javascript - NVD3 Cumulative line chart displays wrong y values -

-

I have converted a line chart to the cumulative line chart and its y values ​​are not displayed properly. The Y axis range should be 80.00 - 140.00 but instead I get -0.08 - 0.20. Has anyone managed to work with all types of categories under its normalization code? {'Y': (lines.y () (point, point index) - v) / (1 + v)}; Return point;})

Any help will be greatly appreciated.

I know that this question is some old, but I believe that the normalization code for the cumulative line Chart is not conceptual right; In addition, the NVD 3 cumulative line chart implementation is actually an index chart implementation (), I think it would be more like a cumulative line chart, I think. Cumulative charts can easily be achieved using the NVD3 line chart and some quick modifications in the underlying data.

If we take Bostoncan correctly, and we really want to get the indexed line chart, then the indexed function in NVD3 should be changed: 

  / * index Making data normal by the point * / Function index (idx, data) {if (! IndexifyYGetter) indexifyYGetter = lines.y (); Return data.map (function (line, i) {if (Line.values) {return line;} var indexValue = line.values ​​[idx]; if (indexValue == null) {return line;} var v = IndexifyYGetter (IndexValue, idx); // TODO: Implement the check below, and disable the chain, if Series 1 is divided by 1, then ((Math.abs (v) & lt; 1e-6) Amp; amp;; no! // PS You may have to set a high threshold (~ 1e-6?) // I do not know that I did not run any tests ... line.tempDisabled = True; return line;} line.tempDisabled = false; line.values ​​= line.product.map (funk Return point;} return line;}}}    {index} Pre> 
 I asked the authors of NVD3 and planned to submit a bridge request.  Note that the percentage change chart is actually only meaningful when all the underlying data is positive when you mix negative Start throwing values, then change percentages Loses sense.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
