Viewing and Profiling Matrix Data
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 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:
- Activate the matrix containing the data to be profiled.
- 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:
- Customize the settings in the dialog, for example choose a desired layout mode and add profile lines.
- 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
|
Specify whether to delete the profile graphs and data after the Image Profile dialog is closed.
|
|
Arrange the profile plots and the source plot in the same graph. Both vertical and horizontal profile lines can be used in this case.
|
|
Arrange the profile plots and the source plot in the same graph. However, only vertical profile lines can be used.
|
|
Arrange the profile plots and the source plot in the same graph. However, only horizontal profile lines can be used.
|
|
Plot the vertical and horizontal profile plots in separate graphs.
|
|
Add a vertical profile line.
|
|
Add a horizontal profile line.
|
|
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 .
|
|
Duplicate the active profile.
|
|
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.)
