Combining style, interval and certainty in Google Charts

[David Hyde]

Hi. Have a look at https://jsfiddle.net/DavidHyde/fkuonb5s/. This is based on an example from the Google Charts documentation along with the code that I'm running. I didn't write the code and am not a Charts expert by any means, so don't understand all the code yet, but I'm getting to grips with the data definition format.

Anyway, I'm having trouble combining the style, interval and certainty roles. It seems that I can apply any one, but when I have two or more, only the first is applied.

Specifying "certainty" gives this:

Applying "style" gives this:

and this is just "interval"

What I really want to do is apply the certainty role for the hatching, and the interval role for the horizontal bar.

Can anyone help? Thanks

Hi David,

Your chart works fine if you include all your data columns in the DataView columns.   Here it is with the necessary change:   https://jsfiddle.net/dlaliberte/cvu3t7se/6/

The 'annotationText' seems to not be working, however.  Maybe this particular way of rendering the annotation interferes with showing the annotationText (which is like a tooltip for the annotation). Changing it to 'tooltip' at least shows that the text is in the data.

Many thanks - I will apply your suggestions in my production code and see how it goes.
