The display of the coasts can be toggled on and off with the pull down menu. To change the display attributes of the coasts the user needs to go to the layer manager.
Upon double clicking the coasts icon the following panel will appear.
The linestyle and the line thickness of the coast is set on the left. The current color is shown in the color well. Clicking in the well will bring up the color selection patch.
To change the color of the coasts lines just choose the desired color in the patch and drag it into the well. Please note that no color patch will follow the cursor, only when you release the mouse in the well will the color appear.
As an alternative to removing the coasts is to select the hide radio button. If a layer is hidden it will remain
in the layer manager but will not be plotted.
