6.7.1.1 Selecting Data to be Graphed
Data value(s) are added to a graph by clicking the column heading(s) in the
data panel with a single mouse click. The selection will be highlighted and
will automatically be added to the currently selected graph. (The currently
selected graph is indicated on the main View Pro toolbar, and can be changed
from the drop-down list.)
Multiple columns can be added by holding the Ctrl key and dragging the
mouse pointer over the column headings. A partial column can be added by
dragging the mouse pointer over the desired values. (Note that once a partial
column is selected, it can be extended by holding the Shift key and clicking at
a point below the current selection. The selection will be extended to that
point.) Multiple partial columns can be added by holding the Ctrl key and
dragging the mouse pointer over the desired values.
Data from multiple data files can be displayed in a single graph. This is done
by opening multiple data files and selecting data to be graphed as described
above. This may be useful when comparing data from multiple datalogger
stations.
Creating Multiple Line Graphs
To open an additional Line Graph, select “None” from the Selected Graph
drop-down menu on the main View Pro toolbar. The highlighting in the data
file will be cleared. Select the data that you would like graphed as described
above and then press the Line Graph button. A new Line Graph will be created
with your selection(s) graphed. You may then continue adding selections to the
Line Graph as described above.
An unlimited number of Line Graphs can be opened using this same process.
You can navigate between multiple graphs by clicking on a graph or by
choosing a graph from the Selected Graph drop-down list on the View Pro
toolbar and pressing the Bring the selected graph to the front button.
The highlighted selections in the data files will always indicate
the values being graphed in the currently selected graph NOTE
Deleting Traces from a Graph
A data value can be deleted from a graph by selecting it in the list of values
being graphed (on the left side of the graph window) and then pressing the
Delete button, by right-clicking on this name and choosing Delete Selection,
by left-clicking on the column heading in the data panel, or by right-clicking
on the column in the data panel and choosing Clear Selection.
6.7.1.2 Graph Width
The Graph Width box is used to set the width of a Line Graph either as a
function of time in days, hours, minutes, seconds, and milliseconds or by the
number of records being displayed. If one of these two field is changed, the
other field will automatically change accordingly when the Apply button is
pressed.
