Use min-max charts to show the spread of data – Charting Best Practice

Next time you want to make a chart to tell how your sales (defects, customer calls, page views, number of clicks, walk-ins etc.) are doing over a period of time, consider showing them in a min-max chart.

For eg. a min-max sales chart for the last 12 months tells average, minimum and maximum sales per each month. See below for an example:

Min Max Excel Chart - An Example of Monthly Sales Data

Min Max Excel Chart - An Example of Monthly Sales Data

These are really easy to create and can tell more than simple sales are up story. The best part is you can make the min-max charts with ease.

1. Have your data ready

The first step of course is to have the data ready. It is not always you have the minimum, maximum sales details for a give month, so you may want to summarize the data before moving to the next step. For our example, let us revisit ACME products (trivia acme link for curious mice out there). The data looks like this:

sales-data-min-max-avg-example

2. Create an Area Chart

create-area-chart-spreadsheetAs you might have already guessed, these min-max charts are nothing but area charts in disguise.

So, select the tabular data and click on “insert > chart” and select area chart (just the simple area chart, not the stacked area chart)

3. Format the Chart to Get the Min-Max Effect

This is the last step. First you may want to adjust the data series order of the area chart to ensure that the areas are overlapped properly. See below:

min-max-is-an-area-chart-really

To adjust the order, right click on any of the areas and select “format data series” option, then go to “series order” tab.

The only formatting necessary is filling the bottom most area with white color (the minimum part). But you can also remove the plot area background – the gray color and adjust the fonts. Also, you can adjust the colors of other 2 areas (average and maximum) and adjust the border line width of average to make it standout.

That is all, there are no further steps, so go ahead, create your own min-max chart and let the conversation begin.

6 Responses to “Make VBA String Comparisons Case In-sensitive [Quick Tip]”

  1. Rick Rothstein (MVP - Excel) says:

    Another way to test if Target.Value equal a string constant without regard to letter casing is to use the StrCmp function...

    If StrComp("yes", Target.Value, vbTextCompare) = 0 Then
    ' Do something
    End If

    • Fares Al-Dhabbi says:

      That's a cool way to compare. i just converted my values to strings and used the above code to compare. worked nicely

      Thanks!

  2. Tim says:

    In case that option just needs to be used for a single comparison, you could use

    If InStr(1, "yes", Target.Value, vbTextCompare) Then
    'do something
    End If

    as well.

  3. Luke M says:

    Nice tip, thanks! I never even thought to think there might be an easier way.

  4. Cyril Z. says:

    Regarding Chronology of VB in general, the Option Compare pragma appears at the very beginning of VB, way before classes and objects arrive (with VB6 - around 2000).

    Today StrComp() and InStr() function offers a more local way to compare, fully object, thus more consistent with object programming (even if VB is still interpreted).

    My only question here is : "what if you want to binary compare locally with re-entering functions or concurrency (with events) ?". This will lead to a real nightmare and probably a big nasty mess to debug.

    By the way, congrats for you Millions/month visits 🙂

    This is nice article.
    I used these examples to help my understanding. Even Instr is similar to Find but it can be case sensitive and also case insensitive.
    Hope the examples below help.

    Public Sub CaseSensitive2()

    If InStr(1, "Look in this string", "look", vbBinaryCompare) = 0 Then
    MsgBox "woops, no match"
    Else
    MsgBox "at least one match"
    End If

    End Sub

    Public Sub CaseSensitive()

    If InStr("Look in this string", "look") = 0 Then
    MsgBox "woops, no match"
    Else
    MsgBox "at least one match"
    End If

    End Sub
    Public Sub NotCaseSensitive()
    'doing alot of case insensitive searching and whatnot, you can put Option Compare Text
    If InStr(1, "Look in this string", "look", vbTextCompare) = 0 Then
    MsgBox "woops, no match"
    Else
    MsgBox "at least one match"
    End If

    End Sub
