How to plot a line plot for metrics published to cloudwatch at irregular interval? Currently these metrics are being denoted by different dots.

Hi, look at https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/graph_a_metric.html

8. (Optional) To change the type of graph, choose Graph options. You can then 
9. choose between a line graph, stacked area chart, bar chart, pie chart, or number.

I guess that you want a line graph.

Best,

Amazon CloudWatch does indeed plot the data points at irregular intervals if the data is published irregularly. However, to create a continuous graph rather than dots at each point, you may have to use some kind of interpolation between the points. This would essentially "fill in" the graph between the actual data points.

Here is a step-by-step guide to do this using AWS CloudWatch:

• Go to the CloudWatch console.
• In the navigation pane, choose Metrics.
• Select the custom namespace, and then select the dimension.
• Select the Graphed metrics tab.
• Update the Statistic and Period as necessary.
• For the Graphed metrics -> Graph options, select Line.
• Set Period to the lowest common multiple of your publishing intervals.

However, there's a caveat here. CloudWatch does not inherently support interpolation for metrics that are published at inconsistent intervals. While you can create a line graph, the line connections between data points may not accurately reflect the unseen data between the publish times.

For more complex visualization or interpolation needs, you might need to consider exporting your CloudWatch data to a more flexible data visualization tool like Grafana or even a data analysis toolset in Python (like pandas and matplotlib) or R.

Please note that the interpolation won't create real data; it will just guess what the values could be based on the nearby known points. It's a good way to visualize trends, but it's not a substitute for actual data.
