◆ af_grid()

C Interface wrapper for grid setup in a window.

Parameters

[in]	wind	is the window handle
[in]	rows	is number of rows you want to show in a window
[in]	cols	is number of coloumns you want to show in a window

Returns: AF_SUCCESS if grid setup for window is successful, otherwise an appropriate error code is returned.

◆ af_is_window_closed()

C Interface wrapper for checking if window is marked for close.

Parameters

[out]	out	is a boolean which indicates whether window is marked for close. This usually happens when user presses ESC key while the window is in focus.
[in]	wind	is the window handle

Returns: AF_SUCCESS if wind show is successful, otherwise an appropriate error code is returned.

◆ af_set_axes_label_format()

AFAPI af_err af_set_axes_label_format	(	const af_window	wind,
		const char *const	xformat,
		const char *const	yformat,
		const char *const	zformat,
		const af_cell *const	props
	)

C Interface wrapper for setting axes labels formats for charts.

Axes labels use printf style format specifiers. Default specifier for the data displayed as labels is %4.1f. This function lets the user change this label formatting to whichever format that fits their data range and precision.

Parameters

[in]	wind	is the window handle
[in]	xformat	is a printf-style format specifier for x-axis
[in]	yformat	is a printf-style format specifier for y-axis
[in]	zformat	is a printf-style format specifier for z-axis
[in]	props	is structure af_cell that has the properties that are used for the current rendering.

Note: zformat can be NULL in which case ArrayFire understands that the label formats are meant for a 2D chart corresponding to this wind or a specific cell in multi-viewport mode (provided via props argument). A non NULL value to zformat means the label formats belong to a 3D chart.

◆ af_set_axes_limits_2d()

		const float	xmin,
		const float	xmax,

		const float	xmax,
		const float	ymin,
		const float	ymax,

◆ af_set_axes_titles()

AFAPI af_err af_set_axes_titles	(	const af_window	wind,
		const char *const	xtitle,
		const char *const	ytitle,
		const char *const	ztitle,
		const af_cell *const	props
	)

C Interface wrapper for setting axes titles for histogram/plot/surface/vector field.

Passing correct value to ztitle dictates the right behavior when it comes to setting the axes titles appropriately. If the user is targeting a two dimensional chart on the window wind, then the user needs to pass NULL to ztitle so that internal caching mechanism understands this window requires a 2D chart. Any non NULL value passed to ztitle will result in ArrayFire thinking the wind intends to use a 3D chart.

Parameters

[in]	wind	is the window handle
[in]	xtitle	is the name of the x-axis
[in]	ytitle	is the name of the y-axis
[in]	ztitle	is the name of the z-axis
[in]	props	is structure af_cell that has the properties that are used for the current rendering.
