The same data can be transformed and visualized in many different ways, depending on what gives you the most insight. At the end of this tutorial, you will understand how to format a line chart, clone a chart, and format a single value chart.
This tutorial is based on sample data that is being sent into trials created after May 28, 2015. If your trial or organization was created before that, then this does not apply.
This document assumes you know how to create a chart in SignalFx, apply one or more analytics functions, and save a chart to a dashboard. You can learn how to do that by reviewing Welcome to SignalFx - Part 1, Chart 1.
Create a chart
To get started, create a new chart and choose the transaction count metric, demo.trans.count, from among the three metrics we are sending to your organization:
Then, apply the sum:aggregation function and annotate the chart as desired.
The default chart style is a line chart, so to display as a line chart, simply save and close. Note that you can resize and move the resulting chart as desired.
Cloning a chart
To clone a chart, click on the chart settings menu, then select Clone chart.
You will see the chart builder view for a copy (clone) of the previous chart.
Display plot as a single value chart
Hover over the chart display selector and select Single Value.
Your plot should now be appearing as a single value chart with a sparkline to the left.
Change the refresh interval
Depending on the metric, you may want to change how frequently this single value chart is refreshed. (Refreshing too frequently is not recommended, as it can be confusing to see the values changing very rapidly.) In this case, we know that this data has a 1-second resolution, but we don’t need to see it updated more than once every 5 seconds, so we choose that in the Refresh Every dropdown menu.
Annotate your chart
Now that you have the metric displaying properly, it’s time to annotate it so that your chart will be understandable by other people who see it. To add a chart name and description, click into the Chart Name field and change it to something concise and descriptive, like ‘Total transactions’, then click into the Chart description field to provide more information.
Save your chart
To save, click on the Save and Close button in the upper right hand corner. The cloning functionality in SignalFx (which is where we started from) gives you an option to move the chart to a different dashboard when you save it. In this case, though, we just want to put it into the dashboard you started from, which is the default.
And that's it!
