Graph Menu

Graph Tools Cursor

Floating Cursor, when checked, will display a crosshair type cursor that
you can move with the mouse. You can use the Floating Cursor to pinpoint
a particular temperature and time. The status bar displays the data point
number, the time, and the temperature, where the crosshairs meet.

Tracking Cursor, when checked, will perform similarly to the Floating Cursor,
except that it will lock on to the plot line. With this option enabled, you
can move the mouse left and right without regard to up and down, and the
horizontal cursor will remain pointing to the plot line.

Software

Data (Box) Zoom, when checked, allows you to use the mouse to click and drag
a rectangle around a line of data to magnify that portion of the chart. The chart
size will remain the same, but the axes will be expanded as well and the data
line(s) to allow viewing more detail. Click and drag the left mouse button to
the right and downwards. A bluish translucent rectangle will appear showing
the area that will be displayed when the mouse button is released. Note that
moving the mouse in the opposite direction Zooms Out. To cancel data zoom
select “Reset Axes” from either the context menu or Graph menu options.

Zoom allows you to change the overall zoom factor of the chart. This is
achieved by clicking the left mouse button anywhere on the chart and
dragging the mouse. Dragging the mouse toward the bottom of the chart area
zooms out while dragging toward the top zooms in. If you have a wheel mouse
you can zoom in/out by clicking on the chart then use the wheel to zoom in/
out.

Configure

The Configure Axes menu allows you to adjust the viewable range of
temperatures to suit your particular application. The narrower the range
between minimum and maximum, the more detail can be seen on the chart.

The Graph Area menu allows you to change the color and/or style of the chart
background, lines and markers.

The Show Gridlines option displays or hides gridlines on the graph.

The Show Markers option displays or hides data point markers on the plotted
data line.

Cancel Zoom will cancel and uncheck Data (Box Zoom) or Zoom if either is
enabled.

Reset Axes returns the graph to its original size.

Data Menu

The Auto Fit Columns menu option resizes the columns to the smallest size
necessary to fit all the data in the columns.

The Auto Scroll menu option causes the data to be scrolled up one line each
time a new row of data is added to the grid.
