Steps for adding slope line to Excel XY charts

Imagine you are analyzing app downloads for two weeks. Your data looks like this. You want to quickly visualize which apps have been downloaded more this week.

sample data for excel chart with slope line
  1. Select Last week & this week columns and create XY chart (scatter plot). You will get this.

  1. In a blank range, create slope series like this. The starting values will be 0,0. Ending values can be manually typed or you can use MAX() formula to generate them from data.

  1. (continued). Now add this slope series to the scatter plot. We will end up with this chart.

  1. Change the slope series to “Scatter with straight line” type of chart. To do this, right click on the orange dots (slope series) and select “Change series chart type”.

Slope line in XY charts – When to use them & tips

Slope line is a great way to enhance the readability of certain types of scatter plots. Consider adding them whenever you are visualizing data from two time periods or two similar situations. Examples are,

  • Last year vs. This year sales
  • Male vs. Female customers by stores
  • Failure rate in machinery before and after maintenance
  • Test scores of students in two different subjects

Tips for working with slope line:

  • Always annotate the axis (use either axis titles or put text boxes near them)
  • Consider highlighting few of the points on charts based on the value. For example, we can highlight apps that have significantly change in downloads. Like this:

Here is a tip on how to highlight important points on a chart.

    I would apply a filter and use function subtotal, with option 9. This way you can see multiple views based on the filter.

  2. Michael Azer says:

    hey Chandoo, the solutions you proposed are very efficient, but if I wanted to be fancy I would do it this way .. the references are as your example workbook.
    =SUM(INDIRECT("C"&(MATCH(F5,B5:B95)+4)):INDIRECT("C"&(MATCH(F6,B5:B95)+4)))

  3. Luke M says:

    I like things simple:
    =SUMIF(B5:B95,">="&F5,C5:C95)-SUMIF(B5:B95,">"&F6,C5:C95)

  4. Matt S says:

    use something like: =SUM(OFFSET(B1,0,0,DATEDIF(A1,D1,"d")))
    and have D1 be the date that I want to sum to.

  5. Tom J says:

    In Excel 2003 (and earlier) I'd use an array formula to calculate either with nested if statements (as shown here) or with AND.

    {=SUM(IF(B5:B95>F5,IF(B5:B95<F6,C5:C95,0),0))}

    Note that I truly made this for BETWEEN the dates, not including the dates

  6. Andrew says:

    I turned the data set into a table named Dailies.
    I named the two limits StartDate and EndDate.

    And used an array formula:

    {=SUM((Dailies[Date]>=StartDate)*(Dailies[Date]<=EndDate)*Dailies[Sales])}

  7. Frank Linssen says:

    If I would still be using the old Excel I would do it as follows:

    SUMIF($B$5:$B$95,"<="&H6,$C$5:$C$95)-SUMIF($B$5:$B$95,"<"&H5,$C$5:$C$95)

    Works as simple as it is.

    Thank you for this formula, I've just spent ages trying to find something to work on my data, I knew it would be possible! Don't care if others think there are easier/other ways to do it, you explained it so I understood it and could apply it to what I was doing so I'm happy!

    Hi

    I have a list of people's names in column A, I have a list of dates in column B which records the dates they have been off sick, in column C I have either 1 if it is a full sick day or 0.5 if it is a half day.

    What I would like to do is to add up the number of dates a specific person has been off within two dates.

    For example, I want to look at my list of names and to find Joe Bloggs (column A), then add up all his sick days (column C). The start date will be in cell E1 and the end date will be in F1.

    If this possible using SUMIFS?

    List of names are in range A2:A100

    List of dates in B2:B100

    List of sick days (either 0.5 or 1 in C2:C100

    The start date is in cell E2

    The end date is in cell F2

    Your help would be greatly appreciated.

    • Loknathan says:

      Yes, with the help of SUMIFS you can have the solution.
      Note: you need have an extra col. D2 where you will input Name of the person.
      =SUMIFS(C2:C100,A2:A100,D2,C2:C100,">="&E2,C2:C100,"<"&F2)

      Col. A Col. B Col. C Col.D Col. E Col. F
      Name Date Sales
      ABC 28-Jun-11 1 MNO 28-Jun-11 25-Sep-11
      XYZ 29-Jun-11 0.5
      MNO 30-Jun-11 1
      PQR 1-Jul-11 1

  21. AC says:

    Thanks for this - it solved the problem that I was having. However can someone please explain to me why the "" needs to be around >= and <= as well as why we need to add & in order for the formula to work? Thanks in advance!

  22. Ufoo says:

    This formula works perfectly as well. Any ideas?: =SUM(INDEX(C5:C95,MATCH(H5,B5:B95,1)):INDEX(C5:C95,MATCH(H6,B5:B95,1)))

  23. Ufoo says:

    ikkeman had posted the same thing.

  24. murray says:

    I am trying to sum total a range of cells between date ranges ie column n has $ amounts column d has the transaction dates ie 1/3/2015 or 25/3/2015 or 25/4/2015 column b has the text saying drp or distribution - reinv

    In another cell I am trying to sum or total (in column n) with the value of a range of different dates (column d) that contain different text (column b) ie cell n48 is 50, n65 is 85, n165 is 36

    with the dates ie cell d48 is 1/3/2015, d65 is 25/3/2015 and d165 is 25/4/2015

    with different text that says drp or distribution - reinv ie cell b48 is drp, b65 is distribution - reinv, b165 is drp

    If I wanted to sum the amounts between 1/3/2015 to 31/3/2015 with drp then the total would be 50. Also if I wanted to sum the amounts between 1/4/2015 to 30/4/2015 with drp the sum total would be 36 If I wanted to sum the amounts between 1/3/2015 to 31/3/2015 with drp and distribution - reinv the sum would be 115

    What would the formula be for these different questions

    hope you can help, it has been driving me nuts and cant work it out
