A new tag has been implemented to display history panels in custom pages, integrated in the 
new custom page design from 2017. The full documentation can be found at 

https://midas.triumf.ca/MidasWiki/index.php/New_Custom_Pages_(2017)#mhistory

Attached is a simple example of such a panel and the result. You have to rename triggerrate.txt to triggerrate.html if you want to use it (can't do it here since otherwise the browser wants to render it which does not work outside of midas).
