问题描述
在Power BI中可视化我的输出时遇到了麻烦。我已经导入了超过1500个CSV文件，但是每次可视化时，它仅显示从1500个CSV文件中随机选择的10个CSV文件。
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.

我如何一次看到所有1500个CSV可视化图像，而不仅仅是10个CSSV？
How can I see all 1500 CSV visualization at once rather than just 10 CSSV?
如果不可能，那么我想知道如何从1500个CSV文件中选择10个CSV文件？是否需要进行任何计算，或者仅仅是Power BI自行选择剂量的随机选择？
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?
在image4中，我想知道计算结果如何=平均值，总和，中和最大值。
In image4 I would like to know how the calculation is di=one for Average, Sum, Medium, and Maximum.
我附上了屏幕截图供参考。我尝试使用各种过滤器，但没有一个给我想要的输出。在Image4中，您可以看到我可以选择Sum Average Minimum Maximum和其他过滤器....但均不起作用。
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.
推荐答案
Power BI可以在图形上打印的数据点数量受到限制。
自一月以来，您可以使用高密度折线图获得更多选择。
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.
