Check out the following discussion on a similar issue
I have shared a site name from where I use transparent images for custom shapes. It might be useful for you too.
Hope this helps!
I've had a look at that site, and none of the shapes there would do what I am looking for (I've looked at a number of those sort of sites on line already to no avail).
But thanks for your help
Thanks Manoj - your shapes worked perfectly
Thanks for your quick assistance - I really appreciate the help everyone on these forums provide
However from what I can see, your solution didn’t help me
From what I can see, you are using the standard shapes for male and female, and have just made them larger than my ones, and used two different colours of blue, which does make it easier to see the difference between male and female. I alread knew how to do that
However my Viz is already using the colours to show a different attribute of my data, so I can’t use different colours to distinguish, and because I have a large amount of data that I am trying to fit on one page, I can’t make the shapes very big. As such, it was very difficult to tell the difference between the male and female shapes
Manoj's solution worked perfectly and has solved my query
Regards, and thanks again
