Any of those help You can plot each category separately on the same axes, and let Matplotlib generate the colors and legend:
code :
fig, ax = plt.subplots()

groups = pd.DataFrame(X_tsne, columns=['x', 'y']).assign(category=y).groupby('category')
for name, points in groups:
    ax.scatter(points.x, points.y, label=name)

ax.legend()

R Treemap labels don't justify when using fontsize.labels set to 0 for top level labels?

Any of those help I believe this is due to a bug that causes all label wrapping to be based on the first element in the fontsize.labels vector, rather than the element that relates to the level in question. One workaround to this problem is to set the fontcolor.labels and bg.labels arguments in the treemap function to make the labels transparent (note that bg.labels can either be a colour name or a value from 0 to 255 indicating opacity). In your example this would be:
code :
tm <- treemap(business,
              index=c("NACE1", "NACE2"),
              vSize="x",
              vColor="data.available",
              type="categorical",
              fontsize.labels = 16,
              fontcolor.labels=c("transparent", "black"),
              bg.labels=0
)
How do you make ggplot labels use both labels = abs and labels=comma?

hop of those help? I'm creating a population pyramid. I would like my axis to use absolute values so that I don't have negative numbers for population count. I would also like to have the tick marks on the x-axis formatted with commas so that instead of 30000 it would read 30,000. , You can make a new function that does both abs and comma
code :
abs_comma <- function (x, ...) {
  format(abs(x), ..., big.mark = ",", scientific = FALSE, trim = TRUE)
}

I think the issue was by ths following , Make the labels automatically adjust their size to their content by setting their AutoSize property to true:
code :
 lbl[i] = new Label();
 lbl[i].Text = "" + i;
 lbl[i].Location = new Point(30 + (i * unit), 380);
 lbl[i].Visible = true;
 lbl[i].AutoSize = true;
 this.Controls.Add(lbl[i]);

seems to work fine After some reverse engineering with an example from adjustText library and my own example, I just had to change my for loop to create the labels and it worked fantastically.
code :
    labels = ['{}'.format(i) for i in zip(a, b)]
    texts = []
    for x, y, text in zip(a, b, labels):
        texts.append(ax.text(x, y, text))
    adjust_text(texts, force_text=0.05, arrowprops=dict(arrowstyle="-|>",
                                                        color='r', alpha=0.5))
Given a set of labels and x and y coordinates, how do I output the first 6 nearest neighbors for all labels in Python?

With these it helps Per label, you would have to calculate the distance of each point from your label. Assuming you have implemented a distance() function -
code :
for label in points:
    distances = []
    for remaining_point in points:
        distances.append (distance(label, remaining_point))
    distances.sort()
    print (distances[1:7]) // As the point matching itself would have a distance of zero.
