Moving Around the Graphs

Once a file is displayed the data from the file can be examined more closely using the

following basic functions: zoom, pan and cursor movement.

Cursor

The position of the cursors in the Graph and Graph:Map windows are linked and move

together, and the values displayed in the Graph:Data window update as the cursor is moved

through the file. The left and right arrow keys control the movement of the cursor. If the shift

key is simultaneously pressed then it moves faster across the screen; if the ALT key is

simultaneously pressed then it moves through the file one sample at a time (one-tenth of a

second.)The cursor can also be placed in the graph window by left-clicking the mouse button

at the desired cursor position.

Zoom

Zooming in on the data in the graph or map window can be done three ways.

 Use the left mouse button to click and drag a window from left to right around the

area of interest. Click and drag from right to left to zoom out.

 Use the up and down arrow keys on the keyboard to zoom in around the current

cursor position. Pressing the shift key at the same time makes the zoom happen in

bigger steps.

 If your mouse has a scroll wheel then this can be used to zoom in around the current

cursor position. Pressing the shift key before using the mouse roller ball will make the

zoom occur in bigger steps.

Pan

To pan the view in the graph or map window, put the mouse over the area you wish to pan

then click and hold the right mouse button and move the mouse in the direction that you

wish to pan.

Graph Screen X Axis

To swap the X axis from Time to Distance either press the right mouse button anywhere on

the screen or click the ‘Graph Set-up’ icon, then select ‘Graph Type’, then choose one of the

two options, ‘Speed Against Time’ or ‘Speed Against Distance’.

Speed against distance is useful for overlaying laps with different lap times around the same

circuit (eg. different time, but same distance)

Speed against time is useful for examining performance files (acceleration and deceleration.)
