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

In the "Add or remove a secondary axis in a chart in Excel" support page (MacOS version) in support.office.com Word is erroneously used instead of Excel, confusing the poor reader (All languages!).

create a checkbox option that is:
- bold to read (visually striking instead of utterly subtle as it is now. see google sheets for example)
-easy to insert
-easy to copy and paste across columns/rows
-automatically centres in cell
And, it would be fantastic if Excel preserves the checkboxes from GoogleSheets instead of turning it into TRUE FALSE.

Following the help instructions for secondary axis is useless, because the menu does not contain Secondary Axis until you've added one. The only way to do it is to right-click on the series and choose "Format Data Series...". At least please fix the help, but even better would be to fix the menu item.

It is nice in a column chart to see meaningful pictures instead of boring bars. Mac only allows you to import an image. Windows supplies a library of icons making it easier and more robust.

Previously, there were ways to program custom keyboard shortcuts to insert different charts. In Excel for Mac 16.30, there is no way to do this. For those of us who make lots of charts, this is very difficult. Even making it possible to change the default chart so that the new alt + F1 command can be used would be a big step forward.

Histograms that allow multiple series would be ideal (ie. in stacked form as well as side-by-side comparison). The current solution (as far as I know) is to custom-make it with bar charts. A large part of the statistical analysis I do requires distinct series being compared.

In Excel 2016 for Mac, new chart types were introduced, including Histogram, Tree Map, Sunburst and Box and Whisker. When attempting to format the X & Y Axes, either the Format box appeared with no parameters, or no Format box shows at all. This is critical, core functionality and is needed ASAP, for example a 16.10 update. With my specific case, /i was trying to adjust Bin parameters on a Histogram, and the Format Axis box never appeared.

Add customize color option to excel for mac to change color themes to set it as default

Bring filtering charts to Excel for Mac.

I read about this feature here: https://blogs.office.com/en-us/2014/02/04/filtering-charts-in-excel/

But I couldn't find how to use them in Excel for Mac (16.12).
I found https://answers.microsoft.com/en-us/msoffice/forum/msofficeexcel-msomac-mso_mac2016/chart-filter/e5e49410-6ffc-499f-bdeb-e6f8a151bd4c which claims they are not supported. This would be a useful feature to bring Excel for Mac closer to Excel for Windows.

I'm told by your support staff that one cannot resize a chart that is itself a sheet, ie not an object in a sheet. So to resize a chart I have to copy/move it to be an object in another sheet. Big pain.

Why isn't power view and powermaps as a add in for Mac available?

Add design tab to Excel for Mac so I can create custom color and font themes for my graphs so I don't have to re-enter the design elements for every single chart.

In Excel Windows versions it is possible to place macro buttons and other controls also on chart sheets - an awesome toolset to create dynamic charts where content can be altered by user.
Why is this feature not available on Mac?
Add control does not respond on chart sheets. Even worse - charts with controls created in windows versions lose all this content when opened on Mac!
