Y-axes and metrics

The chart is visualized, based upon two y-axes (left and right). The metrics for these two y-axes are predefined but can be changed when creating or editing a chart. When there are more than two metrics in the chart, the data will be visualized with "invisible" y-axes. This means that a chart can have more than two y-axes.

Y-axes ranges

As a default, the platform will set the range based on the measured data. You can change this per metric by filling in the Min and Max when editing the widget.

How to set your y-axis

You can set the y-axis to your own preference. This can be done when creating a new chart or when editing an existing chart.

How to set the y-axis for a new chart

Take the following steps to set the y-axis for a new line or bar chart.

Go to a dashboard that you would like to add a new line graph or bar chart to
Click on + Add widget
Choose the chart that you would like to create (line or bar chart)
Choose the aggregation that you would like to use for your chart.
Fill in the widget title, select your data sources, and set the interval and period settings.
Scroll down, under Units, to set the Chart options.
Select the left Y-axis and the right Y-axis by clicking on the predefined metric.
If needed, fill in the y-axis range per metric. If the y-axis is not filled in, the platform will automatically fill in the range based on measured data.
Click on Create to save your widget.
Your widget is now added to your dashboard!

Changing the y-axis from an existing chart

Changing the y-axis in Explore

You might want to change your y-axis in Explore when you are viewing data from more than two metrics. You can plot a different metric on the left y-axis, through the legend. Just click on the metric that you want to plot on the left y-axis. The platform will automatically change the y-axis and the visualization of the data.
