I'm trying to implement my own metrics endpoint to show a time-series of values. I've successfully created my own prometheus format exporter, and signoz is configured to pull that data in. When I omit the timestamps from the prometheus format (so it looks like this:

name {} 3.0

then I get a horizontal line, so no time-series, just one value only. Then I put the timestamps in, like this:

name {} 3.0 1663923600

for example, then it successfully imports but when I try and create the dashboard it says "no data available"
