I am hoping this will be a very simple question to answer.
I have a bar char with the values 00 to 23 on the x axis (essentially hourly increments). I have coloured the bars that are in the range 09 through to 17 hours. However, what I would prefer is to shade the background of the chart to highlight this range rather than the bars themselves as these will need to be coloured depending on the value of the y axis.
Is there any way to do this, if not does anyone have a different solution to the problem?
