Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

Intensity Plots

Module by: National Instruments. E-mail the author

You can use intensity graphs and charts to display patterned data, such as temperature patterns and topographical terrain, where the magnitude represents altitude. Like the waveform graph and chart, the intensity graph features a fixed display while the intensity chart features a scrolling display. The intensity graph and chart accept a 2D array of numbers. Each number in the array represents a specific color. The indexes of the elements in the 2D array set the plot locations for the colors. The intensity graph or chart can display up to 256 discrete colors.

Figure 1 shows a 4×3 4 3 array plotted on an intensity graph. The graph transposes the array elements.

Intensity Graph and Chart Options

The intensity graphs and charts share many of the optional parts of the waveform graphs and charts, which you can show or hide by right-clicking the graph or chart and selecting Visible Items from the shortcut menu. In addition, because the intensity graphs and charts include color as a third dimension, a scale similar to a color ramp control defines the range and mappings of values to colors. Figure 2 shows the elements of an intensity graph.

Figure 2 (intensitygraphchart.png)

Use the Operating or Positioning tools to right-click the marker next to the color ramp, select Marker Color from the shortcut menu to change the color associated with a marker, and select the color you want from the color picker that appears. To add markers to a color ramp, right-click the color ramp and select Add Marker from the shortcut menu. To change the value of an arbitrary marker on a color ramp, use the Operating tool to drag the marker to the value you want or use the Labeling tool to highlight the text of the marker and enter a new value.
