Plot Title Resolution For Free

To add a title to a collection of Pandas histogram plots, we can use the suptitle function. This function adds a title to the entire figure, rather than to individual subplots. In this code, we added the fig. suptitle function to add a title to the entire figure.

The Matplotlib title() function is used to specify titles to the 2D graphs plotted using matplotlib. pyplot. The title() function can also be used to change the color, size, font, alignment, etc., of the title.

We'll use NumPy to generate some data and Matplotlib to plot it: x = np. linspace(0, 10, 100) y = np. sin(x) plt. plot(x, y) plt. show() plt. figure(dpi=300) plt. plot(x, y) plt. show() plt. figure(dpi=300) plt. plot(x, y) plt. savefig('high_res_plot.png', dpi=300)

To set title for plot in matplotlib, call title() function on the matplotlib. pyplot object and pass required title name as argument for the title() function. The following code snippet sets the title of the plot to ?Sample Title?.

Setting a title for just one plot is easy using the title() method. By using this function only the individual title plots can be set but not a single title for all subplots. Hence, to set a single main title for all subplots, suptitle() method is used.

Choose a resolution between 300 and 600 dpi ? Effective resolutions below 300 dpi (dots/pixels per inch) often result in a blurry, jagged or pixelated image that is not optimal to publish, and resolutions above 600 dpi frequently must be resized or rescaled.

To change the image's resolution in matplotlib, we have to change the value of the key 'savefig. dpi' in the matplotlibrc file. The above syntax will change the dpi of the image to 300.

By default, Matplotlib renders images at 100 dpi (dots per inch) where 1 dot is one pixel so the above image is 585 x 413 pixels in size (corresponding to an A6 image's dimensions of 5.85 x 4.13 inches) when run in Python.

To change the image's resolution in matplotlib, we have to change the value of the key 'savefig. dpi' in the matplotlibrc file. The above syntax will change the dpi of the image to 300.

Use the title() function title() can be also used to add titles to a graph. A simplified format is : title(main = NULL, sub = NULL, xlab = NULL, ylab = NULL, ...)
