Chapter 2 Measurement Studio .NET Class Libraries

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.
