PS : You are using the roundSlider plugin and not uiSlider.

So, in accordance with the doc, you can modify your element by assigning it an id ("slider" in your example).

You should deffinitely use a cloud function to update the stock. Create a function onCreate and onDelete functions trigger. If users can change data you would also need to onWrite function trigger.

Depending on the amount of data you have you woould need to create a custom queue system to update the stock. Belive me! It took me almost 2 years to figure out to solve this. I have even spoken with the Firebase engeeners at the last Firebase Summit in Madrid.

Usualy you would use a transaction to update the state. I would recommend you to do so if you don't have to much data to store.

In my case the amount of data was so large that those transactions would randomly fail so the stock wasn't correct at all. You can see my StackOverflow answer here. The first time I tought I had an answer. You know it took me years to solve this because I asked the same question on a Firebase Summit in Amsterdam. I asked one of the Engeeners who worked on the Realtime Database before they went to Google.

There is a solution to store the stock in chunks but even that would cause random errors with our data. Each time we improved our solution the random errors reduced but still remained.

The solution we are still using is to have a custom queue and work each change one by one. The downside of this is that it takes some time to calculate a lot of data changes but it is 100% acurate.

Just in case we still have a "recalculator" who recalculates one day again and checks if everything worked as it should.

Sorry for the long aswer. For me it looks like you are building a similar system like we have. If you plan to create a warehouse management system like we did I would rather point you to the right direction.

In the end it depends on the amount of data you have and how often or fast you change it.

You can use route and define a function like

It is because, there is no case if it is NULL for HTTP_USER_AGENT you can modify:

1. Use df.brand.value_counts() to add a 'total_count' column to the df using .merge.
2. Use Boolean indexing to rename any 'brand' with a 'total_count' less than, .lt, 20.
3. Get the new .value_counts for 'brand', and plot a horizontal bar using pandas.DataFrame.plot with kind='barh'. If there aren't many brands, use kind='bar' and change figsize. kind='pie' can be used, but, while I like pi, and pieces of pie, I do not like, or recommend pie charts.
   • ^{The main purpose of using a pie chart, rather than a bar graph, is to visually indicate that a set of values are fractions or percentages that add up to a whole. This message comes at a considerable cost: Comparing values is more difficult with a pie chart than with a bar chart because is harder for the viewer to compare the angles subtended by two arcs than to compare the height for two bars. - Bergstrom, Carl T.; West, Jevin D..

To add each of the elements from data and add them to map i did this:

You can replace your 0 values with NAs, for example with, dplyr::na_if(0) on your dataframe:

I think you are forgetting to pass. the [stroke] input in your component.

Try passing it and it should do the trick for you.
