Position an Axis at a specific data value in Grapher
By default, Grapher places intersecting X and Y axes at the bottom left corner of the graph with Y axis values ascending, and increasing X values displayed toward the right. But your axes can be positioned anywhere on the page. You can also move your axes so that they are relatively positioned to each other.
Setting the axis position
Use the File | Open or Home | New Graph command to load or create your graph. The graph is displayed with the axes in their default locations.
To move the X axis so that it crosses the Y axis at the zero value:
- Click on X Axis 1 in the Object Manager to select it.
- In the Property Manager, click on the Axis tab.
- Click the Set button in the Position field.
- In the dialog, select At data value of... and make sure the value is 0.0.
- Click OK.
The X axis now crosses the Y axis at Y=0.
To move the Y axis so that it crosses the X axis at the zero value:
- Click on the Y Axis 1 in the Object Manager to select it.
- In the Property Manager, click on the Axis tab.
- Click the Set button in the Position field.
- In the dialog, select At data value of... and make sure the value is 0.0. Change the Move option so that X Only is selected. This will move the Y axis to the right, but not up/down.
- Set the position to At data value of... and select to Move in the X Only direction.
- Click OK.
The axes now cross each other at the zero values.
Once both axes are moved, the axes cross each other at the X=0 and Y=0 locations.
If the axis limits change, the axes will need to be reset to these locations again by following the steps above.
