Try to create the same button in dummy dashboard and publish it on server.
if still get the same problem then share your dummy dashboard with me.
Hi Tom Myers,
I think there is blank space at the end of text.
There's no blank space.
The issue here is the view I've got on desktop is different to that being published to the server.
Some Text format is not supported on Tableau server and by default it changes into Arial format.
Since the word Contribution is off the page, I'd say its a font size issue that is preventing the complete message from showing. You can either make the box bigger, or the font smaller and it should appear.
As to the why it is doing this - it could be a few reasons but I'd be looking at you have word wrap turned off in the Text mark menu in the first instance. You get to this by selecting the text button, drop down the alignment menu and look for the wrap section.
I create my buttons as PNG files and then put them on a sheet by themselves to be used in a dashboard. By doing this, I know that the button will always look the same and will resize well. Maybe this would be of help to you.
