I'm using the latest version of Numbers (4.2) and am looking to plot a Line Graph, with a few sections highlighted in a color as shown:
Any leads on how to do the same?
Ah! Nevermind! I managed a workaround. Since I found no solution online I'll answer myself here in case it helps anyone.
Under Chart's Background & Border Style, select "Advanced Gradient Fill" as shown in Image 1
Then change the Gradient angle to 180˚. If you hover just below the Gradient Slider, you should see a + symbol. Use that to add more stops.
In the example below, I have 8 stops. (4 for each highlight zone). Each highlight zone would need 4 stops (in this order):
White (Chart Background Color), Red (Highlight Color), Red (Highlight Color), and White (Chart Background Color).
They are almost overlapping in pairs, and hence you can't see all 8 here. (Shown in Image 2)
The end result is shown in Image 3.
Sidenote: Had to club all 3 images into 1 image since you need at least 10 rep to post more than 2 links. (sigh!)
