WebYou may be wondering why the x-axis ranges from 0-3 and the y-axis from 1-4. If you provide a single list or array to plot, matplotlib assumes it is a sequence of y values, and automatically generates the x values for you.Since python ranges start with 0, the default x vector has the same length as y but starts with 0; therefore, the x data are [0, 1, 2, 3]. soldiers point weather 7 dayWebPython Matrix.
