Helper ILine is shrinking on Line Chart when many values are included
Community SupportHi rcheskin ,
For a high-density visual, Power BI intelligently slices your data into high-resolution chunks, and then picks important points to represent each chunk. That process of slicing high-resolution data is specifically tuned to ensure that the resulting chart is visually indistinguishable from rendering all of the underlying data points, but much faster and more interactive.

Helper IHi v-deddai1-msft , if you read my post then you would know the resulting chart is obviously visually different because the minimum value is no longer represented.

Hi rcheskin ,
In my understanding, for a high-density visual, Power BI intelligently slices your data into high-resolution chunks, and then picks important points to represent each chunk. The points picks in your situation is not the minium value. So it didn't show any more. It should be the default for Power BI, I didn't find any option for it.

v-deddai1-msft It is the minimum value for the x-axis (20 Hz), not literally the minimum for the "Values" in the Power BI Line Chart.
