Measurement Studio User Manual
With the waveform graph and scatter graph controls and the classes that
interface with the controls, you can perform the following operations:
Plot Operations
•
Plot and chart arrays of double-precision floating point values, analog
waveforms, and complex waveforms.
•
Configure a graph to contain multiple plots to show separate but
related data on the same graph.
•
Draw lines or fills from a plot to an X value, Y value, or another plot.
•
Specify plots in the scatter graph control as X and Y data. Specify plots
in the waveform graph control as X or Y data and optionally with date
and time scaling.
•
Use the extensible plot and plot area drawing capabilities and events to
customize the graph appearance.
•
Use plot data tooltips to display X and Y coordinates when a user
hovers the mouse over a data point.
•
Create custom point and line styles for plots.
•
Specify anti-aliased plots for plot lines.
•
Calculate and display error bands.
Axis Operations
•
Configure a graph to include multiple axes or independent ranges so
that plot data fits the graph plot area.
•
Configure the axis modes to: fixed; autoscaling, including autoscaling
based on the visible data only; strip chart; or scope chart.
•
Use logarithmic axes with configurable bases.
•
Interactively change the range of an axis and invert the axis at run time
by clicking on the axis end labels.
•
Display origin lines.
•
Display captions on the axis.
•
Display grid lines.
•
Position the axis to display on one or both sides of the graph’s plot
area.
•
Configure major, minor, and custom divisions and origin lines.
