QUESTION
Here's my csv file CSV
I'm trying to take the mean of columns "Angle Min" and "Angle Max" and then multiply every row in the resulting dataframe with the "Angle Conversion Factor" in cell D8. Likewise I want to do the same with "Torque Min" and "Torque Max" (get the mean and then multiply the resulting dataframe by the "Torque Conversion Factor" in Cell E8).
Here's my code so far:

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 using Visual Studio 2019 (Community edition) running on a Windows 10 machine. I have created a simple console application and I want to import the format module so that I can use something like std::format(). I get an error that 'cannot find header 'format' to import. My code is based on a book by Horton and van Weet titled 'Beginning C++ 20' which starts with two lines namely: import iostream (this is contained in angled brackets) followed by a line which says import format also contained within angled brackets. Maybe let me rephrase my question. The code generated by Visual Studio says #include iostream but does not allow me to #include format. So, when do I use #include and when do I use import?
...ANSWER
Answered 2021-May-23 at 00:59While waiting for MSVS support of std::format, you can use the fmt library that is the basis for the std::format. This can be found at https://github.com/fmtlib/fmt. It is compatible with the C++20 standard but does include additional features. Add the library to your source and use fmt::format instead of std::format. It'll be easy to convert this to std::format once fully supported.

I am working on plotting the minimums and maximumss of a set of data, plotted around the average, shown with the solid green line. The red line is a threshold value, I want to draw partcular attention to where the data crosses that line.
...ANSWER
Answered 2021-May-08 at 00:33The fill_between
method won't plot the bar at the transitions between True
and False
in the where
argument.
see: https://matplotlib.org/stable/api/_as_gen/matplotlib.axes.Axes.fill_between.html
Define where to exclude some horizontal regions from being filled. The filled regions are defined by the coordinates x[where]. More precisely, fill between x[i] and x[i+1] if where[i] and where[i+1]. Note that this definition implies that an isolated True value between two False values in where will not result in filling. Both sides of the True position remain unfilled due to the adjacent False values.
You could add a method to produce additional True
values for your where
argument. In the example below I've had to make some assumptions for what your data looks like, but the gapfill
function worked for the data I assumed.
QUESTION
Reported to Qt as a bug: https://bugreports.qt.io/browse/QTBUG-93475
I am re-drawing a QPixmap
multiple times in different locations, with differnt rotations by transforming the QPainter. In certain situations the QPixmap
is not drawing correctly. The GIF below shows my initial discovery of this issue with a QPixmap
containing a green cylinder, notice how the rendering behaves as expected to the left of the GIF, but there is a boundary beyond which the rendering is incorrect. The QPixmap
content appears to stick in place, and the pixels at the edge appear to smear out accross the rest of the pixmap. In the GIF there is a magenta background to the QPixmap
, this because the targetRect
used by QPainter::drawPixmap()
is also beuing used to seperately fill a rectangle underneath the pixmap, this was because I wanted to check that the target rect was being computed correctly.
To keep things simple I am simply filling the QPixmap
with magenta pixels, with a 1 pixel wide transparent edge so that the smearing causes the pixmaps to dissapear completely. It doesn't show the image "sticking" in place but it clearly shows the boundary as beyond it the pixmaps seem to dissapear.
I have been experimenting with this myself and I believe this to be entirely caused by the rotating of the QPainter
.
The angle of rotation seems to have an effect, if all of the pixmaps are rotated to the same angle then the boundary changes from a fuzzy diagonal line (where fuzzy means the boundary for dissapearing is different for each pixmap) to a sharp 90 degree corner (where sharp means that the boundary for dissapearing is the same for all pixmaps).
The range of different angles also seems to play a part, if the randomly generated angles are in a small 10 degree range, then the boundary is just a slightly fuzzier right angle, with a bevelled corner. There seems to be a progression from sharp right angle to fuzzy diagonal line as the number of different rotations is applied.

...ANSWER
Answered 2021-May-06 at 14:43This issue is very interesting. As far as I could test, your code looks good, I feel like this is a Qt bug, and I think you need to report it to Qt: https://bugreports.qt.io/. You should post a single piece of code to illustrate the issue, your second one from your "Update" edit is good: it makes it easy to reproduce the issu. Maybe you should also post a small video to illustrate how things are getting wrong when you zoom in/out or move the area with the mouse.
I tried some alternatives to hopefully find a workaround, but I found none:
- Tried to use a
QImage
rather than aQPixmap
, same issue - Tried to load the pixmap from a frozen png/qrc file, same issue
- Tried to use
QTransform
to play with scale/translation/rotation, same issue - Tried Linux and Windows 10: same issue observed
Note that:
- If you don't rotate (comment
paint.rotate(entity.rotation_);
), the issue is not visible - If your pixmap is a simple mono-colored square (simply fill your pixmap with a single color using
pixmap_.fill(QColor::fromRgba(0x12345600));
), the issue is not visible anymore. That's the most surprising, looks like a pixel from the image is being reused as background and messes things up but if all the image pixels are the same it does not lead to any display issue.
Workaround proposed by the Qt team
"The issue can easily be worked around by enabling the SmoothPixmapTransform render hint on the painter"
QUESTION
ANSWER
Answered 2021-Apr-27 at 00:25This happens because the area mark tries to interpolate linearly from where the blue and orange region ends to the bottom of the x-axis for each section of the area. If you set interpolate='step'
you will see that the border is sharp (removing impute
will improve it for the area). You can try to upsample the data to have the interpolation happen over such a small distance that it appears to be a straight vertical line and the areas look connected, more details in the answer to this question How to correctly shift the baseline in an area plot to a particular y location and change the fill color correspondingly, in Altair? .
Another solution is to layer the middle portion on top of the entire density plot:
QUESTION
This is probably quite a simple question, but I can't find an answer.
I'm trying to build an ActionSheet with two buttons (as well as a cancel button):
- Button "Select from Gallery" opens an
imagePicker
withsourceType
set to.photoLibrary
. - Button "Take a new picture" opens an
imagePicker
withsourceType
set to.camera
.
I've made the ActionSheet and the imagePicker successfully, but can't work out where to add the modifier to tell which sourceType should be used to each button. I managed to add it outside of the ActionSheet in a sheet()
modifier in a normal button like this and everything worked well:
ANSWER
Answered 2021-Apr-26 at 18:00Your question pretty much boils down to "How can I present multiple sheets?", so this thread might be helpful.
- Define a new
enum
to contain possible sheet types (gallery/take photo) - Declare a
@State
property to hold the current sheet type. It's optional because when it's nil, there will be no sheet presented. - Set the property to the type that you want
- Use
sheet(item:onDismiss:content:)
instead ofsheet(isPresented:onDismiss:content:)
.isPresented
is best for static sheets.item
is for when you have multiple sheet types, which is what you want.
