title: In Power BI how can I plot values of 2 or more columns on a line graph
body: <p>I have some timeseries data i.e value of voltage for every minute. It is stored in a database. I can plot this value using a Line chart. But now I have values from another table which is the allowed ranges of this voltage(I have this per min too..this is a sql view and I can change it to suit my needs.) I need to plot a graph with the actual value and the range data...so it would be 3 lines...2 constant(showing the max and min) and the actual value in the middle...In the Line graph, I cannot pull in multiple columns and plot the line. Is there any other visualization available?</p>
