Static behavior
The display is scaled in the available place in the viewer, and rescaled each time this place is changed. It will draw everything in black on the black and white screen and use various colors on the color screen, as in the InterPress master.
User Modifications of the display
The User can change the picture by clicking the scrollbars or the menu buttons or by clicking the mouse inside the viewer.
The Horizontal scrollbar translates the x origins of each axis of an equal proportion of their width. If the application is wise enough to keep all axis width equal, the same translation is applied to all axis. The Vertical scrollbar has the same effect on each y origin of each axis.
The menu has the following buttons :
Reset : resets to a full display.
Mag : switches in or out the magnifier, a zoom feature (the 2nd time base of the oscillo)
Grat : draws a scale along x and rounds the x scale to be a "decimal round" number.
Shot : takes a picture of the screen and stores it in ///Temp/PlotGraph/**name**.interpress
Frozen: switches on or off the interactive refresh of the screen by the client program.
sizeX: LEFT click double, RIGHT click divide by two the x scale of the normal display.
MagSizeX: Id for the x scale of the magnifier.
sizeY: Id for the y scale of normal and magnifier displays.
