National Instruments 374318A-01 Cursor Operations, Annotation Operations

Chapter 2 Measurement Studio Measurement Computing Edition .NET Class Libraries

• 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.

• Create custom point and line styles for plots.

• Specify anti-aliased plots for plot lines.

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, exact autoscaling, loose

autoscaling, 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.

Cursor Operations

• Use cursors to identify key points in plots and the plot area.

• Configure cursor snap modes to be floating, nearest point, or to plot.

• Use cursor labels to display X and Y data coordinates that the cursor

crosshair points to, and customize the text font and colors of the label.

• Create custom point and line styles for cursors.

Annotation Operations

• Configure text labels, arrows, and drawing shapes to annotate a point

anywhere in the plot area of the graph.

• Configure range area, text labels, and arrows to annotate a range in the

plot area of the graph.

Additional Operations

• Zoom interactively.

• Specify the image format of the control as BMP, GIF, JPEG, or PNG.

• Configure major, minor, and custom divisions and origin lines.
