When I am writing code in Python, I often need to remove items from a list or other sequence type based on some criteria. I haven't found a solution that is elegant and efficient, as removing items from a list you are currently iterating through is bad. For example, you can't do this: for name in names: if name[-5:] == 'Smith': ...
I have an instance of a WMEncoder class THis is .NET so basic interop , what I mean is the WMEncoder is actually generated by the runtime like so namespace WMEncoderLib { [Guid("632B6081-BBC6-11D2-A329-006097C4E476")] [CoClass(typeof(WMEncoderClass))] public interface WMEncoder : IWMEncoder2, _IWMEncoderE...
Suppose I had a set of alpha-character identifiers of a set length, e.g. always five letters, and they are assigned in such a way that they are always incremented sequentially (GGGGZ --> GGGHA, etc.). Now, if I get to ZZZZZ, since the length is fixed, I must "roll over" to AAAAA. I might have a contiguous block from ZZZAA through AAAA...
Hi, is it possible to make a series in a chart optional (i.e. only rendered when the user clicks a checkbox, in case the corresponding query takes a while and may not be required)? Or are there any alternative solutions where users can incrementally select the data series/charts they would like to see? ...
Hello all, I have a Flex bar chart with two data series in a clustered format. The series are called RequiredFunding and ApprovedFunding, so they're plotted next to each other. The problem I am having is trying to format the label function on the Funding axis. I have several thousands of dollars being displayed and it needs to be for...

I have written a program in C# whereby it automatically generates a graph for me from a CSV file and puts it onto a new XLS file. However, I need to change the color of the Line (as it is a Line Chart) to red rather than the default blue. I am finding this extremely difficult to do and the stuff I've found online has not worked. Please ...
I have this problem I can't quite solve. I can get the missing numbers interval, but I can't piece them back together to from my continous series. So if I have a series defined as [1000,1001,1002,1003,1005,1006,1008] I want to extract the three continuous series [1000,1001,1002,1003] and [1005,1006] and [1008]. Using a simple CTE I got ...
I need help programatically graphing more points than can fit in a single Excel series. According to http://office.microsoft.com/en-us/excel/HP100738491033.aspx the maximum number of points displayable on an Excel 2007 chart is 256000. Given that each series caps out at 32000 points, 8 series are required to plot the full 256000 points...
Hello All, Please can someone help me with this as it's driving me nuts! I'm creating an excel chart using C# and the COM interface pragmatically. I've created the chart using the chart wizard. I want to then add more series to this chart. I can add the series but the extra data is on new columns and they are not automatically create...
Can someone give me an idea of an efficient algorithm for large n (say 10^10) to find the sum of above series? Mycode is getting klilled for n= 100000 and m=200000 #include<stdio.h> int main() { int n,m,i,j,sum,t; scanf("%d%d",&n,&m); sum=0; for(i=1;i<=n;i++) { t=1; for(j=1;j<=i;j++) t=((long long)t*i)%...
I have a series of data points (tuples) in a list with a format like: points = [(1, 'a'), (2, 'b'), (2, 'a'), (3, 'd'), (4, 'c')] The first item in each tuple is an integer and they are assured to be sorted. The second value in each tuple is an arbitrary string. I need them grouped in lists by their first value in a series. So give...
please help to print series as well sum of series like 1*3-3*5+5*7 up to n terms i have used code like this in php class series { function ser(){ $i = 0; $k = 3; $m = 0; for($j = 1; $j < 3; $j++) { if($j % 2 == 0 ) { $m = $i + ($i * $k); } else { ...
Hi guys, Is there a way to set a rollover color for each series in a chart? For instance, I have a column chart with two series: one series is set to blue and the second series is set to gold. When the user mouses over the blue series, I would like the blue to turn to bright blue. And when the user mouses over the gold series, I would...

Also each category may have different number of bars. How it can be achived using Jfreechart library? Following image is the sample of what I require....
Hye Guys, I'm busy working on a time series and am trying to find the commands that allow me to insert a quarter count variable. To keep things simple, the third quarter of 1995 (date my observations start) should be quarter -2, the fourth quarter of 1995 should be -1 etc etc uptill 2006 (should be somewhere around 45 by then). My dates...
Which programming language or a library is able to process infinite series (like geometric or harmonic)? It perhaps must have a database of some well-known series and automatically give proper values in case of convergence, and maybe generate an exception in case of divergence. For example, in Python it could look like: sum = 0 sign =...
I have a sql query based report that returns multiple rows - typically 5 - each one having different values in the main data columns (8 off) and a column called type. Effectively for each different type there will be a different set of values in the corresponding 8 values columns. The report works perfectly but I cannot get more than one...

Hi, I have a question about how to assign property of a multi-layer object to Chart's xField or yField. For example: var obj:Object = new Object(); var store:Object = new Object(); store.store1 = 300; store.store2 = 200; store.store3 = 250; obj.date = "2010/04/26"; obj.count = 2; obj.store = store; Because I have t...
