I would also love to have this implemented. That is being able to not only
set the colors, but also the alpha values as an array.

I can use the scatter function to plot an array of points and give a
corresponding array of colors to set those points. Is it possible to
do the same thing with alpha values?
Right now, I'm restoring to calling plot with an 'o' marker for each
individual point, which is slow.

This started from a simple enough question, but it got me thinking about what
the fastest way to do this is (in case you have HUGE arrays, or many loops over
them). This may be old news to some of you, but I though

Hey! :o)
This should be simple, but i cant manage: I need to plot many dots with the
same x, like
plt.plot([3,3,3,3],[60,80,120,180],'+',markersize=8,mec='k')
The array for x values is silly, especially since the number of y values
may be rather large. Is there a way to enter a constant there?

hi,
I'd like to display a scatter plot where the size for each element is
fixed. Currently, when I modify the size of the figure, the size of a
marker is fixed, and I would like it to be proportional to the window.
I want this because the size of the marker indicates an extent, and I would
like it
cool. it's done!! Thanks!!!

Dear all,
how can I make a scatter plot without edgecolor?
import matplotlib.pyplot as plt
In [110]: plt.scatter(np.arange(10),np.arange(10,20),edgecolor=None)
Out[110]:
in this case I can use edgecolor='w' to solve it, but when points overlap,
this does not work anymore.
Any help will be appre
Hi,
When I make a scatter plot where the y-axis is logarithmic I expected that
points where the logarithm is not defined (0 and negative values) are
skipped (as for the plot function). But it seems that the scatter plot
assignes a value of 1e-1. So in that respect plot(x,1) and scatter (x,y)

Hi,
thanks for reply.
My problem is that I need to scatter data of different periods but in the
same x.
For example, the quantity x sold in March is 1 at price y of 2, the quantity
sold in April is 2 at price y of 3. I want the 2 points to have different
colors in the same graph!
Now I'm doing

Hi,
I'm trying to make a scatter plot of 2 variables using a thirds as filter to
have different colors.
Let's say I have those data:
x=1,2,3,4
y=2,3,4,5
z=0,1,0,1
Then I want the values of x and y corresponding to those of z=0 to be of a
color and those corresponding to z=1 to be of another co

Friends,
Someone please suggest me how to make scatter plot with a matrix data such

I have managed to get this functionality to work by using both the scatter()

Hi, Everyone,

me?Thank you!
The background.PNG is shown full screen with a resolution of 1024*768. The

column for X axis, second column for Y axis
I am plotting multiple scatter plots to the same axis. For each
scatter plot, all points have the same shape and color. I would like
the legend to display the shape and color of the data points in each
collection (rather than displaying a rectangle for the color). The
result should be similar to
