The operation process of hiding the scale value of the geometric sketchpad coordinate axis

The first thing to understand is:

In the coordinate system that comes with the system, the scale value on the number axis can only be enlarged or reduced, but cannot be hidden. Only when using a custom coordinate system, such as the ant coordinate system, can the scale values ​​on the coordinate axis be hidden. The specific operations are as follows:

Step 1 to establish the ant coordinate system

1. Open the geometric sketchpad, press and hold the [Custom Tool] on the left toolbar, and select [Classic] in the pop-up shortcut option Coordinate system]——[Ant | Cartesian coordinate system (no parameter version)], as shown in the figure.

2. After selecting the ant coordinate system tool, click twice on the blank space of the drawing board. The ant coordinate system tool will appear, including the coordinate system, console and coordinate system control buttons, as shown in the figure Show.

3. Click [Move Arrow Tool], then use the mouse to click the [System Initialization] button in the coordinate system menu on the screen to restore the coordinate system to its initialized state.

Step 2 Hide the scale value of the coordinate axis

After establishing the ant coordinate system, we can see that there is a control panel on the right side, which contains many of the coordinates System control button, just select [Move Tool] and click the [Hide Scale Value] button with the mouse to hide the scale value of the coordinate axis. The operation is very convenient.

The control panel on the left also includes [System Initialization], [Show Grid Lines], [Hide Tick Marks], [XY Unit Length], [Switch to Number Axis] ], [Restore Coordinate System], [Change Scale Font], [Operation Console] and other control buttons. Use these buttons to adjust the coordinate system.
