It is very easy to use in terms of UI (User Interface) as well as its features are quite handy too! I personally haven't used any other charting software so far but after using this one it's really hard for me to say anything negative about it because i have nothing majorly bad or good to tell you guys that can make you not want to go with zenchart charts!! The best thing about this app would be definitely their free version which gives us all we need right from scratch at no cost; moreover when there comes an upgraded package then they charge just $29 per month. So if budget allows why don't try them out once right away? Also i must mention here how awesome the support team behind these tools actually is. They always come up whenever required even 24/7.
