I'm sorry you don't like it, but it's the only way to do it, years by number of exchanges and the total of all.
I do not understand your comment.

There are rules for proper data analysis.

How to create a graph chart for "proper" data analysis.

https://www.google.com/search?client=firefox-b-1-d&ei=5gv-XZzjFNX0tAa91o-YAQ&q=How+to+create+a+chart+for+%22proper%22+data+graph+analysis.&oq=How+to+create+a+chart+for+%22proper%22+data+graph+analysis.&gs_l=psy-ab.12...140543.144285..146520...0.4..0.113.896.7j3......0....1..gws-wiz.......0i71j33i10.VAw2djJvhy0&ved=0ahUKEwic7s2I28bmAhVVOs0KHT3rAxMQ4dUDCAo

The last bar presents the total of all of them, any graph should be carefully observed and read the data, not just looking at the colors. Cheesy

But if this is the norm (I don't know) when I publish the finished graphic, I will remove the totals bar.

thx

edit:

that's better?

Nice graph.

That being said, I think the number of hacked exchanges per year is not taking into account the increase in number of exchanges. It would seem that security/risks is getting worse, when maybe it is the contrary. I would suggest to compare the figure of "hacked exchanged / total number of exchanges active in that year". That would probably give a better overall view of how security is progressing. And show how in the first years probably there were even more hacks than exchanges active (repeated hacks).

Yes, it would be an interesting fact to consider, but I don't think it is possible to know the number of active exchanges per year.
Logic would be as you say, last years more security, but hackers have also reduced the number of targets for their attacks,
they focus on hacking high volume exchanges and this reduces the amount of exchanges that meet this feature.
