This was a bug fixed in 0.14.0 (coming next week), see here: http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0140-api (the set_index section). You can get the pre-release here: https://github.com/pydata/pandas/releases...

You could construct a mask -- a boolean array which is True where the Series index equals the particular value: mask = my_series.index.isin(['intercept']) Then you could select the remaining rows in the typical fashion: my_series.loc[~mask] Note that if the value occurs in the index more than once, then all rows...

python,string,list,pandas,series

You are basically just trying to flatten a nested list here. You should just be able to iterate over the elements of the series: slist =[] for x in series: slist.extend(x) or a slicker (but harder to understand) list comprehension: slist = [st for row in s for st in...

This is the Taylor's series development of exp(-x). Recognizing this gives you a good opportunity to check your result against math.exp(-x). Simple syntax improvements You don't need an 'else' after the while. Just add the code to be run after the loop at the same indentation level as before the...

Ok, got it going finally. One has to pass the JSON as an object (and not an array, and neither as string (so, no quotes like ' or " around the object!). Works like a charm here on fiddle. Here the code: $(function () { var options = { chart:...

You could loop over each string in each row to create a new series: pd.Series([j for i in s.str.split('\n') for j in i]) It might make more sense to do this on the input rather than creating a temporary series, e.g.: strings = ['This is a single line.', 'This is...

it should be: In [32]: grouped = df.groupby("student_id") In [33]: grouped.filter(lambda x: x["student_id"].count()==1) Updates: i'm not sure about the issue u mentioned regarding the interactive console. technically speaking in this particular case (there might be other situations such as the intricate "import" functionality in which diff env may behave differently),...

Presumably your factorial function, which you're not showing, is performing integer arithmetic. After 12! you're going to overflow a 32-bit integer. Switch to using double in the factorial function too.

python,pandas,dataframes,series

You could do so with some nested list comprehension, followed by an application of pandas.DataFrame.from_records: import pandas as pd records = [tuple(f(A, O) for A in AP) for O in OP] pd.DataFrame.from_records(records) ...

Don't use apply you can achieve the same result much faster using 3 .loc calls: df.loc[(df['column_of_ints'] >= 0) & (df['column_of_ints'] < 100), 'column_of_ints_v2'] df['column_of_ints'] df.loc[(df['column_of_ints'] >= 100) & (df['column_of_ints'] < 200), 'column_of_ints_v2'] = df['column_of_ints'] + 1 df.loc[(df['column_of_ints'] < 0) & (df['column_of_ints'] >= 200), 'column_of_ints_v2'] = df['column_of_ints'] + 2 Or using...

The main issue with your code is that you are using a Select Case when you seem to just need a simple If. The corrected code for that is Sub exmpl() Dim MySeries As Series ActiveSheet.ChartObjects("Chart 3").Activate For Each MySeries In ActiveChart.SeriesCollection If MySeries.Name = "NotThisSeries" Then ActiveChart.SeriesCollection(MySeries.Name).IsFiltered = True...

If you take two data points (a and b) you can use the equation of a line to get Y for any X point (or X for any Y point) between them: public static int GetX(int y, Point a, Point b) { var m = CalculateSlope(a, b); // Horizontal line...

The general idea should be that for each series you set it's id. Then you cna get that series this way: chart.get(id). So if you have series, then add point to that series, if not, then create new one, just like this: http://jsfiddle.net/9FkJc/8/ var self = this; data = [{...

If the date column has dtype datetime64[ns] and the time column has dtype timedelta64[ns] then you can add them together to form a new column of dtype datetime64[ns]. Then you could set that column as the index and select the frequ column to obtain the desired Series: import pandas as...

No one gave the mathematical approach, so I am adding the mathematical approach to this AP problem. Given series is 1k + 2k + 3k + .... + k.k(OR k^2) Therefore, it means that there are altogether k terms together in the given series. Next, as here all the consecutive...

Here is a little workaround to do it with alpha-sections: private void SetChartTransparency(Chart chart, string Seriesname) { bool setTransparent = true; int numberOfPoints = 3; chart.ApplyPaletteColors(); foreach (DataPoint point in chart.Series[Seriesname].Points) { if (setTransparent) point.Color = Color.FromArgb(0, point.Color); else point.Color = Color.FromArgb(255, point.Color); numberOfPoints = numberOfPoints - 1; if (numberOfPoints...

python,pandas,indexing,dataframes,series

The reason that it is converting the indexes to strings is because the last index intercept [-11.4551819018] in your series data is a string. The documentation for the Pandas data frames state that when constructing a data frame from a series the data frame keeps the same indexing from the...

If you use .FormulaR1C1 = Replace(.FormulaR1C1 , "A", L) instead of .Formula = Replace(.Formula, "A", L) the '1004' goes away. Beats me why but it's alway worth trying when '.formula' results in an error. You'll still have to put some thought into the positioning of the charts though. Currently they...

As I'm not sure of what values you are binding, it would be better to capture all values above and inclusive of your maximum. I suggest changing your first IF statement to: if (c.Series[s].YValuesPerPoint >= 255) c.Series[s].Color = Color.Red; ...

Try this: d = dict() column = list() for _, a, b in df.itertuples(): if b != '0': d[a] = b else: d.pop(a, None) column.append(d.copy()) df['C'] = column ...

If you can't run the code, you can look at the for loops: for(int i = 0; i < n-1; i++) for(int j = i+1; j <= n; j++) The first loop runs n-1 times. The second loop runs n-i-1 times (for each i). So the total loop runs is...

In case there is any other poor ghost out there which needs this info... It seems like a dirty work-around, but it works: # add() works for mutual indices, so find intersection and call it # fortunately, it appends list2 to list1! intersection = series1.index.intersection(series2.index) inter1 = series1[series1.index.isin(intersection)] inter2 =...

If all functions are in order, you could add all of your functions to an array: var functions = [function_zero, function_one, function_two, wrap_up]; and then execute them with for example the async module as follows: async.series(functions); The benefint of adding them to an array is that you could slice the...

You can add them (if you first multiply the hours by the number of nanoseconds), but you have to drop down to numpy to do the calculation*: In [11]: dr = pd.date_range('2014', periods=5) In [12]: hours = pd.Index(np.arange(5)) In [13]: pd.DatetimeIndex(dr.values + hours.values * pd.offsets.Hour(1).nanos) Out[13]: <class 'pandas.tseries.index.DatetimeIndex'> [2014-01-01 00:00:00,...

i and fact(i+1) are both ints, so you're performing integer division. Since i < fact(i+1), each such term will produce a zero. You had the right idea with defining sign as a double, but since / and * have the same precedence, you're first performing an integer division and only...

You probably have wrong X-Values for the purpose. Note that your Series can only stack where DataPoints have the same X-Value. DateTimes include times downto fractions of a second, so they will never stack unless you twist them to meet your goal.. You code is closely missing the point here:...

It sounds like you need to use groupby for this together with cumsum since you want a running total: cum_defaults = df.groupby('time_to_default').default_amnt.sum().cumsum() You then need to reindex this new series to fill in any missing days: cum_defaults = cum_defaults.reindex(index=range(min(cum_defaults.index), max(cum_defaults.index) + 1), method='ffill') With some example data: df = pd.DataFrame({'time_to_default':...

This assumes that you want to do some sort of interpolation between points if the two series do not have the same number of points. A simple linear interpolation should work for a sufficiently large number of points, and so the whole algorithm could look something like this (in pseudo-code):...

The colors are assigned automatically according to a palette, unless a color has been set explicitly. So the next series down gets the freed up color. To avoid this, you need to explicitly set the colors of all series. See http://msdn.microsoft.com/en-us/library/system.windows.forms.datavisualization.charting.series.palette(v=vs.110).aspx...

This will do what you want: =INDIRECT("B"&(17*(ROW(C5)-5))+5) Indirect allows us to construct a string of text to represent an address. We are taking the row it's on and taking away 5 then multiplying the result by 17 then adding 5. On row 5 this will be 5-5=0 * 17 =...

You were almost there. You needed to check the api for the shared tooltip formatter. Put your check for the series you do not want inside the for each: ... tooltip: { formatter: function () { var s = '<b>' + this.x + '</b>'; $.each(this.points, function () { if (this.series.name...
