Excel Select Data Source horizontal Axis Labels

What is showing you "..."? Where are you selecting the weeks from? Is it a contiguous range, or a bunch of disconnected cells? Note that using a contiguous range is always going to be easier to work with and more reliable than separate cells.

I have two sheets...in Sheet1 is my data so I have 52 weeks across from C2 - BB2. In Sheet2 is my graphs. When I right click on a graph and select "Select Data" the Select Data Source box shows up. In the left box "Horizontal Category Axis Label" is where my 52 weeks are. When I scroll down to uncheck the weeks I do not want to show. it only goes to 50 then after 50 there are 3 dots that show "..." so it will not show week 51 and week 52 to uncheck them from showing

If you click on the filter icon floating to the right of the chart, all of the categories will be available for you to select/unselect.

Alternatively, if you put your data in a range with week numbers in the first column and values in the next, and convert the range into a table (Ribbon: insert tab > Table), you will be able to filter the table, and all items in a column (up to 10,000 I believe) will be available to select/unselect. Any hidden rows in the table will not be shown in the chart.

Your awesome!!!! thank you

Often there is a need to change the data labels in your Excel 2016 graph. The procedure is a little different from the previous versions of Excel 2016. You will add corresponding data in the same table to create the label. You can also create a new set of data to populate the labels.

1. Select the Chart that you have created and navigate to the Axis you want to change.

2. Right-click the axis you want to change and navigate to Select Data and the Select Data Source window will pop up, click Edit

3. The Edit Series window will open up, then you can select a series of data that you would like to change.

4. Click Ok

For a time series like months, when you click select data you will not have the option to directly edit the x-axis. However, you still can by simply clicking Edit Legend Series and choosing X values. However, if you graph is chronological or time series based you need to pick a complementary chronological data. For categorical data, you don’t need to worry about this. Also, you can directly change x values from Select Data Source window. But essentially the steps are the same.
