ng-tooltip | Smart and Flexible Angular Tooltip | Autocomplete library

(Edit: Please help guys I'm dying. This problem is not completely resolved, please refer to the comments)

I want to have the matTooltip show up only when the labels are actually overflown. like: when text is overflown, and when they are not, no tooltips.

Here is my broken code with trying to use matTooltipDisabled:

HTML (There are some code that I eliminated with "..." since I don't think they are necessary for the issue. Basically in the HTML, some labels will not be displayed unless you click on the dropdown, which is also a concern for tooltips):

I am trying to alter the tooltip in ggplotly. At the moment the tooltip is showing Data1 and reorder(Data2, Data1). I wish this to show Data2 and Data1. My approach is below.

In a Win32 / C++ app, running under 64-bit Windows 7, using Visual Studio 16.7.7, I want to implement tracking tooltips in the main (and only) window. Following the examples in Microsoft SDK documentation, the tracking seems to work, but the tooltip window itself does not appear.

I have verified, using the debugger, that the tooltip is activated and deactivated, that the expected mouse tracking is occurring, that the screen coordinates in the TTM_TRACKPOSITION message are correct, and the text is OK. The app is Unicode, and I have checked that the structures are the Unicode versions, and common controls are initialized, and that the current version of the common controls library is linked. The tooltip window has the WS_EX_TOPMOST and WS_EX_TOOLWINDOW extended styles, per Spy++.

What changes are needed to make the tooltip show?

Here is the code I am using:

Global variables:

I'm working with high charts in angular 7, and am wanting to format the date in just the x-axis tooltip, and I want to leave the others alone entirely.

I was able to get the formatting I wanted in the x-axis tooltip, but it also broke the other two. I have two series in the y-axis, and those we've formatted when inserting the series, but I've seen little to no documentation. The solution that formatted the one and broke the others was from this question:

SO Quesrtion with Datetime Tooltip formatting.

so I did my formatter like this:

Background: I am trying to add a tooltip to a react-native-svg chart following this tutorial. The link to the tutorial: Link

Current Code Implementation:

The view is loading before the data which is coming in from a call and being passed on to the directive in Angular 4.

I did some debugging but was unable to wrap my head around this thing, I guess issue is with the data not being present before the view getting loaded.

I using tooltip like in exemple Toggle Tooltip:

In the hunt for custom build hover messages, and making sure they stay on the screen I managed to fix the css position updating with this question: SO question, but in my real app, the nr op plots can be set by the user, who will be autoscaled: 1-20 plots 1-4 columns

On hover, both plots produce px values of vertical and horizontal position, and both plots seem to give similar values. This then triggers the calculation of offset correction depending on which part of the plot the coordinates are in (move up/down, left/right depending on which quarter of the plot)

I am trying to add a regression line to a scatter plot. I am using the below code as an example for scatter plot. http://bl.ocks.org/majetisiri/57da501b3182bd08d17402261c7187f7

I am appending the path to svg as explained here: Plot regression line on a scatter plot from regression coefficients

But the regression line is not visible.
