I have a value from 1 to 8 that I want to show on the dashboard as arrows. All I can do are simple arrows: ↑↓→←. Is there a way to do this using unicode or extended ASCII where I can also get arrows like these?
Can I put a unicode character on the dashboard?
Those are HTML codes. How do you put them into the dashboard?
Use the dashboard template node for testing.
I don't see how a template could put a unicode symbol on the dashboard.
Right now, I am using a change node to take, for example, a payload of "4", and change it to an ALT-16 character (►).
There are more appropriate arrows in the Unicode world, but the dashboard only shows the standard ASCII set.
What widget you are using in the dashboard to display the arrows ?
Here an example using the template and the ui_text.

Thank you professor- I understand my homework assignment.
I am understanding a bit more and can display discrete arrows in the dashboard text node.
My problem is that I want to use one dashboard text node by sending the arrow code to it from a change node. But when I try to put "<P>←</p>" into msg.payload, I get gibberish in the text node.
Any ideas?
Thanks.
So what settings do you have in the ui-text node? please provide a flow showing the issue from the inject to the ui-text node
Hi, simply sending unicode string should work.
