AHELP for CIAO 4.9 ChIPS v1

lin_scale

Context: axes

Synopsis

Changes the plot axis to use a linear scale.

Syntax

lin_scale()
lin_scale(dimension)
lin_scale(plotname)
lin_scale(plotname, dimension)
lin_scale(id)
lin_scale(id, dimension)

The function is also available as linear_scale().

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.
plotname The name of the plot to modify, as a string.
id A ChipsId structure identifying the item.

The lin_scale command changes the given axis (or axes) to use a linear scale. To change back to a logarithmic scale use the log_scale command.

When the scale of an axis is changed, any axes that are bound to that axis are also changed, including plot border axes; see the bind_axes command for more information.

Example 1

chips> lin_scale()

Set the current X and Y axis to linear scale.

Example 2

chips> lin_scale(X_AXIS)

Set the current X axis to linear scale.

Example 3

chips> lin_scale("plot1")

These commands change the X and Y axes of the plot called "plot1" to a linear scale.

Example 4

chips> id = ChipsId()
chips> id.plot = "plot1"
chips> lin_scale(id)

An alternative means to change the scaling of the axes in plot "plot1". This method is the only way to directly change a plot that is not in the current frame: for example

chips> id.window = "win2"
chips> id.plot = "plot2"
chips> lin_scale(id, Y_AXIS)

will change the Y axis of the plot called "plot2" in window "win2" to be drawn with a linear scale.
