Selecting Your Data in the New Metric Builder
From the chart tab of the Metric Builder, click on the "Add Value" button. You can either pick a column from the dropdown list or click on the column itself to select that data for your chart.
If you have a date column in your data, then Grow will automatically pick the first one for your chart grouping. You can change which column is being used (even with a non-date column). If there is no date column, click the "Add Date or Category" button and select the column you want to use for the grouping.
Selecting Your Data in the Basic Builder
To select a data series, you'll need to be in the chart tab of the Metric builder. This is after you have pulled in a report and verified that it is the data you want.
Expand the Data Series heading in the left-hand panel of the Edit Metric view. Go ahead and click the blue "Add Value" button.
You can then use the mouse selector to choose your data series. You can either click on a column or row header to select that entire area, or you can click and drag to select the respective cells in the spreadsheet.
Your data series will appear in the metric view area above your data.
Note: Grow will only display 365 data points in a chart, so you cannot display over a year's worth of daily data. This limit is in place to help keep your charts easy to read and quick to load.
Formatting Your Data
To format your data, you can expand the dropdown arrow next to your data series.
Each chart type will have different formatting options. Generally, you can change the color, line thickness, and style of data labels, among other things. You can see more details by checking out this article.
You can also rename your data series by clicking in the box in the header of the data series.
