@suvoge I think you can make some small changes to meet your requirements on a Knowledge Base code found here,

For more possibilities and opportunities for you to customize a code to meet your needs,

I know next to nothing about charting but with 5 minutes of experimenting, first one could look like top half of this chart, second one I did not have time to make to many changes to but looks like bottom half


thank you. i will try. im also not so good in afl.
