Script to create a drop down list that change the font size for bar chart label

[David Law 2]

Hi,

I would like to write a python script to create a drop down list for user to change the font size of the bar chart label.

Does anyone have an example on how to do it that I can use as a reference

Many thanks in advance!

Please check this question:

and this site:

You can add an integer document property (say labelSize) that is set in the drop down, then attach a script to this document property, such as the one below, where barchart is an input parameter of type Visualization (your target barchart):

Font is part of the Microsoft System.Drawing namespace:

https://docs.microsoft.com/en-us/dotnet/api/system.drawing.fontview=dot...

If the default font is not on your machine you can download and install it on Windows, or you might want to specify another font name directly. Looks like Iron Python can only access the installed fonts.

from Spotfire.Dxp.Application.Visuals import *

from System.Drawing import Font

newsize=Document.Properties['labelSize']

barchart = barchart.As[Visualization]()

myfont = barchart.LabelFont

newfont = Font(myfont.Name,newsize)

barchart.LabelFont = newfont
