set_data_aspect_ratio

Context: plots

Synopsis

Set or retrieve the aspect ratio information of the data.

Syntax

set_data_aspect_ratio([id], ratio)
get_data_aspect_ratio([id])

Description

The function arguments.

Argument Description
id A ChipsId structure identifying the item.
ratio The new aspect ratio for the plot, as a string. The format should be "a:b" - where a and b are numbers - or the empty string "". Unlike set_plot_aspect_ratio, "fit" and "current" can not be used.

The set_data_aspect_ratio command is used to change the aspect ratio of the data. The ratio is specified as "a:b". If set_data_aspect_ratio is called without specifying a ratio, the data aspect ratio is disabled.

The get_data_aspect commands return the aspect ratio of the specified data.

"ratio" option values

Value Description
"a:b" Explicitly set the aspect ratio, e.g. "2:1".
"" Turn off the aspect ratio. Using this option expands the aspect ratio back to the area defined by the plot margins.

For more information on aspect ratios, refer to "ahelp aspectratio".

Example

chips> z = np.arange(10)
chips> add_curve(z,z-4,[z*0.2,z*0.1])
chips> set_data_aspect_ratio("1:1");

Plot a line, then set the data aspect ratio to "1:1".
