Chart | HTML canvas-based pie | Chart library

Both Swing and JavaFX are single-threaded UI toolkits, and each has their own thread for rendering the UI and processing user events. Modifying Swing components and creating Swing windows (e.g. JFrames) must be done on the AWT event dispatch thread. Modifying JavaFX components must be done on the FX Application Thread.

Thus when you're working with both toolkits together, you have to be careful to delegate the appropriate actions to the appropriate threads. The Javadocs for JFXPanel have more details.

Here's a complete example which includes a slight re-working of your code and shows how to move the different parts of the code to the appropriate thread:

when using a calculated column for setColumns,
you can use a custom function, instead of the calc: "stringify"

the function will receive two arguments,
the data table and the row index.
the function should return the value to be displayed (the annotation).

The way I did was the following,

First we get the the time we want to remove from the dataset, that is 15:30:00 in this case.

Since the Datetime column is in the datetime format, we cannot compare the time as strings. So we convert the given time in the datetime.time() format.

rm_time = dt.time(15,30)

With this, we can go about using the DataFrame.drop()

df.drop(df[df.Datetime.dt.time == rm_time].index)

I think you want a column chart, like this

As your question said, you simply sort by the element at position 1

You have to provide both annotations as object in 1 array, not an array containing objects containing arrays, see example:

item here is a Map.

You need to pass children as a props to Cards, like this:

Try stripmode='overlay' option. It should produce the following.

Data points overlayed:
