Synopsis
Reverses the direction of one or more axes.
Syntax
reverse_axes() reverse_axes(dimension) reverse_axes(id) reverse_axes(id, dimension)
Description
The function arguments.
| Argument | Description |
|---|---|
| dimension | One of X_AXIS, Y_AXIS, or XY_AXIS to specify the X axis, Y axis, or both. |
| id | A ChipsId structure identifying the item. |
The reverse_axes command modifies the plot display so that the specified axis and all corresponding data are transposed. That is, data that increases to the right will increase to the left and vice-versa. Reversing the axis a second time returns the axis display to its original setting. All objects within a data system defined by a reversed axis are modified as appropriate.
Reversing axes does not change currency of the axes within a plot, but may change the currency of the plot, frame, or window being accessed.
Examples
Example 1
chips> reverse_axes()
Reverse the x and y axes, as well as all objects in the associated data systems.
Example 2
chips> add_axis(X_AXIS, 1, 1, 10)
chips> add_axis(X_AXIS, 0, 1, 10)
chips> add_axis(Y_AXIS, 0, 1, 10)
chips> x = np.arange(-4, 4)
chips> add_curve(x, x**2)
chips> current_axis("ax1")
chips> add_line(1, 9, 10, 16, "color=coral")
chips> id = ChipsId()
chips> id.axis = "ax2"
chips> reverse_axes(id, X_AXIS)Create a plot containing two x-axes, then add a curve in the coordinate system of the second x-axis and a line in the coordinate system of the first. Use a ChipsId structure to reverse the second x-axis.
