When you plot a graph, the default parameters for the figure size the 6.4×4.8 inches. Changing figure size using figsize argument There are a number of ways in which you can change the size of the figure. But sometimes, we may need to change the size of this figure. It fits perfectly on a standard computer screen. This size is standard for any graph produced by the matplotlib library. That means it has a height of 4.8 inches and a width of 6.4 inches. The size of this graph produced using the matplotlib.pyplot module has a default size of 6.4×4.8 inches. Well, we can clearly understand that Python was invented in 1991 seeing this, so yeah, we did it. We can make a beautiful and simple scatter plot. Scatter Plot Programming Language Foundation Year In the end, we used the plt.show() method to display the actual graph. Then we set the title and labels of the axes. We passed programming language as the X-axis and Foundation year as the Y-axis. After that, plot the scatter plot using () which takes 2 arguments – the X-axis and the Y-axis. First, we read the CSV file and store the data in a dataframe using the pandas library. To plot the graph, we’re going to use the pyplot module of the Matplotlib library. Plt.title("Programming language-Foundation year scatter plot") If you don’t know how to create a dataframe, make sure to check out this article where we learn to create a dataframe. We’re going to create the scatter plot based on a dataframe that we created in one of the previous articles. Let’s try to create a scatter plot using Matplotlib. It’s very common, well-known, and really powerful. Plotting a simple scatter plot using MatplotlibĪ scatter plot is a simplistic 2-dimensional graph. On our way, we’re going to check different ways in which you can change the size of figures drawn with matplotlib. In this article, we’re going to dive deep into the world of data science and explore the matplotlib library. There are many ways in which you can achieve this. An important feature is its ability to change the figure size. It allows you to control every aspect of the visual you create. The Matplotlib library provides a lot of flexibility in creating graphs and designs. Along with numPy, Pandas, SciPy, and many more, it lays down the basis of data science in the most easiest way possible. And at the heart of it stands Matplotlib, an amazing library for creating all kinds of visuals of the data. Return fig, np.flip(np.asarray(list(axes)).One of the key fields where Python shines is Data Science, with no other language there that stands out like Python. Inner_ax_height = axis_height / figheight V_margin = (figheight - (nrows * axis_height)) / figheight / nrows / 2 # spacing on each top and bottom of the figure H_margin = (figwidth - (ncols * axis_width)) / figwidth / ncols / 2 # spacing on each left and right side of the figure Within the grid defined by nrows, ncols, and figsize.Īllows you to share y and x axes, if desired. Spaces axes as far from each other and the figure edges as possible Sharex: bool=False, sharey: bool=False) -> Tuple: The arguments include absolute height and width for the figure (see the matplotlib documentation for details) and absolute height and width for the axes, as requested in the original question. It centers the axes inside their grid areas, giving them as much space as possible between themselves and the edges of the figure, assuming you set figsize large enough. I created a function that creates axes with absolute sizes and acts in most ways like plt.subplots(.), for example by allowing shared y- or x-axes and returning the axes as a shaped numpy array. Plt.savefig(f'-subplots.pdf', bbox_inches='tight', pad_inches=0) If I make the height of the resulting PDFs the same (and thus the axes), the font on 3-subplots.pdf is smaller than that of 2-subplots.pdf.įig, ax = plt.subplots(1, cols, sharey=True, subplot_kw=dict(box_aspect=1)) In the example below the fonts are the same size but the subplots are not. I need each of the 5 subplots to be the exact same size with the exact same font sizes (axis labels, tick labels, etc) in the resulting PDFs. One has two subplots and one has three subplots (in both cases in 1 row). Use case: I am making two separate plots which will be saved as pdfs for an academic paper. My problem is setting the absolute size of the subplots. I know how to set the relative size of subplots within a figure using gridspec or subplots_adjust, and I know how to set the size of a figure using figsize.
