Automatic updating charts in excel grandstream phone not updating time
It's important to remember that you enter new data in a contiguous manner.
If you skip rows or columns, this technique won't work as expected. Because the chart defaults will use the label headings in each column for each series name, you can't use those labels to name the dynamic ranges.
If you want to advance beyond your ordinary spreadsheet skills, creating dynamic charts is a good place to begin that journey.
Another approach is to add new data to the range not at the end, but somewhere within the range.
For instance, you may have some data that represents a time period, such as 11/1 through 11/13, and you create a chart based on those dates.
When either is the case, there's a more complex formula method.
It relies on dynamic ranges that update automatically, similar to the way the table does, but only with a little help from you.
The key is to define the chart's source data as a dynamic range.
