I found this question but I couldn't apply it to the example. In the following example, we will draw a scatter plot with 6 (six) data points, and set the colors for the markers with a list of colors, where each color is defined using matplotlib inbuilt color strings.Įxample.py import matplotlib. On the basis of the scatterplot example of matplotlib, how can I change the gray background color of the 3 axes grid planes I would like to set it to white, keeping the grid lines with the default gray color. Note: The length of the colors list that we give for named parameter c, should be consistent with the lengths of x and y. You can also set a global face color for all plots using rcParams. (x, y, s=None, c=None, marker=None, cmap=None, norm=None, vmin=None, vmax=None, alpha=None, linewidths=None, *, edgecolors=None, plotnonfinite=False, data=None, **kwargs) To change the background color of matplotlib plots, you can use the setfacecolor () function of the axes object of the plot. The following is definition of scatter() function with c parameter, at fourth position, whose default value is None. The only parameter required as input is the desired color for. We can specify the color in Hex format, or matplotlib inbuilt color strings, or an integer. The background color of a matplotlib chart can be customized with the setfacecolor function. To change the background color of matplotlib plots, you can use the setfacecolor() function of the axes object of the plot. In this example, we only changed the background color to Orange, and the rest explanation is the same as explained above.To set color for markers in Scatter Plot in Matplotlib, pass required colors for markers as list, to c parameter of scatter() function, where each color is applied to respective data point. In this example we are doing the same thing as in the above example, the only thing we did different from the above example is using “ ax.set_facecolor(“grey”)” to change the background color of graph or figure.Įxample:- 03 import matplotlib.pyplot as plt Finally, in 3 rd example, we draw the graph and change the background color to Orange. It is then sufficient to define the underlying values on the corners of the image and let bicubic. In particular, we use a colormap to generate the actual colors. However, we can emulate a gradient-filled rectangle by an AxesImage of the right size and coloring. Then, we set the size of figure with method “ plt.figure(figsize=(10,6))” where width=10 and height=6 and then we plotted the graph by “ plt.plot(X,Y)“.Įxample:- 02 import matplotlib.pyplot as plt And in 2 nd example, we draw the graph and change the background color to Grey. Matplotlib does not natively support gradients. If any kwargs are supplied, it is assumed you want the grid on and visible will be set to True. The lightness parameter \(L\) can then be used to learn more about how the matplotlib colormaps will be perceived by viewers. In CIELAB, color space is represented by lightness, \(L\) red-green, \(a\) and yellow-blue, \(b\). One way to represent color is using CIELAB. String representation of float value in closed interval 0, 1. Color can be represented in 3D space in various ways. Case-insensitive RGB or RGBA string equivalent hex shorthand of duplicated characters. RGB or RGBA (red, green, blue, alpha) tuple of float values in a closed interval 0, 1. Now, we created the numpy array and stored this in a variable named X and established the relation between X and Y. Parameters: visiblebool or None, optional Whether to show the grid lines. Matplotlib recognizes the following formats to specify a color. In the above example, the background color of the graph is default(White), so first, we need to import two python module “matplotlib” and “numpy” by writing these two lines:.
Finally, in 3 rd example, we draw the graph and change the background color to Orange.Įxample:- 01 import matplotlib.pyplot as plt.And in 2 nd example, we draw the graph and change the background color to Grey.
In 1 st example, we simply draw the graph with the default background color(White).Changing the background color of the graph in Matplotlib with Python Set the Color of a Marker in the Scatterplot import matplotlib. We need to get the axes object before calling the setfacecolor () method. To set the color of markers in Matplotlib, we set the c parameter in () method. Now the last step is to change the background color for the Maplotlib plot. We have to first understand how this work, as there is a method to change the background color of any figure or graph named as “ set_facecolor“. Set Background Color of the Specific Matplotlib Plot. Step 4: Change the Matplollib Background color. we need some basic concepts of two python module named as:-Īctually, we are going to change the background color of any graph or figure in matplotlib with python.
