panto

Synopsis

Change the location of the center of the plot.

panto(x, y)
panto(id, x, y)

Description

The function arguments.

The panto command changes the plot so that it is centered on the supplied coordinates.

Related commands

The pick_limits(), limits(), and zoom() commands can also be used to change the limits of the plot, and they can also be changed directly using the ChIPS GUI.

Examples

Example 1

chips> x = np.arange(0,10,0.1)
chips> y = np.tan(x)
chips> add_curve(x, y, ["symbol.style", "none"])
chips> limits(0, 10, -40, 90)
chips> get_plot_range()
[0.0, 10.0, -40.0, 90.0]
chips> panto(6, 0)
[1.0, 11.0, -65.0, 65.0]

Here we create a plot, set the limits and then use the panto command to change the center of the plot. The final plot still has a data range of 10 (x) and 130 (y).

Example 2

chips> clear()
chips> add_image("img.fits", ["colorbar", "heat"])
chips> panto(230.0414, -42.4876)
chips> zoom(2)

Here we display an image, change it so that it is centered on a new location and then zoom into the plot.

Example 3

chips> pv = get_pick()
chips> panto(pv[0][0], pv[1][0])

Here we select a point on the plot using the mouse and then use panto() to change the plot to center on this location.

Example 4

chips> id = ChipsId()
chips> id.plot = "plot1"
chips> panto(id, 100.324, 84.56)

Here we change the center of the plot called "plot1". This is similar to

chips> current_plot("plot1")
chips> panto(100.324, 84.56)

except that the latter requires a call of "undo(2)" to revert.
