While the color map feature is useful, sometimes it is easier to manually specify the colors of each marker. Since we have used np.linspace to define 20 equally spaced data points between x=0 and x=5, we see 20 markers at these points. In this scatter plot, the marker is customed and is set to clubs. # Sort colors by hue, saturation, value and name. Here is how we can use it to change the marker color.

Output:eval(ez_write_tag([[300,250],'pythonpool_com-medrectangle-4','ezslot_1',119,'0','0'])); In this specimen, each point is marked using a circle marker. x,y: Float or array-like, shape(n,) – These are the two sets of values provided to the scatter function for plotting. Scatter Plot Color by Category using Matplotlib. in this example: Keywords: matplotlib code example, codex, python plot, pyplot Each of the arrays have the same length. A scatter … matplotlib.pyplot.scatter(x, y, s=None, c=None, marker=None, cmap=None, norm=None, vmin=None, vmax=None, alpha=None, linewidths=None, verts=None, edgecolors=None, *, plotnonfinite=False, data=None, **kwargs) [source] ¶.
