Set different color level when CPU hits high usage

I have been using topbeat to collect data on CPU usage and have created a simple chart for monitoring it, How can I set in kibana that if the CPU Usage rate touches 80%, then the color will be yellow, and 95% for red?

There isn't a way to do this with charts currently. The best option I can think of currently is manually changing the chart color by clicking on an item in the legend. If you're interested in filing a feature request, it can be done at https://github.com/elastic/kibana/issues

How about if I set percentiles range for that? I have tried to set percentile on 80% and 95%, however, they didnt seem to give me the right things though. What does the percentile actually represents?
