Layer Toolbar

The main window may contain the layer toolbar:

From left to right, the toolbar buttons perform the following tasks:

• View coordinate points in the currently active layer. The cursor will change to a crosshair and the data values corresponding to the position of the mouse on the graph will be displayed next to the button.
• View and select data points on the plots in the currently active layer. The cursor will change to a circle with cross hairs.
  • Line plots: When the cursor is clicked when it is over a data point, the values for the point will be displayed next to the button.
  • Contour plots: When the cursor is clicked when it is over a cell, the values for the data at the center of the cell will be displayed next to the button.
• Find the distance between two points. The points are selected by clicking on the graph. The position of the last selected point is shown in the label to the immediate right of the button. When two points have been selected, the distance between them is shown in the rightmost label.
