DataTable interval role color

[Anuroop]

Hi,

I am using Google Charts DataTable Roles https://developers.google.com/chart/interactive/docs/rolesexperimental feature to draw intervals and annotations in graphs as specified in the above link.

But I want to explicitly specify color of the interval. For example, in the below charts the color of the interval is blue:-

How can I change the color of the intervals to say yellow? I have observed that by default, it takes the color of the curve, for example, the color of the line is blue and hence the color of the interval is blue.

I tried the following approach but failed:-

addColumn({type:'number', role:'interval', color: 'yellow'});

Any help would be very appreciated.

I have the same question. I have tried many different formats but nothing worked.

I'm afraid that's not supported at the moment. You can hack something by drawing 2 lines rather than 1, both with the exact same data, the first line won't have intervals, and the second line will be of some other color (the series option), lineWidth zero, and will have intervals.
