A line chart connects points with lines to show changes in value. The horizontal axis represents a continuous progression, oftentimes, while the vertical axis displays values for a metric.
Line charts are ideal for representing continuous data and comparing trends in multiple series. For example: Tracking profit changes for different departments over time. You could have one line for each department, and the progression from left to right would show how the profit changed in successive quarters. Each line represents a department’s trend, making it easy to follow. Use line charts for time series data or when there’s a sequence on the x-axis, for example, dates, months, or quarters.
To create the Line chart
(Refer to Dashboard Basics > Query)
On the right side of the default screen, select Visualization as Time series to create an Line Chart panel.
There are multiple options to edit the properties of the panel. The first one is Panel Options. Enter a Name and Description for the Panel that you want to create. For instance, if you’re making a Line chart to track CPU usage, name the panel “Line Chart” and describe it as “CPU Usage.”
The Description is available in the top left corner and can be viewed by hovering over the i button.
The next part of Panel Options is Panel Link where you can point a link to any other website or dashboard of your choice. Enter a title, and URL, and select the ‘Open in a new Tab’ option if you want to open the link in a new tab. Click Save.
The URL can be a link to another dashboard or for getting help or useful info. When you click on a panel, it opens the link either in the same tab or a new tab, depending on your choices. For example, if you want to compare a default dashboard, just click the link to open it.
The next section is the Tooltip which is used to show the details of a panel.
As you can see, there is a green-colored tip showing wherever you click on the graph.
The next option is the “Legend,” which essentially allows you to choose how you want the legend values to appear: at the bottom or on the right.
As for the Legend mode, you can show it as:
You can select a number of values such as Last, First, Min, Max, Total, etc to show in the legend.
The values are the specific properties of the data after the latest refresh.
For example, when “Last” is selected, the last received data for the selected time period is shown.
The corresponding properties of the data will be displayed as a legend in the graph.
The next option is the Axis from where you can configure all the axis settings of your graph.
The further options that you can configure in your axis settings are:
The Standard Options are used to configure the other standard settings in the graph. It changes the way the graph appears.
The further options include:
The Data Links option is similar to the Panel Link where you can link a URL and then open it in another tab. It is placed on the data instead of the Panel.
You can click on the data anywhere and the link option will appear.
It is used for an instant link that you want to appear anytime you click on the data.
The Value Mappings option allows you to find a certain value and wherever the value lies, the display text is displayed. If there is a similar value in the data, it highlights in the form of the color selected.
The Threshold option is used to define the value threshold. You can set certain thresholds and color-code them.
There are three options to show threshold mode:
For instance, for CPU usage, use green for 30, yellow for 40, and red for 50, enabling quick detection of threshold breaches and immediate action or error alerts.
Use the Add field Override option to modify existing fields. Overrides enable changes to field settings, same as the field options available in a particular panel, with the flexibility to select the target fields.
To add a field override, click on the Add Field Override button.
Select the Field type
Select a field type, based on the following properties:
You can add multiple fields overrides by repeating the same.
You have now learned how to configure the Line Chart, change the panel settings, and more. You can save and edit the panel later too.
