@wer0ckz,
Do you mean showing the number of occurrences of ajax_action (loadmore, blg_preview_action, heartbeat, etc) in chart? If so, then please take a look at this JSFiddle.
In case this doesn’t fulfill your requirement, kindly brief us further about your requirements so that we can understand the scenario better and help you out?
