See Points Value When pointing mouse on it

Post by AxelDorian » Mon Apr 24, 2017 1:32 pm

Please I want to know if it is possible to place the mouse on a point and see the value that point?
If possible how can I do it?

Hi Axel,
LightningChart supports several ways to solve data points, under mouse, or specific location. It also has tools to solve multi-series values from gigantic data sets.

In many series types, there's SolveNearest*** methods to solve nearest data point to given (x,y) value, or screen coordinate.
Please see "Cursor tracking" examples in the v.8 demo app.

Here's one which solves nearest scatter point and shows its value in Annotation.
