I have created a simple Bar Chart in Chart.JS and all looks good. I now need to add a text box to the chart with rounded corners such as in the example below
I have tried the annotation plugin, but that only seems to add boxes and lines, not text. I don't want to overwrite defaults as I have several charts on my page, and only this one is to contain the text.
Is this possible?
Thanks

The chart legend doesnt fit in the vizualization. Therefore, pbi just adds a button.
Example: Button circled in red.
There is a way to remove this button and add a breakline ? So it can just keep going below.
Thx.
Unfortunately, this is not possible. If you want more control over chart elements, I recommend using Deneb.

In chart.js, is it possible to change the color of a chart (theme) by clicking a button?
Let's say I have buttons named 'dark mode', 'light mode' when I click 'dark mode' button, the chart color changes to dark color.
I can't find any example of it by googling.
You can make a new chart or update your chart with the new colors in the options or in your dataset. There's no function with changes all colors to a dark mode, you have to change all colors on your own.
I can't give you all the possible color options, there's simply too many. Just look at the docs or maybe here for a few examples. You can for sure change e.g. all the dataset and background colors.
I've been trying to add separator lines between rows in my grid. I tried using wx.Menu() with the AppendSeparator() method, however the wx grid can't add objects of type Menu. Is there any other way?
This is not supported by the grid widget. You could size a column or row such that it is skinnier than usual and change all the cells in that row or column to have a different background color. You might also be able to utilize a custom label renderer or cell renderer. See the wxPython demo for examples.
I'd like to change the default style of the list-view control's tooltips to balloon.
I first called ListView_GetToolTips() to get the HWND of the list-view's tooltips control, and then used GetWindowLongPtr()/SetWindowLongPtr() to add the TTS_BALLOON style.
I handle LVN_GETINFOTIP to customize the tooltip for the items (first column) in the list-view: the tooltip texts that appear for the first column items are actually a copy of the text of the third column. The other columns (subitems) are managed automatically by the list-view.
The balloon-style tooltips for the first column items seem OK; their stems are correctly positioned:
But the tooltips for the second column seem drawn wrongly, e.g. the balloon is drawn as if it was referred to a subitem in a row below the actual row pointed by the mouse cursor.
In the following picture, the "star" indicates the position in which the mouse cursor was when the tooltip appeared, but the tooltip's stem points to a row below, marked with an ellipse:
The strange thing is that the tooltips for the third column seem drawn correctly.
Is this a bug in the list-view control? (I'm using Windows 7.)
Or what am I missing here?
The ListView uses a tracking tooltip and positions it to unfold and reveal the hidden text in a column that's too small. It's not expecting its tooltip to be a balloon and so doesn't compensate for that.
You'd need to sub-class the tooltip itself, watch for TTM_TRACKPOSITION messages from the ListView, and adjust the coordinates.
Your second question - the shaded background comes from the system theme. You should be able to get it by calling SetWindowTheme on the tooltip (I'm not sure why the ListView disables themes for the tip).
