Show trend lines of the predicted features when hovering around a chart
I have a line chart that shows probability (y-axis) by date/time (x-axis) for one customer (Cust. ID). I have added predicted_feat_1, predicted_feat_2, and predicted_feat_3 as a tooltip which changes when i hover around different date/time. Now this is where I'm needing help: I want to add trend lines of the predicted features in the tooltip such as to see how the salary changes over time for one Cust. ID. Age and zip will mostly be constant for a customer, but it's okay. I want the trend line for all three predicted features next to the feature name in the tooltip. The trend line should change dynamically when I select a different Cust. ID. How can I achieve this?
If the trend line is not doable in the tooltip, can I display the trend in another chart? Like is there a clickable feature such that when I click on the predicted feature name in the tooltip, it'll take me to another chart which shows the trend line for that feature for one Cust. ID? Thanks!
