AHELP for CIAO 4.9 ChIPS v1

current_axis

Context: axes

Synopsis

Set the specified axis as current.

Syntax

current_axis(id)

Description

The function arguments.

Argument Description
id A ChipsId structure identifying the item, or a string containing the name of the object.

The current_axis command sets the axis indicated by the argument as the current axis; see "ahelp currency" for general information on currency.

Use the info_current command to retrieve a list of all the current items in the ChIPS session, as shown below.

Example 1

chips> id = ChipsId()
chips> add_plot(.6, .6, .9, .9)
chips> add_curve([-4,0,4],[0,5,10])
chips> add_plot()
chips> add_curve(np.arange(-4,4),np.arange(-4,4)*np.arange(-4,4))
chips> current_plot("plot1")
chips> id.axis = "ay1"
chips> current_axis(id)
chips> info_current()

Two plots are created, each containing a curve, then the first plot is set as current. The id.axis command sets the axis value of the ChipsId structure to the y-axis of the first plot, then the current_axis command makes that axis current.

The output of info_current for this session is:

Window [win1]
  Frame [frm1]
    Plot [plot1]
        X Axis [ax1]
        Y Axis [ay1]
        Curve [crv1]
   Coord Sys [Data]
   Coord Sys ID [plot1_ax1ay1]

Example 2

chips> id = ChipsId()
chips> add_plot(.6, .6, .9, .9)
chips> add_curve([-4,0,4],[0,5,10])
chips> add_plot()
chips> add_curve(np.arange(-4,4),np.arange(-4,4)*np.arange(-4,4))
chips> current_plot("plot1")
chips> current_axis("all")

Two plots are created, each containing a curve, then the first plot is set as current. The current_axis command then sets all axes in that plot as current.

Example 3

chips> id = ChipsId()
chips> add_plot(.6, .6, .9, .9)
chips> add_curve([-4,0,4],[0,5,10])
chips> add_plot()
chips> add_curve(np.arange(-4,4),np.arange(-4,4)*np.arange(-4,4))
chips> current_plot("all")
chips> current_axis("all")

Two plots are created, each containing a curve, then all plots are made current. The current_axis command then sets all axes in all plots as current.
