Say I have a table like this:
| Date | Number |
| 0128 | 28800 |
| 0129 | 32500 |
| 0130 | 63410 |
| 0131 | 56400 |
| 0201 | 68700 |
| 0202 | 84060 |
And I can put a graph to show the data.
However, what if I add a new row to the end, I have to re-assign the range of the graph's data to make it redraw.
Is there any way that I can let the graph "know" that I have added a new row?
No, there isn't, unless you extend the range. All you need to do is include a bigger range then your data sits on. In your example, your dataset is on the range A1:B7. After you create a chart/graph from this range then click to edit this range and remove the last number so it would be A1:B and click on OK button. This way will chart/graph account for every newly added row in range calculated by chart/graph after you clicked on OK button.
