QUESTION
I am trying to produce an animated choloropleth map to detail the spread of the coronavirus through a csv file in JuypterLab. I got the map to output, but not only are the dates wrong, but the map does not animate and is a static image. I tried changing the renderer and some of the values, like in this line of code, but it still does not produce the correct result.
...ANSWER
Answered 2021-Jun-08 at 06:30The choropleth map can be specified only with px.choropleth(). The data was obtained from here and recalculated to create data in years. This is because animation in days is very slow. Also, the slider is a numeric string, so I converted it to a string and sorted it.
QUESTION
I've been running into this same problem for the last few days, googling everything and searching for answers on this forum, but nothing I'm trying is seeming to work. I've been following tutorials other people have posted and they're able to do this very simply, but I run into multiple problems when I try it from multiple angles. I've got my head so tangled up from all the things I've tried that I'm not even sure what's happening or what I've done anymore. This isn't all of the code, but this should be the only relevant code because the other parts do other functions, but I apologize if I missed anything.
Basically, I'm grabbing historical financial candlestick data from a website, trying to put it into a Pandas dataframe, and then use that dataframe to make charts with Plotly. I get the data as 'result', PyCharm outputs the data just fine into the 'Run' box, but now I need to save that data, so I have Pandas turn 'result' into a dataframe as 'priceData', and convert that to 'pricedata.csv'. When I open that CSV file, all I get is a list from 0 to 1439 (I'm importing 1440 1 minute candlesticks at a time), and each candlestick only shows the object reference (, or similar). That's obviously not what I'm after, I need the data within the candlesticks, which should be made up of 12 pieces of data (open time, open, low, close, high, etc...). When the chart function runs, it comes back with "AttributeError: 'DataFrame' object has no attribute 'high'", which I assume is because it's accessing that candlestick object ID and not the values.
I can get the specific values by going in-depth, and calling for it to save result[0].high, or result[0].low, etc. But then I have to iterate through 1440 candlesticks of data and write/save them all separately, and then bring together the high/low/open/close/time/etc of each of them to be able to plot, which is far more complicated than what the tutorials I've watched do. They're able to literally just use the dataframe right away to plot with no troubles, they don't run into the attribute error, it's like it just identifies the columns correctly for them. But when I look at the columns of 'result', there's 1440 columns (again one for each candlestick), but I would think it should be 12 columns for the 12 different bits of data each candlestick is made up of. I've tried transposing the columns and rows, but that doesn't work either.
Even if I try to get the whole candlestick data for just one object, by specifying "result[0]" without specifying the .high/.low/etc, I run into the same attribute error. Some things recommended to specify what the columns are, so that's what the hashed out "priceData.columns" is for, where I identify what each column is. But then I get "Length mismatch: Expected axis has 1440 elements, new values have 12 elements".
I'm really confusing myself and going in circles at this point, can anyone help point me in the right direction and tell me what I'm screwing up on? Thank you in advance to anyone who takes the time to even read this, or has any direction they can offer.
...ANSWER
Answered 2021-May-27 at 06:21The way you are currently getting the candlestick data, result is a list of Candlestick objects, and each object has attributes that can be individually accessed, such as result[0].high as you pointed out. It sounds like you want to unpack all of these attributes and put them into a DataFrame.
To obtain all of the attributes of an object, such as all 12 attributes of the Candlestick object in a dictionary, you can use result[0].__dict__ which returns: {'openTime': 1609473600000, 'open': '29302.11', 'high': '29356.04', 'low': '29302.10', 'close': '29344.00', 'volume': '170.018', 'closeTime': 1609473659999, 'quoteAssetVolume': '4988200.62513', 'numTrades': 1045, 'takerBuyBaseAssetVolume': '139.291', 'takerBuyQuoteAssetVolume': '4086412.01157', 'ignore': '0'}
To get a list of these dictionaries from result, you can use a list comprehension: [candlestick_obj.__dict__ for candlestick_obj in result], and pd.DataFrame allows you to construct a DataFrame from such a list of dictionaries so priceData = pd.DataFrame([candlestick_obj.__dict__ for candlestick_obj in result]) will create a DataFrame with columns for the keys in each of the dictionaries with 1 row for each list item.

QUESTION
I am trying to use separate files for my PlatformIO Arduino project, but I get this error:
...ANSWER
Answered 2021-May-22 at 16:53You appear to have two source files in your project: main.cpp and test.cpp. Both are probably including test.hpp. So now each source file has independently picked up a value variable. So the linker gets confused because it doesn't know which value each module should use. And you probably do not want multiple instances of this global variable. You just want a single one.
Do this instead in test.hpp:

This is not a duplicate of this.
Adding the makes sure the trace# is removed from the graph. But is there a way I could make that the default setting?
I am creating a custom plotly theme and would like it to be the default setting, but it is included in the trace class and not the layout one. Also, adding it to every trace call in plotly.go call is repetitive.
To recreate the graph-

Answered 2021-May-22 at 15:42Interestingly enough, I found a solution that does the trick!
Passing hoverlabel = dict(namelength=0) to the trace calls removes the trace#. Same can be implemented by passing it in the template. Here's the complete code-
QUESTION
I have a class like this :
...ANSWER
Answered 2021-May-19 at 11:25Your problem is related to staticvariables. The rules for static and therefore also static constexpr variables depend on the particular C++XX standard being used. If the class members are not declared static constexpr the code will work from C++11 on-wards while with it it will only work like this for C++17 and later. For versions prior to C++17 you will have to supply additional out-of-class-definitions.
The standard for static constexpr class members has changed over the years:
Prior to C++17 any
staticclass members did not have a location in memory until the variable was defined outside the class. This way one might define it at some other place, in another source file or a library. If it is used you needed to provide an out-of-class definition.
QUESTION
I'm fairly new to Plotly Dash and I'm trying to create a simple Dash app. In this app, I'm trying to display a plot that changes when the value in the dropdown menu is changed. The values are the boroughs in London. Below is the code for base plot.
...ANSWER
Answered 2021-Feb-14 at 19:18You can create a copy of your data frame containing only the data corresponding to the dropdown selection, and then use this filtered data frame for generating the figure. See the code below for an example.
QUESTION
I am integrating a library (lwip) and I want to reroute the logging mechanism from printf to something I wrote myself (which logs directly to my uart).
In some header file the following code exists
...ANSWER
Answered 2021-May-14 at 14:15extern "C" void logLineToUart(const char * log, ...);
You need to tell it to make the name C-linker compatible the first time it is seen.
updateThe extern "C" is only when compiling as C++. It is not legal syntax in C. You can use extern by itself (it is implied if you leave it off).
That's not very friendly... C++ accommodates sharing header files with C by accepting syntax that would not apply to C++, just to make it easy to use the same header file contents. In particular, using (void) for empty parameter lists (which is "an abomination") and allowing a comma in variadic function parameter lists ( (int x ...) is how C++ originally defined it; when the same feature got incorporated into ANSI C they used (int x, ...) with a superfluous comma that is not needed by the grammar.) C++ compilers accept both of these to make it easier to consume C headers...
But, you have to add extern "C" around everything. This introduces conditional compilation anyway, even though C++ accepts the C syntax. Note that for a single declaration, extern int foo (int); the extern is allowed and implied if you leave it out. If the C compiler allowed the linkage specification even though only "C" is available, it would make life easier. Note that in most cases, the C and C++ implementation are the same compiler suite, and often one language supports some features of the other as extensions. It would be cool if gcc etc. supported extern "C++" in C mode, since that code base certainly does know how the name encodes the parameters.
