Line and Column Cluster chart

Thanks for the reply from DatawithDinesh , please allow me to provide another insight:

Hi, te7037 

Regarding the issue you raised, my solution is as follows:
 

Make sure that the data you're trying to assign to the y-axis is a number. PowerBI requires numeric data for the y-axis in the line chart. In particular, when the field you want to drag in belongs to a measure, and the return value of the measure is a Boolean value, a date, and a text, it is not possible to drag in the line y-axis.
 

Of course, you can also check that your PowerBI Desktop is up to date. Sometimes, bugs are fixed in newer versions.
 

Here's the version number I'm using:

It is recommended that you try to upgrade the version according to your needs to see if this can solve the problem, the following is the official link:
 Download Microsoft Power BI Desktop from Official Microsoft Download Center

 
 Of course, if you have any new ideas, you are welcome to contact us.
