  • Flex Chart : Customize Horizontal Axis According to Range

    - by maoanz
    I want to build a LineChart with many data. The horizontal axis correspond to the date, but I am not able to find out how to customize the horizontal axis label. With this code, the chart display all the date on the axis and it's not readable. How can we customize the label so it displays only several points on the axis gradually according to the range? Thanks for replying.

  • Chart for deciphering terms in different programming languages

    - by Nathan Adams
    This has been bugging me every since I started to use Python - in PHP you have this ability to use a string as a key in an array. PHP calls these associative arrays. Python calls these dictionaries. Does anyone know of a premade chart that will let me see what the different terminology is in different languages. For example: PHP             | Python Assosicative array | Dictionary

  • Real-time Java graph / chart library?

    - by Joonas Pulakka
    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 acquisition system and plotting it as it comes (time on x-axis, voltage on y-axis).

  • XY-Scatter Chart In SSRS Won't Display Points

    - by Dalin Seivewright
    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 'December 12 2008' and the BackupTime would be '12:53PM.' I have added an XY-scatter chart to the report. I've added a 'series' value for the BackupType (so one can distinguish between a Full/Incr/Log backup). I've added a category value of BackupDate and set the Scale for the X-axis from the Min of BackupDate to the Max of BackupDate. I've then added an item to the Values with the Y variable set to BackupTime and the X variable set to BackupDate. The interval for the Y-axis is 12:00AM to 11:59PM and the formatting for the labels is 'hh:mmtt'. The BackupTime matches the format of the Y-axis. The BackupDate matches the format of the X-axis. 10 entries are retrieved by my Dataset and the Legend is properly populated by the BackupType field. No points are being plotted on the graph and no markers/pointers are shown if they are enabled. There should be a point on the graph for every point in time of each day there is a backup of a specific type. Am I missing something? Does anyone know of a good tutorial dealing specifically with XY-scatter graphs and using them in a way I intend? I am using the 2005 version of SSRS rather than the 2008 version. Screenshot of what my chart currently looks like: In case it could be dataset related: SELECT TOP (10) backup_type, LTRIM(RTRIM(LEFT(backup_finish_date, 12))) AS BackupDate, LTRIM(RTRIM(RIGHT(backup_finish_date, 8))) AS BackupTime FROM DBARepository.Backup_History As requested, here are the results of this query. There is a Where clause to constrain the results to a specific database of a specific server that was not included in the above SQL Query. Log Dec 26 2008 12:00PM Log Dec 27 2008 4:00AM Log Dec 27 2008 8:00AM Log Dec 27 2008 12:00PM Log Dec 27 2008 4:00PM Log Dec 27 2008 8:00PM Database Dec 27 2008 10:01PM Log Dec 28 2008 12:00AM Log Dec 28 2008 4:00AM Log Dec 28 2008 8:00AM

  • Displaying data points in Flex Line chart...

    - by dmose
    I have a flex line chart. Instead of the default behavior of having to hover over parts of the line to see the data points, is there a way to change the rendering of each point and have them always displayed? (almost like a connect the dots type view).

  • Why is Google Charts not showing the right data for me? Are the axis messed up?

Just those data points. Nothing more, nothing less!

  • How to display escaped characters in tmux status bar

    - by walrus
    i am running tmux from a tty on an embedded linux device. (NOT a terminal emulator) because the screen is rather small, i want to add some "icons" to the tmux status bar. to achieve this, i have simply created a font with the appropriate glyphs for things like battery, or wifi. i can load the font, and display the characters with calls that use an escape to the line drawing characters like so: echo -e "\xe\234\xf" \xe escapes me into line drawing character mode, \234 is my created character, and \xf returns me to normal character mode so my terminal doesnt start getting goofy. this works perfectly if i enter the command at the terminal whether tmux is started or not. the issue arises if i then try to use it in my ~/.tmux.conf file for the status bar. i currently have a line like this: set -g status-right "#(echo -e "\xe\234\xf") #(/script/to/output/powerlevel) this simply outputs \xe\234\xf powerlevel this goes the same if i try printf over echo. this is the output i would expect to get on the terminal if i made the call without passing -e to echo, or without enclosing the statement with quotes. i then decided to wrap the calls to the echo or printf in a shell script. again, the script works when called from the terminal, but not in tmux's status bar. now i get the unprintable character "?" instead of my icon, like this: ? powerlevel this is what i would expect if i did not use the line drawing escapes previously mentioned above, or if i tried to copy and paste the character as text using tmux. in addition, the calling of these character scripts screws up the rest of my status-right, as the clock has about 6 digits for minutes when it is called (though it correctly only updates two of them). how can i make tmux respect the escape characters? any help or insight is greatly appreciated.

  • I want to input JSONObject from jquery.post() to a a simple JS chart(bar chart)?

    - by ann-stack
    HI I am very new to both json and js charts. In the example of bar chart, they are giving a hard coded array like this, var myData = new Array(['U.S.A.', 69.5], ['Canada', 2.8], ['Japan & SE.Asia', 5.6] ); var myChart = new JSChart('graph', 'bar'); myChart.setDataArray(myData); Instead of that I want to use the response of $.post() method which is in json. Here is the piece of code. var myData=[]; $.post("JSONServlet", function(data) { $.each(data.Userdetails, function(i, data) { myData[i] = []; myData[i]['text'] = data['firstname']; myData[i]['id'] = data['ssn']; alert("first name " +myData[i]['text']+ " salary " +myData[i]['id']); // I am getting correct data here, but how to assign this myData to barchart }); }, "json"); is this the logic to use or how else can i get username and salary from the response and pass it to the barchart. Please help. I am stuck with this. thanks in advance.

  • Recommendation for high performance WPF Chart

    - by Ajaxx
    We're working on a WPF-based desktop application that charts financial markets information (candlestick charts, overlayed indicator curves, volume, etc). The charts are displayed in real-time with responses to market ticks being shown in real-time (updating one to two times per second is probably a reasonable display refresh policy). We've been looking for a software package (commercial is fine by us) that has the capability of displaying these charts. Additionally, we'd like to have an approach that can render the initial amount of data in a reasonable timeframe (give or take 100-200ms from the time we hand the data over to a complete render on screen). Also we view multiple charts (5-10) simultaneously so a solution that chews up 50% of my CPU to display one chart really isn't going to work well. Has anyone had any good experiences with charting controls. We've had to hand roll the last few charts we've done and I'd prefer not to do it again. Solutions that can make use of the GPU to minimize CPU utilization would be nice as well.

  • Dyanamic Chart Series Labels

    - by McVey
    I have some Visual Basic Code that creates a chart for each row. It sets the series values using this code: .SeriesCollection(1).Values = "=" & Ws.Name & "!R" & CurrRow & "C3:R" & CurrRow & "C8" What I am struggling with is how do I set the series labels? The series labels will always be the 1st row and be in the corresponding column. I know this is much simplier than the code above, but I am stumped. Any help is appreciated.

  • Element 'Chart' is not a known element - dotnetCHARTING

    - by Ryan
    Hi, I am using dotnetCHARTING: the dll is installed in the GAC and referenced in my web.config (all versions appear to match). The project has a reference to the dll. web.config: <add assembly="dotnetCHARTING, Version=5.3.3540.17054, Culture=neutral, PublicKeyToken=af2cd47db69d93bd"/> The site code compiles ok, but all aspx pages using the charting library complain that the Chart tag does not exist (warning that it might be a compile error). The aspx pages do not render the charts. Each page has a reference to the assembly: <%@ Register Assembly="dotnetCHARTING" Namespace="dotnetCHARTING" TagPrefix="dotnetCHARTING" %> Does anybody know what could be causing this? Thanks a lot for any help - I'm quite desperate to get this resolved. Ryan

  • How t have the RDLC pie chart show ranges instead of individual values

    - by Emad
    I have some data coming from a custom dataset that look like the following example Person Age P1 20 P2 21 P3 30 P4 31 P5 40 And I want to develop a pie showing the age distribution against the age. The point is that I want this Age to be shown in ranges. (20-29, 30-39, etc for example So we have: Slice with total number =2 (P1 + P2) as age is 20-29 (one at 20 and another at 21) Slice with total number =3 (P3 + P4) as age is 30-39 (one at 30 and another at 31) Slice with total number =1 (P5) as age is 40 (one at 40). How can i customize the pie chart to aggregate values by ranges that I can define?
