## iVector Tool Operations

Many operations are available in the iVector tool. Once you have visualized your vector data, you can add streamlines or contours. The following operations are available for vectors.

### Adding and Modifying Streamlines

When a vector visualization is selected, choosing Operations Vector Streamlines will bring up the Streamlines operation dialog:

From this dialog you can control the number of x and y particles, and the number and size of streamline steps. The dialog only contains the properties that directly affect the current streamline data.

After making any desired streamline setting adjustments, select OK to insert a new streamline visualization into the existing dataspace.

The property sheet for the streamline visualization contains additional properties that affect both the streamline data and the visualization. To see the streamline properties, select (with the streamline visualization selected) Edit Properties...

These properties and their values are described in Vector: Visualization Properties.

### Adding Magnitude Contours

When a vector or streamline visualization is selected, choose Operations Vector Contour Magnitude to insert a contour visualization using the magnitudes of the vector data. To modify the contour properties, select (with the contour visualization selected) Edit Properties...

### Adding Direction Contours

When a vector or streamline visualization is selected, choose Operations Vector Contour Direction to insert a contour visualization using the directions of the vector data. To modify the contour properties, select (with the contour visualization selected) Edit Properties...
