Is it possible to create a horizontal band (not the entire wall) of color on a line chart? If so, how. Thanks.

Please demonstrate (somehow, for example by an image) what you want to achieve really.

Just a tip: an added Graph of constant values and with thick color line?

Insert an Image as a background. See attachments.

How do I change part of the background on a (blood sugar level) line chart

I wish to have a line chart showing a simple 2 column data range (Date, Blood Sugar Level). In addition I wish to have the background of the chart to hignlight the acceptable range of what the blood sugar level should be, i.e. a data range of between 4 to 7 for all dates to be light grey. I should then end up with a graph that shows the acceptable range in grey and for the line graph to sit on top of this - easily identifying when the line chart data exceeds to acceptable range. Can anyone help…
