chart_wizard.html and click on the vertical bar chart (top right corner with the green vertical bars). 2. Expand the "data" bar. You will find 2 data sets inside, data set 1 and data set 2. Have encoding set to "text" by clicking that button. 3. Notice that the "&chd=t..." field is highlighted indicating that that is the data field. Notice that chd=t: changes to chd=t1: when either of the "visible" boxes are checked. The chart on the wizard page also changes. 4. When pasted, the URL created shows a chart exactly like the one shown on the wizard page whether or not the data is "visible". e.g. if both sets are visible, both sets of columns appear. If one set of data is visible, only that set appears. 5. Now, when you click on "embed with visualization API", you get full html to load the chart using javascript. Save an html page (just copy and paste the entire contents) with both sets set to "visible" and another html page with only one set to "visible". You will notice that the "chd" parameter changes as expected, but the pages' charts show up identically in the browser. The expected result is two different charts like the pasted URL gives you.
Let me know if this makes sense. Thank you. On Aug 3, 4:41 pm, duniyadnd <[email protected]> wrote: > Can you provide an example?
