What can be done

The available capabilities are as follows:

  • Framing on the two axis (zoom)
  • Framing on one axis (zoom on an axis)
  • Translation of the visualization window

Pointer operation

The pointer operation modes (of the mouse) in the display zone are presented in the table below.

Zoom
  • zoom by framing of a zone

0 Activate the zoom mode
1 Click on the desired place in the tracing area and maintain the click
2 Move the cursor to define the desired area
3 Release the click

Step Action
0 Activate the zoom mode
1 Click on the X or Y axis at the desired departure point and maintain the click
2 Move the cursor on the axis up to the desired position
3 Release the click
→

The zoom is done only on the chosen axis, with the other axis remaining at the same scale

For a zoom on the axis X, the zoom has impact on each elementary curve

For a zoom on the axis Y, the zoom is only carried out on the selected elementary curve (only in the display modes « lit» and « sorted out by formulas »)

It is equally possible to zoom on one axis by activating the box « Choice of pins » (click right on the desired axis).

Initializing a curve

The user can retrieve the initial framing (initial scales) of an elementary curve by clicking on the button

Each elementary curve has its own reset button

Translating the visualization window

To translate the visualization window:

Step Action
0 Carrying out of a zoom
0 Activate the Translation mode
1 Click ..

It is equally possible to translate the visualization window on an axis by activating the box « Choice of pins » (click right on the desired axis).
