java - What are some good Statistic Visualization frameworks/libraries for user data? -

-

we've been collecting user data on our site while , we'd present data in accessible way.

we have database full of data, we're looking framework can dump our data , able visualize it.

some requirements:

  • must able sort & filter multiple dimensions (eg: user, action type, date, meta data)
  • must able export views of data csv/xml files
  • must presented through web interface (no desktop applications)
  • should usable either scala, java, python or ruby

we've looked @ using vaadin, , enjoy amount of control can have, i'd explore other potential solutions.

are there suggestions frameworks might display our statistics?

i'm having lot of joy working google visualisations , java library google provides. wrote adaptor - in scala - work luciddb, db adaptor supplied default mysql only.

the motion chart in particular thing of great beauty.

update

lucid great way deal masses of data, happily working sizes in excess of 1tb. it's column-oriented (like vertica or sybaseiq), won't incur i/o cost of fetching entire rows of data select couple of columns.

also useful fact lucid queryable via sql , has jdbc client driver, coupled google visualisation java library, ideal match, library able translate of own query format sql, minimizing amount of processing has post-query.

i'm running inside scalate framework, building javascript show charts dynamically. way can change query params based on other controls in page , push new data chart without needing page reload. depending on how heavyweight site be, lift might better fit you.

the whole thing took me week set up, though did have previous experience of working google library.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
