Dynamic statistics application missing

[math7]

I think there is something that maybe some have overlooked in the HP Prime, but I think it is necessary and useful to include it in the development team. As the competition does, the Prime should be able to relate the data for example in the application of statistics of 2 variables and that when plotting them could split the screen into 2 parts, in a half show the data that have been entered into the columns and in the other half show the graph of such points. It would then be useful to be able to see the change by dragging a point in the graph for example and see how the value changes in the column and row concerned; or conversely, when changing a value in the columns see how this affects the position of the point in the graph.
For example in the application of Geometry when drawing any object such as a square, and put a tag with the square area, if you move one of the points of the square the value of the area also changes, this is very useful to see the change dynamic of values and figures; but this functionality does not exist in the application of statistics. For example, it does exist in the function application, because the screen can be divided into two parts, one to display the graph of the function and another part shows a table with the values of "x" and "y".
Another observation: it would be very good if the application of Geometry could import graphics of the Advanced Graphics Application, to be able to import those graphics and to manipulate them or to add other figures or points in the application of Geometry but at the moment this is not possible.
