Use pattern fill in chart?

[EmmaWB]

Hi all,

I'm working on making my reporting more accessible, and as part of that I don't want to rely on color alone to differentiate layers in a chart. Is there any way to fill a bar chart layer with a pattern (stripes or something)? On line graphs you can make markers different shapes, but I'm trying to figure out how to differentiate layers on a bar chart without solely relying on colors.

Thanks!

Can you please share some sample data so that I can build on that?

I've attached a super simple workflow as an example.

What I'm looking for is a way to change the fill pattern of one of the layers, like this:

Currently, I don't think we have the option of being able to change the fill type in Alteryx. Solid color (constant or variable) fill is the only bar chart fill.

In case anyone else has this problem, we've submitted an idea for future development. Please go like it so we can see this as a native feature in the future!

In the meantime, I used a combination of these two resources to meet my immediate need:

• Using the Python tool, I created a custom visual and used pattern_shape_map to assign fill patterns.
• Then I used this tutorial for saving a temporary image and reading in the image file path since the Python tool can't output images.

I've attached my solution workflow. Hope this is helpful for anyone else who is trying to use fill to increase the accessibility of their visuals!
