Time series graph - Expressions causing spurious zeros

Bug Report
1

On certain time series graphs, we use expressions such as abs({{value}}), and {{value}}/1000.
Charts that include an expression like this have started generating zeros for any timepoint (based on the resolution settings) that does not have any actual data.
If we remove the expression, it just appears as a gap and the chart looks normal. With all the zeros generated between data points, it looks like this:

We have only noticed this behaviour quite recently. I don’t think the charts were doing this when we originally built the dashboards, though I’m not 100% certain.

We did have a change recently to how we evaluate those expressions so that we could allow for graphing string-type attributes. Let me look into this a bit and get back to you.

We have a fix on the way. Hoping to have it out this afternoon. Thanks for bringing this to our attention and apologies for the bug.

We just pushed out a fix … Can you reload your browser to ensure you have the updated code and verify that the time series graph is displaying as expected now?

Looks like you’ve fixed it :slight_smile:
Many thanks Dylan, the speed of your bug fixes continues to impress us :smiley:
