To improve comprehension of chart data, it is sometimes very helpful to explain what each data series represents. E.g. if the series names say "orange", "apples", and "bananas" the legend could say Fruit [lbs].
While this information could be added in the chart title, it can make that title too long.

I've been working on a school assignment where we need to show the correlation between 2 sets of data but the range of them both is far apart. On the support page I saw the function only works in Word. Why?

My suggestion is that this function in also added to Excel.

How about making your Mac version intuitive? It's hard to find stuff.

Currently, Selecting the Vertical axis (Primary or Secondary) and Data Label options are not available while Selecting Data for a chart. This creates innumerable problems while charting, especially using large data sets. This is leading to non-display of charts if Data set is more than 1000 in numbers.

Preferably, an option should be available also to Turn-Off all Data Labels by default.

In many versions of Excel, you can add data labels that correspond with a specific cell value.This is particularly useful in a scatterplot or bubble chart. Please add this feature to Excel for Mac.

I do a lot of XML mapping (import XML data to Excel, Export XML format) and every time I have to do this, I need to go Windows machine, which, for those who doesn't know, is a terrible experience by itself. There is a reason I love Mac. Please make Mac the only computer that I'd be using for any need.
Thanks,

Make it easy for teachers to check type of graph a student has used. It is very easy on Windows. Mac should be just as easy.

The excel function need to add the forecast function so you can use it to makw a easier forecast.

The "Change data label"&"Insert data label field" are not available in MS Office Excel 2019 for Mac. It would be great if you could update and guide me on the same.

Allow bars (points) of of Sparkling chart t be coloured depending on the value of individual points. Currently Sparklines lines only show trends in one colour. Allow the user to format the colour of the different bars (points) of a Sparkling chart

Be able to filter information in the chart, similar to what exist on windows.

As of March 2020, I can change the order of data series for a chart either by using the arrow buttons in the Chart Source Data dialog or by changing the order value in data series definitions in the formula bar; but (at least for line charts) this does not alter the data series order in chart legends.

Search results for "change Excel chart legend data order" indicate the Windows version matches the legend data order to the chart data order when changed, as it should. Need to do that for the Mac version, too.

Since there are small islands such as Ogasawara Islands in the south, if you include the data of Tokyo in Maps and set Map Area to Only regions of data, the map will be displayed very small, so I want only the main island of Tokyo will be displayed and the small islands won't be shown in the map for visibility reason.

My idea is to get the bounds/scale range thing sorted out again and running like it used to. Data is not looking at the time it's plotted against and to get it to show up on our graphs now, you have to re-set the bounds, which makes the scale not correct to the data.

In all the charts I've looked which is most you can format the axis to change the way the units are displayed like in hundreds, thousands, millions...
The Waterfall chart doesn't allow for this. The format axis dialog box to the right doesn't have this choice. Please see the attached file.
