I just started with Power BI. I'm trying to plot a line chart with dates on the X-axis and the corresponding values of a EURUSD rates series.

What I did step by step is:

1. Imported a datasheet from excel with several series of FX rates (EURUSD, EURGBP, etc.)
2. Selected "Don't summarize" in Summarization for the series EURUSD.
3. Create a line chart, where I dragged & dropped "Dates" into the "Axis" field and my EURUSD series into the "Values" field.

But automatically, Power BI shows it as "Count of" instead of the values (It shows me I have more or less 260 values from 2018 till 2021 and fewer values for 2022).
