问题
I had a trouble visualizing my output in Power BI. I have imported more than 1500 CSV files but every time I visualize it, it only shows 10 CSV files that are randomly selected among the 1500 CSV files.
How can I see all 1500 CSV visualization at once rather than just 10 CSSV?
If it's not possible then I wanted to know how is 10 CSV files selected out of 1500 CSV files? Is there any calculation involved or is it just a random selection that Power BI dose on its own?
In image4 I would like to know how the calculation is di=one for Average, Sum, Medium, and Maximum.
I have attached screenshots for reference. I tried using various filters but none has given me the desired output. In Image4 you can see that I can select the Sum Average Minimum Maximum and other filters....but neither worked.

Power BI has a limit in the number of datapoints it can print on a graph. since january you have more options with the high density line charts.
you can read more about it here: high density sampling
