There was an earlier thread on Java graph or chart library, where JFreeChart was found to be quite good, but, as stated in its FAQ, it's not meant for real-time rendering. Can anyone recommend a comparable library that supports real-time rendering? Just some basic xy-rendering - for instance, getting a voltage signal from data acquisiti...
Ideally I'd like to do as little preparation data work on the server as possible. The less I have to do to prep the data from the database to make a given chart, the happier I am and the more view I can make in the time. Some of the things I'd like to chart are, for example: The distribution of a series of response times The number of...
Hi everyone! Is there an easy way to draw a date/value chart in Python, if the "dates" axis had non-equidistant values? For example, given these: 2009-02-01: 10 2009-02-02: 13 2009-02-07: 25 2009-03-01: 80 I'd like the chart to show that between the 2nd and 3nd value there's a longer gap than between the 1st and the 2nd. I tried a fe...

I'm using the asp.net charting control, and liking it for the most part. However, I would like my charts to size with the panels they are contained in. I cannot set the width of the chart to 100%, I have to give them an exact size. I don't want to stretch and distort the rendered chart image. Does anyone have an example of how I might...

I am attempting to create a stacked chart using the relatively new Microsoft Chart Controls. I am sure that I am missing something obvious but a bit of help will go a long way. The below code creates a chart with two columns. I'd like the columns to be stacked on top of each other. Further, I'd like the total of the two to be displayed...

I'm trying to add a Label to the LegendItem objects in my chart's legend, without much success. I extended the LegendItem class, and the constructor of the class I made is below. The problem is that the Label you see me trying to add doesn't appear in the legend item. It's there (I can find it with getChildByName), but it's invisible, fo...
I have some charts I've copied over from an identical workbook, but the source data for each chart (42 charts, with 6 series in each) still contains the full filename path. The source sheet and cells are identical, so I just want to find the path string and replace it with "". However, I can't find a way to get the name of the sourcedata...
I need to show a Line Chart on an ASP.NET page where each data point has a tooltip that shows its exact X and Y values. A chart for a particular dataset will probably only ever be requested once, so caching is disabled and the chart will be regenerated if it ever needs to be shown again. Restrictions: Needs to work in a web garden en...

I need to make a chart with an optimized y axis maximum value. The current method I have of making charts simply uses the maximum value of all the graphs, then divides it by ten, and uses that as grid lines. I didn't write it. Update Note: These graphs have been changed. As soon as I fixed the code, my dynamic graphs started working, ...
I have a need to output a graph in reporting services 2005 with 2 Y axises. It does not appear that this is possible in RS2005 and I have no idea what options may be available to me. It sounds like RS2008 may solve this issue, but I do not believe that is in the cards for me. What other options might I have? ...
I am looking to to use an SSRS line chart to graph ending run times of jobs. I am using runtim on the y-axis and date on the x-axis. The graph looks like a flat line and the times do not show up on the y-axis, but integers show. I also want to put a target line at a specific time to show our SLA time. Here is example of data I am try...
I want to create a graph representing the frequency of updates to a site (for example, how often I have posted to my blog over the past 5 years). One obvious way to do this is to plot "number of entries posted per month" for the past 60 months, but this feels unsatisfying. Should I be looking at using something like a rolling average ins...
