Viewing and Profiling Matrix Data

Contents

Viewing Matrix Data

Data contained in a matrix object can be viewed as an image right within the matrix window. To switch from data view to image view, use the View: Image Mode menu item, with the matrix object active. One could thus perform computations and generate a matrix with data and then switch the view to image mode to view the data as an image. The view can be toggled between data and image using the menu item mentioned above.

Data in a matrix can also be plotted as an Image Plot. This displays the data as a 2D plot where each cell is represented as a "pixel" in the graph. Please refer to Appendix 2: Graph Types: Image: Image Plot for further information.

Profiling Matrix Data

Data in a matrix can be profiled. In other words, you can the get vertical or horizontal profiles of the data.

To use this function:

  1. Activate the matrix containing the data to be profiled.
  2. Select Plot: Image: Image Profiles or Plot: Contour: Contour Profiles from the Origin menu to open the Image Profiles dialog box, which is shown below:
    Image:profiles1.png
  3. Customize the settings in the dialog, for example choose a desired layout mode and add profile lines.
  4. Drag the profile lines to the desired positions.

For more information about Image Profiles and Contour Profiles, please refer to Appendix 2: Graph Types: Image: Profiles and Appendix 2: Graph Types: Contour Graphs: profile2.

Controls in the Dialog

Image:Delete_graph.png

Specify whether to delete the profile graphs and data after the Image Profile dialog is closed.

Image:crossed lines.png

Arrange the profile plots and the source plot in the same graph. Both vertical and horizontal profile lines can be used in this case.

Image:vertical line.png

Arrange the profile plots and the source plot in the same graph. However, only vertical profile lines can be used.

Image:horizontal line.png

Arrange the profile plots and the source plot in the same graph. However, only horizontal profile lines can be used.

Image:seperate.png

Plot the vertical and horizontal profile plots in separate graphs.

Image:add vertical line.png

Add a vertical profile line.

Image:add horizontal line.png

Add a horizontal profile line.

Image:activate output.png

This button is enabled only when the profile plots are in separate graphs. When this button is clicked, the profile graph that corresponds to the active tab will become active .

Image:duplicate profile.png

Duplicate the active profile.

Image:delete profiles.png

Delete the active profile.

Operations on the Tabs

You can rename the tabs by right-clicking on the tab title and then choosing Rename from the shortcut menu.

Controls on the Tabs

Color

Specify the color of profile lines.

Width

Specify the width of profile lines.

  • By pixel
    Select this radio button if you want to specify the width of the profile line in pixels. The Pixels edit box becomes available for you to enter the width.
  • By scale
    Select this radio button if you prefer to specify the width of the profile line by scale. Then the Scale edit box can be used to specify the width.
Pixels
This edit box is editable only when by Pixel is selected. Use it to specify the width of the profile line. The unit is one pixel in the data matrix.
Scale
This edit box is editable only when by Scale is selected. Use it to specify the width of the profile line. The unit is the scale of the data matrix.
X

Specify the position of the profile. This is available only when the profile is a vertical one.

Y

Specify the position of the profile. This is available only when the profile is a horizontal one.

Text Location

A text label is displayed on the axis to show the position of the profile. Using the drop-down list, you can specify the position of this text label. Available options:

  • Top
    On the top axis. (This is for vertical profiles.)
  • Bottom
    On the bottom axis. (This is for vertical profiles.)
  • Left
    On the left axis. (This is for horizontal profiles.)
  • Right
    On the right axis. (This is for horizontal profiles.)
