The diamond_cross() function is a glyph method of the bokeh.plotting.figure module in Python’s Bokeh library. It is used to create a scatter plot of diamond cross glyphs at the specified x and y coordinates.
Here is the syntax for using diamond_cross() function:
diamond_cross(x, y, size=10, angle=0.0, **kwargs)
The parameters for the diamond_cross() function are as follows:
x(required): The x-coordinates of the diamond cross glyphs.y(required): The y-coordinates of the diamond cross glyphs.size(optional, default=10): The size of the diamond cross glyphs.angle(optional, default=0.0): The angle of the diamond cross glyphs, in radians.kwargs(optional): Additional keyword arguments to be passed to the glyph renderer.
Here is an example of using diamond_cross() to create a scatter plot:
from bokeh.plotting import figure, show # create a new plot with specified dimensions p = figure(width=400, height=400) # add diamond cross glyphs to the plot p.diamond_cross([1, 2, 3, 4], [1, 4, 2, 3], size=20, angle=0.3) # show the plot show(p)
This code will create a plot with diamond cross glyphs at the specified coordinates and show it in a new window.
Parameters:
In the diamond_cross() function of the Bokeh library, the following parameters are available:
x(required): The x-coordinates of the diamond cross glyphs.y(required): The y-coordinates of the diamond cross glyphs.size(optional, default=10): The size of the diamond cross glyphs.angle(optional, default=0.0): The angle of the diamond cross glyphs, in radians.**kwargs(optional): Additional keyword arguments to be passed to the glyph renderer.
The x and y parameters are required and specify the coordinates of the diamond cross glyphs. These can be specified as lists, arrays, or other iterable objects containing numerical values.
The size parameter is optional and specifies the size of the diamond cross glyphs. The default size is 10.
The angle parameter is optional and specifies the angle of the diamond cross glyphs in radians. The default angle is 0.0, which corresponds to a horizontal diamond cross.
The **kwargs parameter is optional and allows for additional keyword arguments to be passed to the glyph renderer. These keyword arguments may include properties such as line_color, fill_color, line_width, and alpha, among others, which can be used to customize the appearance of the diamond cross glyphs.
Return:
The diamond_cross() function in the Bokeh library does not return any value. Instead, it adds diamond cross glyphs to a figure object, which can then be displayed using the show() function. The diamond_cross() function modifies the figure object in place, adding glyph renderers to it.
Here is an example:
from bokeh.plotting import figure, show # create a new plot with specified dimensions p = figure(width=400, height=400) # add diamond cross glyphs to the plot p.diamond_cross([1, 2, 3, 4], [1, 4, 2, 3], size=20, angle=0.3) # show the plot show(p)
In this example, the diamond_cross() function is called on the p figure object, adding diamond cross glyphs to it. The show() function is then used to display the figure object in a new window.
Conclusion:
In conclusion, the diamond_cross() function in the Bokeh library is a glyph method that is used to add diamond cross glyphs to a figure object in Python. The function takes in the x and y coordinates of the glyphs, as well as optional parameters such as size and angle, and adds glyph renderers to the figure object. The function does not return any value, but modifies the figure object in place. The appearance of the glyphs can be customized using additional keyword arguments passed to the function.
