I think you have so many data points and that is why line chart is not giving good information. May be you can select top 5 banks etc to show in line graph.
I completely agree with @hafizsultan about paring down what is displayed. I would go with something like a “top 5 and others” approach. This is quite difficult to do from scratch, but in the thread below @nick_m wrote a really elegant DAX measure that should be relatively straightforward for you to adapt to your data.
From there, I really like the MAQ treemap bar chart for this type of visualization.
Just for the sake of illustration, here’s what it looks like with your data with a simple top 5 ranking approach (as opposed to the better “top 5 and others” approach discussed above). With the relevant detail info in the tooltip well, I think you now have a really attractive visual that provides a lot of information.
Great – glad that was helpful to you. Shout out to @nerminayoub1, who turned me onto that tree map custom visual which I like a lot, and use in my own reports now.
