A histogram is related to a bar graph and is meant for quantitative data (number data only instead of word data). A histogram is constructed by drawing a rectangle for each bin. Bins are intervals of equal width that cover all the values that were observed in the x-axis.

I wanted to know if Doceri was able to use the Apple Pencil with the iPad Pro. I was surprised that it handled well. Doceri is not optimized for the iPad Pro nor is it for the Apple Pencil, but with some adjustment like 200% scale, I was able to draw some items.
Please write your comments on how you use Doceri. Tell us what you would like version three to have.

Divide and Conquer. This is another area that is very industry-dependent, but it is highly unlikely that any company can afford to have an entire contract team devoted to managing one portfolio. More than likely, it is more realistic to divvy up the team and the contracts so that there is a leader for each relevant sphere. The entire team will obviously have to coordinate and communicate, but resources must be allocated in the most efficient manner possible. In turn, this will allow for several individuals to keep an eye on a smaller batch of contracts, thereby facilitating those periodic reviews. Outsource the Tedium to Technology.
