The Axis Options dialog allows you to select which column is plotted and how it is scaled.
Scaling
The scaling options control how the limits of the graph are set. There are five scaling options available:
Autoscale Larger (Default): Similar to Autoscale except the
graph
limits will never be made smaller.
Autoscale: The software will choose an appropriate range for
the axes, based on the data being plotted.
Autoscale From 0: Similar to Autoscale except that one of the
endpoints
of the axes will be at zero and the other will be set based on the data
range.
Manual: In this mode, you can choose both endpoints of the axis.
Enter the minimum and maximum values to plot in the text boxes under
this
option.
Right: Manually enter the
maximum value you wish to show on your graph (disabled if autoscaling
is
chosen).
Left: Manually enter the
minimum value you wish to show on your graph (disabled if autoscaling
is
chosen).
Strip Chart (X-Axis
only): Each
new data point gets added on the rightmost edge of the chart during
data collection, and older points scroll off the left edge. The width
of the graph in data points is set in the Axis Options Tab. This mode
mimics a paper strip chart recorder.
You can rotate the X-Axis tick
labels (numbers or names) for easier viewing. This is useful
when the labels are long and require extra space. The default tick
labels along the X-Axis are horizontal (zero degrees).
Zero Degrees
(default)
Forty-five Degrees
To quickly change the axis range, click on an end point value of the axis in the graph window. A box will appear allowing you to enter a new value.
Note: You can reverse the direction of the X or Y-Axis so
that
the right or top number is less than the left or bottom number. For
example, a graph might run from 3 (bottom of graph) to 2 (top of the
graph). If you set a reversed axis range as mentioned above and
the axis scale is set to manual, it will stay that way. Zooming and
unzooming
preserve the data direction. If you set a reversed axis range as
mentioned
above and Autoscale, the reversal is not preserved. Autoscale always
uses
the standard direction of data (min is min and max is max). If a
column's
data are all negative, and Autoscale-from-zero is set for the axis, the
axis maximum will be set to zero.
