Conditional Formatting.
The Fill feature can do that.
On request, cells are automatically filled with data, usually based on cells above, or to the left.
You need to use Conditional Formatting.
When a function argument is automatically entered by Excel, it typically refers to the use of the AutoFill feature or the formula suggestion pop-up that appears as you type a function. Excel may suggest arguments based on the context of the formula or the data in the surrounding cells. Additionally, if a function requires multiple arguments, Excel may highlight the necessary cells or provide hints to guide the user in inputting the correct values. This feature enhances user efficiency by reducing the need for manual entry.
It will immediately redraw the chart based on the new value
Yes, unless the chart is generated by a VB macro.
You can export a spreadsheet to HTML to view on the Web, but you can not operate Excel from a web browser.
There is something called a workbook dump. It is excel-based, and can be used to export data from HySYS to excel.
In Excel, a cell reference with dollar signs, such as $A$1, denotes an absolute reference. This means that if you copy the formula to another cell, the reference will not change and will always point to cell A1. In contrast, a relative reference like A1 would adjust based on the position of the cell where the formula is copied. This feature is useful for maintaining specific references in calculations across different cells.
It is not time based. Normally Excel is in what is known as Automatic Recalculation mode. When this is the case Excel recalculates any time any change is made to the spreadsheet, like typing in a new number or a piece of text. If it is in Manual Recalculation mode, then it only recalculates when the user presses the F9 key.
A chart in Excel is dynamic, meaning it will automatically change as the data changes. A paper based chart won't do that. Excel charts can have all sorts of features and can be customised to the way the user wants. Those are some of the advantages. A paper based chart can sometimes be more accurate than an Excel one in the way it is drawn, like X Y diagrams. It is much easier to add notes to the chart when it is printed. A user can handwrite on it to make important notes about it.
You do Conditional Formatting based on a cell value or based on a formula.
