Your site has been very useful, and I appreciate all of your tips and techniques. I want to make a similar type of Two Color XY – Area Combo Chart. I have tried your technique as well as others, but it seems that I had made some mistake and I was struck in 2nd X axis calculation on wards. Please help me to overcome this problem and please upload a sample file of the same so that it will be very useful for me and your site followers.

Thanks in Advance

You need another column with the X values needed by the area chart series. Insert a column between columns J and K, Put this formula into cell K2:

=(J2-J$2)/(J$115-J$2)*10000

and fill it down to K115. You may decide it makes sense to change J2 to 1/6/2011 and J115 to 1/13/2011 (dates only, no times). Also change the formatting of column K to a number or general so it’s easier to read. Your chart already has the data from J and L as the XY series, now copy the data in K:L, and paste it into the chart as in the example in this tutorial.

Since some of the area regions are very thin, it may be best to use no line for the XY series, so this line does not obscure the fill.

Your site has been very useful, and I appreciate all of your tips and techniques. I am having trouble filling the area under a step chart. I have tried your technique as well as others, but it seems that my axis scale is too small to resolve?, since it is reduced down to seconds and the smallest axis unit is a day. Essentially, my data comprises of time (start and end time) and length that a light bulb is either ON (height of 1) or OFF (height of 0). Seems basic, but deceptively not. I have uploaded the file here: http://www.4shared.com/file/TQKP-3D3/104_StepChartNeedsHelp.html.

Chart (1) is the step chart that I created, and chart (2) is what I am trying to accomplish (for this example, I filled in the area using the shapes tool. Not very precise.).

Thank you so much for your help,
Kristina
