# Insert a dot

Wizard to insert a dot into the tactile graph. You must enter the coordinates of the dot:

- X: Horizontal coordinate of the dot. The value can be from 0 up to the width of the touch graph (-1). The value 0 is positioned to the far left, while higher values move the point to the right, up to the maximum width;

- Y: Vertical coordinate of the dot. The value can be from 0 up to the height of the touch graph (-1). The value 0 is positioned at the top of the graph, while upper values move the point towards the bottom, up to the maximum height.

In geometry the point is a coordinate, a simple position without dimensions. This primitive concept is considered in the other vector instructions, which use the point to indicate positions for tracing geometric figures. Instead, using this wizard or writing the instruction directly, the point takes on the value of a geometric figure, and then produces a point in the tactile graph.
