Python pandas plot scatter unique11/19/2023 Imports and Test Data 'Date' is already a datetime64ns dtype from. Tested in python 3.8, pandas 1.3.1, and matplotlib 3.4.2 Choosing Colormaps in Matplotlib for other valid cmap options. Of couse you can create several plots on the same axes. and can take a c or color parameter, which must be a color, a sequence of colors, or a sequence of numbers. In order to specify that a certin plot should be on an already existing axes ( ax), you'd specify the ax keyword as seen in the documentation. plotting a column denoting time on the same axis as a column denoting distance may not make sense, but plotting two columns which both contain distance on the same axis, is fine. Whether that makes sense you have to decide for yourself. You can plot any column against any column you like. In contrast, if a was number of peas and c was voltage they should probably not be on the same axis. For example, if a was income and c was expenditures it would make sense to put both on the same 'money' axis. If it makes sense to put different columns on the same axes depends on what data they represent. You can verify that each call to plot returns the same axes that it got passed: import pandas as pdĭf = pd.DataFrame(np.random.randn(100, 6), columns=)Īx1 = df.plot(kind='scatter', x='a', y='b', color='r')Īx2 = df.plot(kind='scatter', x='c', y='d', color='g', ax=ax1)Īx3 = df.plot(kind='scatter', x='e', y='f', color='b', ax=ax1)Īlso, if the plot is the same graph, shouldn't the x-axis be consistently either 'a' or 'c'? The idea is not to pass an ax argument to the first call to plot and use the returned axes in all subsequent calls. In addition, the axes is returned by the function so it can be reused for further drawing operations. If the argument is not provided the function creates a new plot and axes. In detail: plot takes an optional ax argument. You ought to repeat the second call to plot, not the first, so there is no need for bx.
