CodePudding user response：

The chart is not so complex. But your data is not laid out optimally. The #N/A in the Y value columns will not plot points, but all the blanks in the date column are messing you up.

Delete all those rows below row 33. They are what is killing the chart.

Now select the range A7:R33, and on the Insert tab of the ribbon, choose Table. This converts the range into a Table, which is a data structure with advanced properties.

Make sure the chart uses the columns of the Table as its data.

When you add new data to the row below the Table, the Table notices and expands to include the added row. Formulas that reference a whole row of the Table will also expand to include the new row. This means the chart will expand to include the new data.

Here's a tutorial I wrote long ago about the magical dynamic nature of Tables: Easy Dynamic Charts Using Lists or Tables.
