Multi variable scatter plot

Hi Community,

 

I have a dataset of shipping voyages with columns for Date, Port, Shipping company, loading time, discharge time, etc. 
One useful visual is a scatterplot with loading time and discharge time on the X and Y axis respectively, where each dot represents a single port. Power BI automatically averages the load/discharge time for each visit to a particular port to correctly place the dot, and the graph works perfectly with no issues. With this the end user can easily see which ports are the most and least efficient. 

 

I have a second graph which is identical in every way including scale, but each dot represents a shipping company rather than a port. This also works perfectally with no issues. 

 

What I want to do is combine these into a single chart where each port dot shows up as blue, and each company dot is red. I see these kinds of graphs all the time (example from 30 second google search included below), but it appears to be impossible on Power Bi. In each case, the category ('port', 'company') shows up in the 'details' field on the visualizations pane. I am able to drag the second catagory in, but rather than displaying all the data at once, this creates a two level graph where I can toggle between the two- which is not what I want. 

 

Given how often I see these kinds of graphs, I just can't imagine it's really not possible. What am I missing, or is there another visual I can download that allows this? 


Thanks so much in advance.

    Hi lushd ,

     

    Please try the following steps:

     

    1. Createa a new table with Legend type (Port and Company) for slicer.

    2. For dynamic Y-axis:

    Measure = 
SWITCH(MAX('ForSlicer'[Legend]),
"Port",CALCULATE(MAX('Table'[discharge time]),FILTER('Table','Table'[Port]=MAX('Table'[Port]))) ,
"Company", CALCULATE(MAX('Table'[discharge time]),FILTER('Table','Table'[Company]=MAX('Table'[Company]))))

    3. Create a rank measure for conditional formatting:

    For conitional formatting = 
SWITCH(MAX('ForSlicer'[Legend]),
"Port",RANKX(ALL('Table'), CALCULATE ( MAX ( ( 'Table'[Port]) ) ),,ASC,Dense) , 
"Company", RANKX(ALL('Table'), CALCULATE ( MAX ( ( 'Table'[Company]) ) ),,ASC,Dense))

    4. Add Port and Company to tooltips field.

    Or unpivot the table.
