history() allows you to set the auto_adjust=False parameter, which deactivates adjustments on OHLC (Open/High/Low/Close prices). By default, adjustments are enabled.

For download() adjustments are disabled by default.

If disabled for history(), both variants lead to the same result:

There are two entirely separate getline()'s. One is std::getline(), which takes a std::string as a parameter.

But there's also a member function in std::istream, which works with an array of chars instead of a std::string, eg:

It depends on how you want to scale it. If you just want the percentage you could just use Float.greatestFiniteMagnitude as the maximum value.

All the code after the closing brace for your featureprintObservationForImage function is not inside any function or closure. You can't do that. (That code is not just variable decalrations. You have function calls, which is not legal outside of a function.)

You can create something called computed properties, where you provide a closure that gets invoked each time you read a value from the property.

I want to group using Grade and sort in descending order based on the number of elements in each group, then use the Number property to sort each group element in ascending order.

That's not what ThenBy is for. ThenBy provides a secondary ordering for the same sequence. It's not meant to perform a sort within items in the sequence. (Additionally, the last part of your lambda expression in ThenBy is List.Sort, which returns void... whereas the compiler expects a delegate that returns "the thing you want to perform secondary ordering by".)

The "outer sequence" ends up being a sequence of groups. If you want to transform each of those groups, you need to use Select. So I suspect you want:

I wouldn't remove anything from dataset. Instead I'd build a new map from scratch, with just the data you want.

How about:

The error message EADDRINUSE is telling you that you already have something listening on port 3000. You need to stop the process/application currently using port 3000 so you can run MUI docs or tell MUI docs to use another port.

You can do one of the following:

• Tell MUI docs to run on a different port: yarn docs:start --port=3001 (This is probably your best option.)

• Look for the application (probably another terminal window -- your other React app?) and stop it (Ctrl + C)

• Reboot your machine and make sure that nothing starts up listening on port 3000.

• Find the process id in terminal and kill it manually.

To find the process id in terminal and kill it manually, open up terminal on your Mac and type the following commands:

Get a list of any processes listening on port 3000 (sudo will require you to enter your password)

As stated in the comments by @jewelsea, your model class (Apple) should contain only data; it should not contain UI fields such as ImageView. Any Node can only appear once in the scene graph, which is why you only see the ImageView in a single row in the table.

You should instead store either the path to the image, or the Image (which is only data) itself in the model class. The trade-off between these two choices is a compute-time versus memory consumption trade-off. If you store the path to the image, the image will need to be loaded each time a cell updates (e.g. during scrolling), which takes time. On the other hand, if you store the Image, then all images needed for the entire table will need to be stored in memory, whether or not they are displayed.

I would recommend storing the Image in the model class if your table only needs a small number of images. This may happen if the table only has a few rows, or if there are a small number of images and multiple rows show the same image. Note that Images can be shared by multiple ImageViews, so there is no need to load any single Image more than once.

Using Image in the model class would look like this:
