charts - Setting a fixed width domain for a TimeSeries plot in JFreeChart -


I have a dynamic timer chart in which some values ​​are added every 20 seconds, I plot the plot width like 30 minutes I want to say that the "30 minute canvas / plot" starts from the left hand side of my chart, until this whole plot is filled up. After every 30 minutes, I want to clear out the old data and show only the latest 30 minute data which means that at any point in time, my chart will only show the latest 30 minute data. I have already made the chart and have done great work, except that the initial domain boundary is fixed at the point where it started even after two hours.

get upper position after 30 minutes, then upper left lower downstairs and old upbound + 30 minutes Set new upbound?

I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
