Editing charts¶

1. Editing a chart¶

Click on the three dots ... on the Latency histogram chart in the Sample Data dashboard and then on Open (or you can click on the name of the chart which here is Latency histogram).

You will see the plot options, current plot and signal (metric) for the Latency histogram chart in the chart editor UI.

In the Plot Editor tab under Signal you see the metric demo.trans.latency we are currently plotting.

You will see a number of Line plots. The number 18 ts indicates that we are plotting 18 metric time series in the chart.

Click on the different chart type icons to explore each of the visualizations. Notice their name while you swipe over them. For example, click on the Heat Map icon:

See how the chart changes to a heat map.

Click on the Line chart type and you will see the line plot.

2. Changing the time window¶

You can also increase the time window of the chart by changing the time to Past 15 minutes by selecting from the Time dropdown.

3. Viewing the Data Table¶

Click on the Data Table tab.

You now see 18 rows, each representing a metric time series with a number of columns. These columns represent the dimensions of the metric. The dimensions for demo.trans.latency are:

• demo_datacenter
• demo_customer
• demo_host

In the demo_datacenter column you see that there are two data centers, Paris and Tokyo, for which we are getting metrics.

If you move your cursor over the lines in the chart horizontally you will see the data table update accordingly. If you click on one of the lines in the chart you will see a pinned value appear in the data table.

Now click on Plot editor again to close the Data Table and let's save this chart into a dashboard for later use!
