Catching Correct Value Issue with Hovering Functionality in Line Chart

Hi Everyone,


I have an issue about showing values correctly on the line chart. X-axis includes date-time values and y-axis includes values.

When we move the mouse on values, it means that we are not hovering on the points, we are hovering on the line since we changed the colors of the lines as white.


We can see an example below not corresponds to 0 value but equals approximately to 1,024.



The same issue is continuing even if we narrow down both date and values sliders as is seen from below screenshot.



Even though the points seem there is only one value on it, there can be more than one values look like one point.

That's why when we are hovering the line (bc actually not the point),  we are selecting the wrong point.



Finally, if we make a filter by creating a slider with ‘value’ column, we can see the correct values on chart as shown in below. However, I am looking for a better solution by not creating another visual to see correct value and points when hovering the mouse on them.



As a note, I am using Azure Synapse connection on Power BI with DirectQuery to get live data from database. 


Is there any idea about how can it be fixed?

Many thanks in advance!

I think your X Axis has a lot of items (you define your time at unit of second), so when you hover, maye system will define wrong line.

try to edit Width in X Axis to create space that you can hover right line.


Any way, you narrow the Y axis scale, that mean it only show items belong to scale, but other items still be in chart but invisiable. Only you add new slicer, that is true filter.
