Description

Select from the granularity drop-down to change a trended visualization from daily to weekly to monthly, etc. The granularity is also updated in the data source table.

You can overlay a min and max value label to highlight the minimum and maximum values in a metric. The min/max values are derived from the visible data points in the visualization, not the full set of values within a dimension.

You can choose to add a regression or moving average trendline to your line series. Trendlines help to depict a clearer pattern in the data. When selected, select a model from the list. See Models for an overview and description of available models.
.

TIP It is recommended that trendlines be applied to data that does not include today (partial data) or future dates. Today or future dates skew the trendline. If you need to include future dates, however, remove zeroes from the data to prevent skewing for those days. Go to the visualization’s data source table, choose your metric column, then enable Column Settings > Interpret zero as no value.

Model

Description

Create a best-fit straight line for simple linear datasets and is useful when the data increases or decreases at a steady rate. Equation: y = a + b * x

Create a best-fit curved line and is useful when the rate of change in the data increases or decreases quickly and then levels out. A logarithmic trendline can use negative and positive values. Equation: y = a + b * log(x)

Create a curved line and is useful when data rises or falls at constantly increasing rates. This option should not be used if your data contains zero or negative values. Equation: y = a + e^(b * x)

Create a curved line and is useful for datasets that compare measurements that increase at a specific rate. This option should not be used if your data contains zero or negative values. Equation: y = a * x^b

Finds the best-fit for a dataset shaped like a parabola (concave up or down). Equation: y = a + b * x + c * x^2

Create a smooth trendline based on a set of averages. Also known as a rolling average, a moving average uses a specific number of data points (determined by your Granularity selection), averages them, and uses the average as a point in the line. Examples include a seven day moving average or a four week moving average.
