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
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:

2. Create an Area Chart
As 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:

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.

Hello...
In Power BI I have data that includes months by name only (e.g. May, April, December...)
I need to build charts etc. but i need the months to go chronologically... not alphabetically... I cannot seem to find the fix to this.... once again, my data does NOT have an actual date attached to it (like 02/01/2023)....only month names... can i use a helper table wher i id the month names as numbers 1 thru 12? and if so, how do i manage this to work for me ?
Thank you.

You need to setup an extra table to map each month name to a running number. A simple 12 row table like
Jan 1
Feb 2
Mar 3
..
Dec 12
Then create a relationship between this month table and your month column
Now, go to "table view" in Power BI and set the sort by column to month number for the month name column on this new table.
Finally, use the new table's month name whenever you need to refer to the month name in the visuals.
They will be chronologically arranged.
