Every widget in the library is unique and so is your use case. You don’t have to select a random widget from the library and change every aspect of it to match your requirements. You can get started with a fresh empty widget and input your metrics.
Inside Analytics homepage, click on New Report. Give it a title, set the required visibility and click on Create.
The Chart under New section lets you pick a module and enter the metric(s) you need.
Once you save this widget, it becomes a template which you can find under the Existing section of the library. From the Templates section, you can drag and drop prebuilt widgets for common use cases.
