This might be a hard thing to code but i suggest it in case it is not.
In market graph window, clicking or floating over a day, you are able to see all the info for that day, just as it is when you float you mouse over “median price dots”.
The information you see would be volume, max and minimum, median and date.
Obviously you can see all this in table mode but it would be nice to not switch between the two all the time and to be able to have all the info in graph mode.
