Firstly, you have to know how to create a pie chart. Here we learn how we can save the pie chart as an image. Read: Matplotlib dashed line Matplotlib save chart as png After that use show() method which is used to generate a plot for the user in a window.Once the plot is generated, we use the savefig() method to save figures in our projects directory.plot() function is used to plot a graph.After this, we define data in x and y coordinates. In the above example, firstly we import matplotlib.pyplot library.Let’s see an example of save as png: # Import Library metadata: specifies key/value pair to store in the image metadata.pand_inches: specifies padding around the image when bbox_inches is “tight”.bbox_inches: specifies the portion of the image to save.transparent: to make the background of the image transparent.format: specifies the extension of the file such as.papertype: specifies the type of paper such as “letter”, “legal” “a0 to a10”, etc.orientation: You can set the orientation of the image as Landscape or Portrait.
edgecolor: specifies edgecolor of the plot as per your choice.facecolor: specifies facecolor of the image as per your choice.fname: specifies file name or file location.The parameters used are discussed as below: The syntax of the savefig() method is as below: (fname, dpi=None, facecolor='w', edgecolor='w', orientation='portrait', papertype=None, format=None, transparent=False, bbox_inches=None, pad_inches=0.1, frameon=None, metadata=None) The objective of this method is to save images to your local system memory. To save a plot or graph or a figure as png we use the savefig() method. Note: Use savefig() method before show() method. Generate Plot: By suing show() function, generate a plot to the user.Set extension of the file to “png” as your main aim is to save as png. Save as png: By using savefig() method you can save image into your system.Create a pLot: By using plot() method create a plot or you can use any other method which ever you like.Define X and Y: Define the data values used for the x-axis and y-axis.Defining Libraries: Import the important libraries which are required to save image as png and to define data (For data creation and manipulation: Numpy, For data visualization: pyplot from matplotlib).The following steps are used to save plot or graph as png are outlined below: PNG is a compressor used to compressed images into smaller sizes without losing their details. Firstly, we discuss what does “png” mean:
In this section, we are going to learn about how we save a plot or graph as an image file by using the matplotlib library. Matplotlib save as png edgecolor Matplotlib how to save as png
