I want to make a scatter plot of them giving each point a different color depending on these conditions: -BLACK if x i<10. I have the X, Y, and Z data, and then I have a 'color list' of the form: (r,g,b). Plt.plot(group, group, marker='o', linestyle='', label=name)īefore I show you how the resulting plot looks, allow me to show you the data output from the print() function. I have two numpy arrays, x and y, with 7000 elements each. I have a 3D Plot that I created using matplotlib, and I have a list of rbg values that correspond to each point. Here’s what that looks like in code: import pandas as pdĭata = pd.DataFrame()

Use plt.plot(group, group, marker='o', linestyle='', label=name) to plot each group separately using the x, y data and name as a label.

Iterate over all (name, group) tuples in the grouping operation result obtained from step one.

Use the oupby('Category') function assuming that data is a Pandas DataFrame containing the x, y, and category columns for n data points (rows).

In particular, you perform the following steps: For each group, you execute the plt.plot() operation to plot only the data in the group.

To plot data by category, you iterate over all groups separately by using the oupby() operation.

💬 Question: How to plot the data so that (x_i, y_i) and (x_j, y_j) with the same category c_i = c_j have the same color? Solution: Use Pandas groupby() and Call plt.plot() Separately for Each Group

The third array c provides categorical label information so we essentially get n data bundles (x_i, y_i, c_i) for an arbitrary number of categories c_i.

The first two arrays x and y of length n contain the (x_i, y_i) data of a 2D coordinate system.A Matplotlib color or sequence of color.įor non-filled markers, the edgecolors kwarg is ignored andįorced to 'face' internally.

If you want to specify the same RGB or RGBA value forĪll points, use a 2-D array with a single row. Note that c should not be a single numeric RGB or RGBA sequenceīecause that is indistinguishable from an array of values to beĬolormapped.
