Working with the DWO » The graph-draw-tool

The graph-draw-tool looks like this.
whole graph-draw-tool
If the graph-draw-tool is underneath a coordinate system, you can plot graphs yourself.

The buttons have the following functions:
button with a pencil Plot points in the coordinate system.
button with an eraser Remove points from the coordinate system.
button with a mouse pointer Move points in the coordinate system.

button with dots Show only points (no graph)
button with line through dots Plots a straight line from point to point.
button with smooth line Plots a smooth line through the points.
button with smooth line and extrapolation Plots a smooth line through the points which is extrapolated.

drop-down list You can select Graph 2 and Graph 3 with this drop-down list. This way you can plot (or change) a green (Graph 2) and a red (Graph 3) graph.

button with refresh symbol Deletes everything of the colour which is selected with the drop-down list drop-down list from the coordinate system.
On a tablet this often works faster than using the eraser or mouse pointer to change the graph!
