Question

I'm doing a heatmap. I have a list of list in this format

[ [x1,y1,value1], [x2,y2,value2]... ]

I have done a Dataframe like following:

           X         Y   VEL
0  -4.799990  1.599996   93.294099
1  11.199978 -1.599996   97.714788
2 -14.399973 -1.599996  131.289188
3   4.799990  4.799995  118.418184
4   4.799988 -4.799995   91.098021
5  -4.799988 -1.599996   91.177642
6  -1.599996  4.799989   85.077989
7   4.799989  1.600002   67.702695
8   1.599995 -1.600002  110.756954
9  -1.599995 -4.799989  112.697441

I want to put in 2D axis with seaborn putting on them vel

I have this code. list is in the format that I have told before. pd is pandas library sb is seaborn library

 df = pd.DataFrame(list, columns=["X", "Y", "VELOCIDAD"])

    df = df.head(10)
    print(df)
    data_extract = pd.pivot_table(df, values='VELOCIDAD',
                                  index='X',
                                  columns='Y')

    plt.show(sb.heatmap(data_extract,cmap="YlGnBu"))

I get the following graphic: Result

Thanks in advance.

Answer 1

if you want 'Vel' values to be put on them try: plt.show(sb.heatmap(data_extract,cmap="YlGnBu", annot=True))
