# Analysis Tools: Select Poles

The Select Poles option allows you to graphically identify poles on a Pole Plot, by selecting them with the mouse, and automatically highlighting the corresponding row(s) in the spreadsheet.

To use Select Poles:

1. Choose Select Poles from the toolbar or the Tools menu.

NOTE: Select Poles is only enabled if pole vectors are displayed on the stereonet. If pole vectors are not displayed Select Poles will not be available.

2. As you move the cursor over the stereonet, when the cursor is near a pole it will change to a small circle and "snap" to the exact location of the pole.

3. You will notice a popup tooltip which displays the Pole ID and the coordinates of the "snapped to" pole. The Pole ID is the row number of the pole in the grid view (spreadsheet). These numbers are also displayed in the Status Bar at the bottom of the screen.

4. If you click the LEFT mouse button the currently "snapped to" pole will become selected on the pole plot, as indicated by a red square at the pole location, AND the corresponding row(s) of the grid will be highlighted. (If multiple data is at the same location, ALL rows of the grid corresponding to this orientation, will be highlighted).

5. To escape from the Select Poles option, press the Escape key, or right-click and select Cancel.

Selecting Poles on the Grid View

It is useful to note that the Select Poles capability not only works from the Pole Plot to the Grid, but ALSO from the Grid to the Pole Plot. That is, if rows of the grid are selected (by clicking on the row ID buttons at the left of the grid), the corresponding pole(s) on the Pole Plot will be highlighted, in the same manner as when using the Select Poles option described above (i.e. a red square will highlight the selected poles). Experiment with this capability of Dips to see how it works.
