thrdel: True, but then you'd get long bars for periods of inactivity in the market or weekends and really small bars for when the market moves fast.


Ovo:
The only inconvenient may be if the market stays still for days. 

thrdel: You can hardly detect the time gaps on Renko without the underlying chart. On the underlying TF chart may detect gaps if there is no bar within 30 minutes interval after the measured bar period expired.

True but I was more concerned about smaller time frames and bars started before weekend. On a 2 min frame, 2 days of weekend = 1440 of 2 min periods. If a bar on average takes up to let's say 200 minutes to complete or 100 periods and next one includes the weekend, the difference is quite big and makes all other bars look so small.

Thanks thrdel: Thanks. You done did it again.
Here, try this and see how it works : As you can see, time in seconds is divided by the chart period so histogram is not in seconds but multiples of chart period, which means that on an M10 chart for example, 1 unit on histogram = 10 minutes time, 2 units = 20 minutes and so on. 

Hello, I wish I had found this post before spending a weekend writing a version myself from scratch. Originally I wanted to change the colour of candles to indicate the time, even just by simply highlighting bricks that, say, took less than 5 minutes to form on a renko chart. This seemed to be a bit tricky and I couldn't find an easy way to do it or easily change existing code I could find. So I wrote a simple indicator to plot the time differences in seconds. It is here > https://www.mql5.com/en/code/12491 It doesn't quite give the same results as your code. It doesn't try to 'deal' with long bars over market closed periods. Price can move very fast or very slow. If anyone is interested in this or in renko trading systems then I would be happy to hear about it. Thanks and best of luck with your trading! see also / google ~ RenkoAM_v2.0.mq4 indicator 
Yes, by histogram, I mean bars. And what I mean by " kind of difficult reading the individual time stamps.", is basically that it would be easier to analyze Bar Heights than reading vertically printed text.
