Raise the Dimension On/Off/Reorder Dialog to enable you to manipulate dimensions, such as to turn on, turn off some of the dimensions, or reorder the dimensions.
Check the "On" field after a dimension name to turn the dimension on.
Uncheck the "On" field after a dimension name to turn the dimension off.
Click the "<-" button after a dimension name to increase the dimension's order. If it is already the first dimesion, it will become the last one.
Click the "->" button after a dimension name to decrease the dimension's order. If it is already the last one, it will become the first one.
When a dimension is turned off, you will not see it from the displays.
You can change the order of the dimensions to change the adjacent relationships of the dimensions.
When there are too many fields to fit in this dialog, use the horizontal and vertical scrolling bars to see rest of the fields.
Function:
Various parameters and thresholds can be set by the user to better control the reordering process. Dimension reordering dialog box allows you to set the parameters for reordering dimensions according to two criteria: dimension similarities or visual clutter.
Operations:
In this Dimension Reorder dialog box, the user should first specify whether to reorder the dimensions using a similarity measure or a clutter measure.
1) Similarity-Based Dimension Reordering Parameters
Each similarity measure reveals dimension relationships in a different way.
2. Clutter-Based Dimension Reordering Parameters
3. General Reordering Parameters
Reordering Algorithms allow the user to use four different algorithms to search for a desired dimension order.
Tips:
The definitions of thresholds in the Clutter Based Dimension Reordering are:
Raise the Dimension Reduction Dialog so that you can reduce the dimensionality of the display using the Visual Hierarchical Dimension Reduction (VHDR). Please refer to the help page of Dimension Reduction.
Raise the Data Summary & Statistics Dialog to provide you the data summary and statistics information of the current data set.
Raise the Glyph Placement for Flat Display Dialog. You can change the glyph placement mode for flat displays.
There are four different glyph placement modes in XmdvTool:
Original - Glyphs are placed from left to right, then up to down, according to their order in the *.okc file.
Ordered - Glyphs are placed from left to right, then up to down, according to their values in one dimension (base dimension).
Data_driven - Glyphs are plotted in the display according to their values in two dimensions (X dimension and Y dimension).
Derived - Glyphs are plotted in the display according to two of their principal components or dimensions values.
To select the Original mode, check the "original" radio button on the top of the dialog, then click the "Apply" button at the bottom.
To select the Ordered mode:
Check the "ordered" radio button on the top of the dialog.
Click one of the dimensions listed in the list box as the base dimension.
Check the "increase" check button for an increasing order. Uncheck it for an decreasing order.
If you check the "space" check button, the distance between two adjacent glyphs will be proportional to the difference of their value in the base dimension.
Click the "Apply" button at the bottom.
.
To select the Data_driven mode:
Check the "data_driven" radio button on the top of the dialog.
Click one of the dimensions listed in the list box as the X dimension. Click the "Select X" button to make it to appear in the entry after the button.
Click one of the dimensions listed in the list box as the Y dimension. Click the "Select Y" button to make it to appear in the entry after the button.
If you check the "reduce overlap" check button, the overlapped glyphs will be separated a little bit..
Click the "Apply" button at the bottom.
.
To select the Derived mode:
Check the "derived" radio button on the top of the dialog.
Click one of the principal components or dimensions listed in the list box as the X dimension. Click the "Select X" button to make it to appear in the entry after the button. Principal_Component_0, Principal_Component_1, Principal_Component_2, are the first, second, and third principal components of the data set.
Click one of the principal components or dimensions listed in the list box as the Y dimension. Click the "Select Y" button to make it to appear in the entry after the button.
If you check the "reduce overlap" check button, the overlapped glyphs will be separated a little bit.
Click the "Apply" button at the bottom.
You can see the change of glyph placement immediately after you click the "Apply" button.
Function:
The Time Series Animation dialog box allows users to set the parameters and control time series animation.
Operation:
1) Selecting Time Dimension:
Time series animation displays the records according the order of one dimension. Time dimension widgets allow users select a dimension. Select a dimension in the combo box, and then click the “Select Time Dimension” button, that dimension will become time dimension.
Figure 1: Time Dimension Dialog
2) Setting Time Window Width:
Time window width controls window size, and only records that fall in this window will be shown. Users can move the slide bar to select time window width.
3) Setting Current Time:
While animation is playing, current time widget shows the center of displayed records.
4) Manual Option:
When manual is checked, users can move the Current Time manually and watch the selected records.
5) Selecting Style:
Select a style for animation color. Four styles are available: “Green->Yellow”, “Fade out”, “Red-Blue”, “Red->Blue, Fade out”.
6) Animation:
Click this button, the animation will be played.
