# Uvažanje podatkov

Obstajata dva glavna načina za uvoz novih podatkov v Grafih, uvoz podatkov neposredno iz datoteke ali ustvarjanje novih podatkov z enačbo.

A wide array of filetypes are supported when importing data by file. Graphs currently supports Panalytical .xrdml files, Leybold .xry files as well as files that are saved in a column format such as most .csv files, .dat files, .xy files or plain text. Finally, data from other Graphs projects can be imported into the current project as well, simply by adding new data as usual, but by selecting a project file instead.

When using a custom delimiter during the import, an extra field will be visible to enter the delimiter of choice. This field recognizes regular expressions. For example, to choose a delimiter that looks for whitespace, one could enter `\s+` as delimiter. In this example, `\s` denotes that the delimiter is a whitespace character, and the `+` denotes that at least one or more whitespace is required. Thus this input looks for any amount of whitespaces including tabs. Note that this particular input is equivalent to the default Whitespace option.

The other way to import data is to generate data directly using an equation. This can be done using the "Add Equation" button found in the top-left corner, or by pressing Ctrl+Alt+N. Most commonly used syntax is accepted, with an `x` denoting the x-coordinate. A simple quadratic equation could for instance be created using `x²+5` as input. Be aware that trigonometric functions are using radians by default. If you want to use degrees, simply add a `d` to the trigonometric function. For instance `cosd(x)` generates a cosine where the x coordinate is given in degrees while `cos(x)` generates a cosine with the x-coordinate in radians.
