AHELP for ChIPS 4.1

display_axis

Context: sl.chips

Synopsis

Display the specified axis.

Syntax

display_axis();
display_axis( [ChipsId] );
display_axis( "axis_id" );
display_axis( "all" );

Description

Depending on the argument, this command displays the current axis, the axis indicated in a ChipsId structure or by the axis_id, or all axes.

  • (no argument) - the current axis is displayed.
  • ChipsId - an optional ChipsId structure containing values to modify the currency state for the command.
  • axis_id - identification tag given to each object that is created; use this to display a specific axis.
  • all - displays all axes.

Example 1

chips> add_curve([-23,4,15],[10,8,11]);
chips> hide_axis();
chips> display_axis();

Create a curve and hide the axis (or axes), then display the current axis.

Example 2

chips> id = ChipsId();
chips> add_plot(.6, .6, .9, .9);
chips> add_curve([-4,0,4],[0,5,10]);
chips> hide_axis();
chips> add_plot();
chips> add_curve([-4:4],[-4:4]^2);
chips> current_plot("plot1");
chips> id.axis = "ax1";
chips> display_axis(id);

Two plots are created, each containing a curve, and the axes of the first plot are hidden. The id.axis command sets the axis value of the ChipsId structure to the x-axis of the first plot. That axis is then displayed.

Example 3

chips> add_plot(.6, .6, .9, .9);
chips> add_curve([-4,0,4],[0,5,10]);
chips> add_plot();
chips> add_curve([-4:4],[-4:4]^2);
chips> current_plot("all");
chips> hide_axis("all");
chips> display_axis("all");

Two plots are created and both made current. The axes are all hidden, then the display_axis command displays them all.
