If you want to use that equation anywhere in your spreadsheet, you have to manually enter it. The first is that the equation displayed on the chart cannot be used anywhere else.
The chart trendline method is a quick way to perform a very simple linear regression and fit a curve to a series of data, but it has two significant downfalls.
Now we know that the data set shown above has a slope of 165.4 and a y-intercept of -79.85.Įasy, right? Linear Regression with the LINEST function We’d follow these 6 steps (in Excel 2016): Let’s say we have the data set below, and we want to quickly determine the slope and y-intercept of a best-fit line through it. You can go from raw data to having the slope and intercept of a best-fit line in 6 clicks (in Excel 2016). Add the equation to the trendline and you have everything you need. When you need to get a quick and dirty linear equation fit to a set of data, the best way is to simply create an XY-chart (or “Scatter Chart”) and throw in a quick trendline.

After the macro code is written and saved, it can then be attached to certain triggers in the Excel model. The user will create, code, and save macros here. The coding section is where most, if not all, the coding happens. The properties section in the bottom left will only be used for more advanced macros that use UserForms to create graphical interfaces for the macro. The file structure section is only used for creating a new macro file.
Most of the time, the user will be working in the coding section. This may seem overwhelming at first, but in reality, it’s simpler than it appears. When done properly, this will open a window with a file structure tree on the top left, properties on the bottom left, a debug pane at the bottom center and bottom right, and the coding section that takes up the majority of the screen in the center and top right. To access the VBA window, press Alt + F11 within any Office program. The second and more powerful method of creating an Excel macro is to code one using VBA. IKt means that macros made in this way are very hard to use with variables and “smart” processes. By default, recorder macros also use absolute referencing instead of relative referencing. However, the downfall of this method is that it is not very customizable, and the macro will mimic the user’s input exactly. This method will work for simple processes. This method is relatively simple and requires no inherent knowledge of the VBA code. When the user ends the recorder, this macro is saved and can be assigned to a button that will run the exact same process again when clicked. After activating the recorder, Excel will record all the steps a user makes and save it as a “process” known as a macro. The first method is to use the Macro Recorder.
While users cannot directly manipulate the main Excel software through VBA, they can, however, master the art of making macros to optimize their time in Excel.
