The Tools Panel is the oval panel to the left of the graph, it contains
all the essential tools specific to the open graph file. It contains the
Their functions are as follows;
Selection boxes allow you to define a specific area for which you wish
to analyse or manipulate the data. When Selection cursor is highlighted,
Selection boxes can be created by clicking and dragging corner to corner
with the mouse button still depressed, the box is defined when the button
is released. Click once in an open graph space to cancel a selection box.
The Select cursor tool also lets you determine specific graph point coordinates
(by placing the cursor over them and reading the output in the coordinate
boxes, see below) and edit or remove pre-placed Text Labels.
Zoom lets you see the data in more detail in a specific area. With Zoom
highlighted, You can zoom by clicking on the area you wish to see in more
detail, clicking again will Zoom further and so on. A Zoom box can be
created by clicking and dragging corner to corner with the mouse button
still depressed, the box is defined when the button is released. To return
to the graphs original state click once on the Zoom icon in the Tools
Measure lets you know the change in 'y' over a specific 'x' interval either
within a graph channel or between two different channels. Highlight Measure,
then select your two points by clicking once on a graph channel for each,
as you do this a dashed line will appear to illustrate the distance from
the first point, (the default is the change within one channel, this can
be changed at the next step). After the second click a Measure window
will appear, this displays your chosen 'x' interval (which can be modified)
the channel you selected and the resultant change in 'y', the rate 'y/x'
is also displayed. Two options are present - the default 'Within Channel,'
displaying the change in that channel over the interval and 'Between Channels'
showing the change between two - both have dropdown lists to select the
Text Label allows you to make a note and attach it to a specific channel
at your chosen point. Select Text Label and the Label window will appear.
Firstly select the channel you wish to apply it to from the dropdown list,
then place the text you wish to appear in the caption box, next click
on 'place,' the window closes allowing you to select placement of the
ledger point upon first click and text position upon second (the text
is connected to the point by a ledger line). The Text Label window also
allows you to temporarily remove all labels by clicking 'Hide All' and
permanently remove labels by clicking 'Delete'. The Label window can be
accessed for editing, deleting or placing existing text by double clicking
the specific text when Selection cursor is highlighted.
The Channels list can be found under the tools in the Tools Panel. Channels
represent specific sensors or data sets. A button to the left of each
Channel title allows you to turn that Channel on or off, if the Channel
is off it will appear greyed and the corresponding data will not be visible
in the Time Graph window. When a Channel is on the button appears the
same colour as the corresponding data in the Time Graph window. The colour
for a Channel may be defined from a palette that appears upon double clicking
the Channel button. The Channel title may be edited by double clicking
it. There is a maximum of eight Channels to work with.
At the bottom of the Tools Panel there are two coordinate boxes labelled
'x' and 'y' these allow you to view the specific coordinates of a Channel
as the Selection cursor moves over them. The colour of the numbers corresponds
to the Channel they are reading. These boxes also display the changing
'x' and 'y' coordinates between two points when the Measure tool is highlighted.
