Is it enough to verify the hash to ensure file is virus free? The previous examples could certainly be refined. It also allows the axes object to be spanned across multiple rows or columns. The axis is drawn as a unit, so the effective zorder for drawing the grid is determined by the zorder of each axis, not by the zorder of the Line2D objects comprising the grid. Hi All, I am having trouble converting some histogram (hist) code written for an earlier version of matplotlib. First, we'll define our figure and make it an 8x8 square (the figure size is arbitrary, but works fine for this example). To produce a square plot in the overall case, we need to physically set the viewpoint proportion utilizing the accompanying order: In this example, we pass square as an argument to matplotlib.pyplot.axis(), it illustrates a square plot. Similarly, the major grids are placed with the spacing of 5 units and represented by a lighter line.
