The other half of the marker is filled with *markerfacecoloralt*. - 'none': No filling. For examples see :doc:`/gallery/lines_bars_and_markers/marker_fillstyle_reference`.

Parameters ---------- every : None or int or (int, int) or slice or List[int] or float or (float, float) Which markers to plot. - every=None, every point will be plotted. - every=N, every N-th marker will be plotted starting with marker 0. - every=(start, N), every N-th marker, starting at point start, will be plotted. - every=slice(start, end, N), every N-th marker, starting at point start, up to but not including point end, will be plotted. - every=[i, j, m, n], only markers at points i, j, m, and n will be plotted. - every=0.1, (i.e. a float) then markers will be spaced at approximately equal distances along the line; the distance along the line between markers is determined by multiplying the display-coordinate distance of the axes bounding-box diagonal by the value of every. - every=(0.5, 0.1) (i.e. a length-2 tuple of float), the same functionality as every=0.1 is exhibited but the first marker will be 0.5 multiplied by the display-coordinate-diagonal-distance along the line. Notes ----- Setting the markevery property will only show markers at actual data points. When using float arguments to set the markevery property on irregularly spaced data, the markers will likely not appear evenly spaced because the actual data points do not coincide with the theoretical spacing between markers. When using a start offset to specify the first marker, the offset will be from the first data point which may be different from the first the visible data point if the plot is zoomed in. If zooming in on a plot when using float arguments then the actual data points that have markers will change because the distance between markers is always determined from the display-coordinates axes-bounding-box-diagonal regardless of the actual axes data limits.

Parameters ---------- drawstyle : {'default', 'steps', 'steps-pre', 'steps-mid', 'steps-post'}, default: 'default' For 'default', the points are connected with straight lines. The steps variants connect the points with step-like lines, i.e. horizontal lines with vertical steps. They differ in the location of the step: - 'steps-pre': The step is at the beginning of the line segment, i.e. the line will be at the y-value of point to the right. - 'steps-mid': The step is halfway between the points. - 'steps-post: The step is at the end of the line segment, i.e. the line will be at the y-value of the point to the left. - 'steps' is equal to 'steps-pre' and is maintained for backward-compatibility.
