Progress Report for the week of December 4, 1997

Accomplishments:

In the last two weeks, we have been able to implement the brush in a limited fashion. In our original design, the brush was defined by a center point and a size. We have decided to change this and define it as a max and min. Finding the center is less computationally intensive with this method than it is finding the max an min with the center and size methods. It's also easier to grasp conceptually, I believe. As far as implementing direct manipulation, it works in a very primitive fashion in Parallel Coordinates. I am having problems with redrawing the screen still. I can't pin down why it's behaving like it is. Will and Jason have made some progress on their graphs, but they do not support the brush yet. We have found a way to determine how big the graph should be. It's going to be based on the screen resolution. When the program is maximized, it will fit in the window perfectly when the zoom is 100%. When we zoom to 200%, the graphs draw on a canvas that is twice as big. Problems would only occur if the user changed the screen resolution while the program was running, which isn't too likely. It wouldn't crash, it would just draw the pictures bigger.
