When you create visuals, Power BI Desktop aggregates your data into groups, based on the values that it finds in the underlying data. You can refine how those default groups are presented.

You can also create new groups by grouping two or more data points in a visual or putting values into equal-sized groups (binning).

If you have categorical data,then either use a bar chart if you have more than 5 categories or a pie chart for less than 5 categories.

If you have nominal data, use bar charts ; histograms if your data is discrete ; line/ area charts if it is continuous.

If you want to show the relationship between values in your dataset, use a scatter plot, bubble chart, or line charts.

If you want to compare values, use a pie chart — for relative comparison — or bar charts — for precise comparison.

If you want to compare volumes, use an area chart or a bubble chart.

If you want to show trends and patterns in your data, use a line chart, bar chart, or scatter plot.

Import in Power BI :

A copy of the data from the selected tables and columns imports into Power BI Desktop. As you create or interact with visualizations, Power BI Desktop uses the imported data. To see underlying data changes after the initial import or the most recent refresh, you must import the full semantic model again to refresh the data.
