Position g Drag plot (shift h)

In the "drag plot" mode you can pick up all selected plots with the mouse and drag them over the graph.

Shift mode

Shifts the plots while you are dragging them. By doing it in drag plot mode instead of using the shift command, you can instantly see what happens to your plot while you are shifting it.

 
Shift Y: the plot is shifted while it is being dragged

Multiply mode

Multiplies the plots while you are dragging them. By doing it in drag plot mode instead of using the multiply command, you can instantly see what happens to your plot while you are multiplying it.

 
Multiply Y: the plot multiplied while it is being dragged

Point of origin

In multiply mode, you can select a point of origin. By selecting a point of origin other than zero (the default), you can expand or contract a plot which has an offset, without multiplying the offset as well.

Numeric vector indicators

In the top left corner of the graph panel the dragged amount is displayed, the momentary value as well as the cumulative shift vector and the cumulative multiply vector (when several drags were done on the same plot). 


The dragging vector indicators

When you click on the indicators of the cumulative vectors, you can specify your own cumulative vector: entering X=0 and Y=0 here in the shift indicator, or X=1 and Y=1 in the multiply indicator, will result in the plot jumping back to its original location. 

When you click on the indicators of the momentary value, you can specify the next dragging operation: entering X=0 and Y=0 here in shift mode, or X=1 and Y=1 in multiply mode, will result in the plot staying exactly where it is at the moment. 

Changing modes

You can change modes in the menu with the corresponding menu item or the corresponding shortcut keys. You can also change modes with the mouse. If you press the ctrl-key before you start to drag a plot, the mode changes to multiply. If you press ctrl-shift when you start to drag a plot, the mode changes to shift. The direction (X, Y or X and Y) will not change when you change modes with the mouse.

Cursor keys

The plots can also be shifted around by the cursor keys. You can change the amount of shifting per-key-press by pressing ctrl-F, or by choosing "change fraction" in the "Cursor keys" menu. The fractions can also be changed interactively by pressing the "+" key or the "-" key. "+" Multiplies the fractions (of both X and Y) by 2, shift-"+" multiplies the fractions by 10. 

Selecting only part of a plot

If you draw a rectangle before choosing the draw plot command, only the parts within the rectangle will be shifted/multiplied. If you use the selection rectangle, you will not be able to select other plots or parts of it until you exit the draw plot mode completely.

 
Only the part within the rectangle is shifted   

Dragging in tiny amounts

If you want to drag your plot with smaller amounts than one pixel, you can change the dragging factor. Alt+ multiplies the factor with 2, alt- divides it by 2 and alt-1 resets it to one. Every mode change will reset the dragging factor to one as well.

Exit drag plot mode

Exit this mode by escape or right-clicking with the mouse. When you choose "undo" after exiting this mode, all shifting or multiplying operations done during this mode will be undone.
