How do I add grid lines at the major or minor tick positions?
The majortick.grid and minortick.grid sections of the axis attribute settings control the appearance of grid lines:
chips> get_xaxis().majorgrid color = default style = 6 thickness = 1.0 visible = False chips> get_xaxis().minorgrid color = default style = 2 thickness = 1.0 visible = False
The set_axis set of commands can be used to show, or hide, the grids. In the following we turn on just the major grid and then both grids for both axes; if set_xaxis or set_yaxis had been used then this would have been limited to the X or Y axis respectively.
chips> set_axis(["majortick.visible", True]) chips> set_axis(["majortick.visible", True, "minortick.visible", True])
Here are two examples taken from the ChIPS gallery:
The ChIPS GUI
The ChIPS GUI makes it easy to modify a visualization using your mouse, rather than Pythoon functions. New in CIAO 4.5 is the ability to add annotations - such as labels, lines, points and regions - directly from the GUI.
