I'm writing some data acquisition software and need a gui plotting library that is fast enough to do realtime updated graphs. I've been using Nplot which is pretty good for a free library, but I'm wondering if there are any better libraries (preferably free or cheap)....
Has anyone had good experiences with any Java libraries for Graph algorithms. I've tried JGraph and found it ok, and there are a lot of different ones in google. Are there any that people are actually using successfully in production code or would recommend? To clarify, I'm not looking for a library that produces graphs/charts, I'm look...
I have implemented this Graph: ListenableDirectedWeightedGraph g = new ListenableDirectedWeightedGraph( MyWeightedEdge.class); in order to show what the class name says, a simple listenable directed weighted graph. I want to change the label of the edges and instead of the format return "(" + source + " : " + target + ")"; I wa...
I have the need to do some graphing (bar, chart, pie, trend) and instead of using Infragistics or manually drawing the graphs I want to use Silverlight. My current ASP.NET application was upgraded to 3.5 and I have added a Silverlight Application project. Consuming the output inside of the existing master.page layout or inside of user ...
I am trying to tweak an existing LineChart (WebUI.UltraWebChart) by adding goal-line. This seems nearly impossible to draw a simple "MAX GOAL" line (either horizontally or vertically). We will eventually either upgrade to the newest bits or revamp into Silverlight graphs, however, this needs resolved now. ...
Hello, I am working on a graph in WPF, in each section there are thousands of points to draw. The performance for rendering this graph is horrible. Does anyone have any experience with a filter that will represent the graph with much fewer points - similar to the way a stock graph draws itself when its zoomed out. Thank you. ...
Hello, I have a large-ish Oracle table containing rows representing units of work, with columns for start time and end time in addition to other meta-data. I need to generate usage graphs from this data, given some arbitrary filtering criteria and a reporting time period. E.g., show me a graph of all of Alice's jobs for the 24-hour pe...
I'm a bit confused with this one. I have a Dataset with a BackupDate and a BackupTime as well as a BackupType. The BackupDate is comprised of 12 characters from the left of a datetime string within a table. The BackupTime is comprised of 8 characters from the right of that same datetime string. So for example: BackupDate would be 'D...
As per the title. I am trying to create a simple scater plot, but haven't found any Python 3.0 libraries that can do it. Note, this isn't for a website, so the web ones are a bit useless. ...
Can anyone recommend a free grid/graphing component for C#/.NET? I'm having a look at NPlot right now, but so far I'm finding it quite troublesome. EDIT: I particularly need something that plugs into Windows Forms - I'm not doing ASP.NET, and don't really fancy reproducing my graph using Google's API every time I get a new data point (...
I am currently working on a Flot graph, the API which seems pretty powerful overall, although examples of advanced use are not widely documented. The API suggests there are ways to set hoverable on the graph, not that I am sure what exactly that means I can do with it. I would like to know if anyone could contribute some examples tha...
I have a basic bar chart I'm presenting in flot (5 bars, displaying the % per status). $.plot($("#placeholder"), [ { label: 'Failed', data: [[0,10]], bars: { show: true } }, { label: 'Passed', data: [[1,15]], bars: { show: true } }, { label: 'Not Run', data: [[2,30]], bars: { show: true } }, { label: 'Blocked'...
I'm doing some research on online Graphing packages for different languages and would like to know what current up-to-date graphing packages there are for Perl which are worth investigating Minimum desired capabilities should include the kind which Google offers through its API A brief synopsis of the key benefits of the recommended pa...
Are there any open-source charting libraries (at this point, I don't care what language/platform it's available for) that can produce "really, really, ridiculously good looking" plots, preferably with features for "scientific" plotting such as error bars? Keynote and Office 2007 really opened my eyes to the aesthetics, and I'm accustome...
I have some python code that receives a message every so often containing a timestamp and an edge transition, either low-to-high, or high-to-low. I'd like to graph each transition on a stripchart for a quick and dirty visualization of the digital waveform with the minimal amount of effort. Can you recommend any methods or packages that ...
Let's say I have a sine curve in ZedGraph that goes from -10 to +10 on the y-axis. I'd like to be able to put limits on the curve (let's say minimum of -5, and maximum of +7), such that anything below -5 and anything above +7 is shaded, and everything in the middle is not. Is this possible in ZedGraph? Is this possible in any OpenSource ...
I'm new to Rails (and StackOverflow), so I apologize if this is a "dumb" question. I've put together a really simple Rails application. It receives data from another server (via HTTP POSTs). I would like to graph the data sent - in particular, I am looking to graph temperature versus time. I am trying to use Flotilla to generate these g...
I'm about to start working on a PHP application that allows a user to track their progress on a day to day basis. I'm looking for a good graphing library, preferably PHP and or Javascript (JQuery would be good) which will allow me to name each bar on a bar graph with a date (10 Feb, 11 Feb, 12 Feb, etc.) probably on it's side or at a 45...
I'm trying to produce a timeline for my real-time embedded code. I need to show all the interrupts, what triggers them, when they are serviced, how long they execute, etc. I have done the profiling and have the raw data, now I need a way to show the timeline graphically, to scale. I've been searching for a good tool, but haven't come ...
Report design, generation and maintenance isn't hard, but it is dull. We have a number of legacy (to quite different degrees of legacy) reports in Crystal Reports XI. These are designed for A4/PDF - not necessarily printed, but to be of a predictable layout and there's no possibility of us retiring them any time soon. All connect to ex...
