Visualize moving average and standard devaition of daily count

I'm working on twitter data and I search the tweet text using some key words (such as word 'flu'). Then I generate date_histogram of daily counts of the tweets which contain the search key words ('flu') and visualize it in Kibana. Is there any way that I could plot the moving average of the daily counts (say, 7 days moving average) and upper control limit in Kibana, so that I could find the days that have higher number of counts than other days? Thanks.

There is no moving average support in Kibana currently (though it was just introduced as experimental in Elasticsearch). Feel free to raise an enhancement request, if this is important to you:
