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.)
