Display

• Introduction: The Display is the portion of the screen that shows the data.
• Arrows: MMDISP shows the magnitude, direction and location of a spatially distributed set of data. The data points can have components of magnitude in three dimensions but the location of the data points is confined to two dimensions. The position of the arrows in the plane mirrors the distribution of the data points. The data's in-plane component's magnitude is given by the relative length of the arrows. The direction of the arrow shows the direction of the data's in-plane component. If the in-plane component's magnitude is too small or if the frame size is too small to draw recognizable arrows, the arrow will be displayed as a box.
  • Color of Arrow: The color of the arrow shows the magnitude of the out of plane component of the data. If only an in-plane component exists, The color of the arrow is black. If only a positive out-of-plane component exists, the color of the arrow is blue. If only a negative out-of-plane component exits, the arrow is red. If both an in-plane and an out-of-plane component to the data point's magnitude exists, the intensity or of the blue or red will reflect the relative strength of the out-of-plane component.
• Frame size: The frame size is the size of the window needed to display all of the data at the current zoom and subsample factors. The frame size can be smaller or larger than the window size.
• Window size: The window size is the size of the region that is viewing the data. The window size can be smaller or larger than the frame size. If the frame size is larger than the window size not all of the data in the frame can be displayed in the window. The window can be scrolled to allow viewing of different parts of the frame. If the frame size is smaller than the window size, part of the window will be empty. The window size can be adjusted by clicking and dragging on a corner of the window or with the command wrap display.
• Navigating: The display can be zoomed and moved using the mouse, control bar and keyboard.
  • Mouse Commands:
    • Zooming: The mouse is used to zoom by left clicking on a corner of the area to be zoomed. Drag the mouse until an area is outlined in red and then release the mouse button. The zoom factor will be adjusted so that the area in red fills the current window. The same action using the right mouse button will zoom out. In this case the area will be outlined in blue and the zoom factor adjusted so that the data that filled the window will now fill an area in the window the size of the blue box. The arrows on the side of the rectangle show the edge that will control the size of the zoom.
    • Moving the Window: If the window is smaller than the frame the window can be moved over a different part of the frame using the side and bottom scroll bars. The bottom scroll bar moves the window right or left and side scroll bar moves the window up or down. To use the scroll bar click on one of the arrow keys or click on the scroll bar and then drag it to the required point.
