Floating Bar Graph(Max/Min)

[kallu]

I have a requirement of a bar graph. There are five questions and for
each question , there are 3 values, a higher value, a lower value. For
each question, the bar should extend from the lower value to higher
value and a marker should be placed at the average value. You can see
the screenshot of the graph needed in
http://stackoverflow.com/questions/5800490/floating-columnmax-min-graph-in-ror

I started looking at the Google charts and found it very useful but I
am not sure whether this requirement can be done with the google
charts. Can anyone help?

Hi,

Bar charts with floating bars are a bit tricky, but your chart can definitely be built. The following should get you started:

Start with a normal bar chart with two data series: first is the bottom of your bar, second is the top:

Hide the first series so it "floats" (see CHCO alpha value)

Add a third data series to position your new marker: (see CHD and CHM)

Cheers,

KeithB,

 

Can you explain what you mean by CHCO alpha value and CHD and CHM ?

 

I'd really like to be able to do this (Floating Bars).

 

Thanks
