I tried that before posting, but didn't think it worked since when you click "Apply" within the Font screen it does nothing, but when you click Apply in the Properties screen it takes effect. That's pretty annoying, they should probably remove the Apply button in the Font screen if it doesn't actually apply to anything..
You can try this solution:
"Go to chart properties>>Style tab>> Look:Select the first Style.
Go to Presentation tab:Enable checkbox Show dimension label>.Click on font and configure settings accordingly."
