Dear Experts,
I have a requiremnet to generate a specific Line Chart in SAP. User will execute one program which will provide a report. The report will be a simple ALV grid report where User needs a customized Graph button. On clicking the button the program should generate the sample graph provided above. Curently I am working in SAP 4.6C version. I know SAP has already provide few chart and diagram display functionalities which are present in ALV. But above Line Chart is not among those. How to acheive the above objective?

Dear Mathews and Kai,
               Thanks for the help extended by you all regarding the problem faced by me. I didn't adopt the ways as per explained by you, but I studied a lot and procedures to create custom graph as per said by you. I found a unique way to achive my target by manipulating the variable list data and calculating the constant value of Upper/ Lower Threshold level. In this way I used the same old ALV grid technique to obtain the graph. Thanks for your help.
Regards,
Pulokesh

  • Create line chart/graph

    Hi,
    I've created a waveform chart that takes in an integer data point every seven seconds. I'd prefer it if the chart directly connected the data points to form a line chart instead of going down to zero during the seven seconds between readings. I checked around labview briefly but couldnt find any line charts. Is there a setting I can chanhe of a type of chart i should use to get a basic line graph?
    THanks

    The default chart is a 'line chart'. Right click on the plot legend and look at the interpolation. Unless you changed the Fill Base Line option, the chart will not drop to zero unless you are passing it a zero value.

  • Line Chart/Graph for a Matrix report in Oracle Reports 10g

    Hello,
    If you have a Matrix report, say Month Name as rows, Year as columns (for example 2007, 2008, 2009) and sum of Sales dollar value as cells...I want a Line Graph which shows Months on the bottom axis and Years represented by lines and the sales value as the trend or data points on the horizontal line...it seems Oracle Reports cannot do this sincethe Chart wizard does not show either the Months or years as selectable fields for either X or Y axis.
    I can easily write a sql which does the pivot and produce the results for Sales by month for last 3 yrs but in this case I would have to provide column alias similar to say CURRENT_YEAR, PRIOR_YEAR, PRIOR_PRIOR_YEAR. Then, the Chart wizard works correctly but the Legend shows the column alias which is not very desirable for an executive level report.
    I was hoping that since a matrix report shows the correct column names, the legends will pull through correctly but I am stuck since the Chart for a matrix report doesn't work as I described above.
    Does anyone know how to do this type of Chart on a Matrix?
    Thanks,

    The way I'd do it is with a 3D-graph, I think you need that otherwise you will not be able to represent it properly ...
    You will need to create another query just for the graph, which will create another group, containing only 3 columns (YEAR, MONTH, SALES), then start your Graph Wizard, then you will see two groups, select the one containing the 3 columns and when asked for the X-axis categories select both YEAR and MONTH, then for Y-axis select SALES.
    That way it should work...

  • Line Chart / Graph Colors

    How come I can change the colors of a bar graph series but not a line graph series?

    Post Author: desselle
    CA Forum: Charts and Graphs
    Hello,
    I got the problem fixed w/ the line graph not making the data lines the same color on the report as on the frmPlot graph.   Compare the two screen shots below.   The problem was as follows:  When I created the graph (in the Chart Expert) the field u201CReadingDateu201D was not one of the Report Fields, and all the other fields were Report Fields (Reading, LowAlarm, UpperAlarm, LowerLimit, & UpperLimit). See the 3rd screen shot below.  ReadingDate does show up as a Report Field now but it wasnu2019t at first.   Originally, this field was only available in the Chart Expert as a recordset field.  When I changed this field to be a Report Field, the graph then allowed me to change the data series line colors.   This was not obvious at all.   From the beginning when I setup the graph and passed in the recordset from VB it graphed all of the data series fine.   The colors that the Chart Expert chose for each line just didnu2019t match what was on the frmPlot graph.   Anyway, it is working now.     I can at least say I learned (somethingu2019s to-do and somethingu2019s not to-do) a good bit about Crystal Reports in the process.
    Thanks

  • JavaFX Update Line Chart on Tab pane

    Hi all,
    I am wondering can anybody help with this problem.
    I have an application that can create a new tab when the LineChart FXML view is called by way of onMouseClicked event from a bar graph (using scenebuilder). However, I need this Line chart to update when the user clicks a new bar on the bar graph page to show this new data.
    Initially the Line chart tab will open and display data from the first bar graph click and when I click another bar in Tab A (bar chart) if it has the same number of rows it will refresh the LineChart tab otherwise I get an error. Then if I try to load another line graph tab using a different bar graph as the source I get a child duplication error
    (So tab A has a bar graph that calls tab B to represent data as a line graph, however it wont do it more then once when there is a different number of points to show)
    (Also tab C, another Bar chart will not load a new tab) Exceptions below & Class detail below.
    I am using clear() to empty the observable list I have which is used to populate the graph and table before it reads in the new data values
    What is the proper way/ best way to dynamically add another tab and update the chart in the tab with new values? Any help would be appreciated.
    I am getting the following exceptions:

  • Drill Down for Multiple Series in a Line Chart

    Hello,
    I seem to have a problem with the drill-down functionality in a line chart that has multiple series.
    I have a line chart that displays the readings of a patient over a period of 1 month. For each day, there is the glucose level reading, blood pressure reading, etc... So, each reading is a different series in my line chart graph.
    The basic requirement is: With a mouse over event on the chart, I am willing to display all the data that belongs to that day. The data will be displayed at the bottom of the screen in a small panel. It is very simple to do it when the line chart has only 1 series:
    i) Enable drill down.
    ii) Choose 'Row' as insertion type.
    iii) Fill out the destination field.
    iv) Make sure your labels (at the bottom of the screen) get the data from the destination cell.
    When there is more than one series, it becomes very difficult. XCelsius will not let me use the same destination cells for different series. So, I will have to use other destination cells. In that case, I will not know on which day is the user on. Is there any way to achieve this functionality?
    Let me know if you need further information.

    This is certainly possible, but there's a bit of a trick to it (and really hard to explain without screenshots!). There's two halves to it:
    1. Write the date that has been selected to a cell (for each series).
    2. Write the name of the series that was clicked to some cell (this is the property 'Series Name Destination').
    So let's say your three series are Glucose, Blood Pressure and Temp. Have those series names in B1,C1,D1 (with your dates down in column A). Insert a row below the series names (2:2), and then set up your insertion type for the chart as 'row'. The source data (for all three series) should be your list of dates in column a. The insertion cells for the three series will be, in order, B2,C2,D2. Now, depending on which point is clicked in the chart, the selected day will be inserted into one of those three cells. Completely useless unless you know which series was clicked.
    So you need to insert the name of the series that was clicked ('Series Name Destination') into the spreadsheet, let's say in F1. The rest is just Excel formulas. The logic is, you can now tell what series was clicked, and go and look up the date that was inserted for that series, then go and look up the row that corresponds to that date. So to get the date that was just clicked, your formula (in F2) would be =HLOOKUP(F1,B1:D2,2,0).
    Then a VLOOKUP will get the results from that row of data. For example, if I inserted another row at row 3 (to show my 'result' values) the formula in B3 would be =VLOOKUP($F$2,$A$4:$D$13,2,0).
    I hope that makes sense.

  • How to create a Power View bringing barchart and line chart together in same graph

    We are planning to create power view report that has bar and line charts on same graph. Could you please let us know whether it is feasible in Power View & how to add trend line in power view .

  • Combination of bar and line in chart(graph) of Crystal Report XI

    Hi,
    I found the way to combine line and bar in a chart(graph) but I am getting rectangle marker where bar and line are crossed. Our user asked to remove the rectangle marker. Please let me know how to remove the rectangle marker.
    Thanks and Regards,
    Manjunath N. Jogin

    Hi Senthil,
    You are right but I am getting marker rectangle where line and bar coincides.
    I want to remove the marker. 
    User asked following two things:
    1. Marker like star, triangle, rectangle ...not required where coincide line and bar.
    2. Line should be coincided (marker place) at middle of bar.
    Please let me know how to achieve these two things.
    Thanks,

  • Seek 2D Line and Bar Chart Graphs HOWTO

    Can anyone share with me on where I could obtain/teach
    me how to write 2D Line and Bar Chart Graphs ?
    I like the class/program to be called from java code and not
    from command prompt to plot points or bar graphs.
    Please, no vendor recommendations.
    I dont have the $ to purchase.
    Any help is appreciated.
    Thanks

    I checked the web site of JFreeChart and its document
    says to get premium service, it requires $.
    I dont really have the $ to purchase that software.
    It's a vendor product!Just to clarify, JFreeChart is free software, it is licensed under the GNU LGPL. You get the complete source code, including lots of demos, Javadoc HTML pages, an install document in PDF format, and access to the support forum for absolutely no charge. You don't have to pay a fee to unlock special features in the software, everything is there in the free download.
    As a way of funding the project, we sell a JFreeChart Developer Guide which includes a lot more information about using JFreeChart. But it is only the documentation we sell, not the software.
    Hope that helps,

  • 2D Line Chart question

    I have Apex 3.1 . I have created a 2D Line chart with for different series (so there are 4 lines on one chart). I also have a Legend on the left side next to the chart to label whatr each line is for. In my query for those lines I have the Name for the Legend as all CAPS but it shows up as first letter capital and the rest lower case. Is there a way to force it to all upper case?
    The second question I have is that underneath the legend I would like to have some type of text box were I can write a couple lines to help explain what is going on in the graph. Is there a way to do that?

    You basically have only a couple of options here:
    First, turn off the labels and possibly turn them into Hints. They wouldn't show on the chart, but when the user held over the data point, a tool tip would appear showing them the valuable.
    Second, adjust elements of the chart. What you are really looking at here is that your data set is causing this specific issue and not the charting engine or anything like that. You could try to manually change the axis max and min to get more spacing, or you could adjust the height of the chart to get more spacing, but this may not be a viable option. You could have one set of labels above the plotted line and another set of labels below the plotted line that way the values do not overlap with anything. However, from a conceptual standpoint, it will be difficult to determine in code which line should have values above and which should have values below. When your data set changes, you may end up with labels in the wrong place if you hard code where they are at.
    The current XML reference can be found at: http://www.anychart.com/products/anychart/docs/xmlReference/index.html however, that is for anychart 5. I'm looking for the link to the earlier versions...
    You can use this to create custom xml where you can adjust the position of the labels.
    Finally, you do not want expand the height of the chart between two points on the Y axis. That would change the structure of the chart and the visual properties of the chart and the shape of the data would be askew. You cannot do this for good reason. You can though use a logrithmic scale. In most cases though, this is not a practical solution. Data sets need to have very specific characteristics in order to be able to merit a logrithmic scale. Most queries require a simple linear scale.

  • Jfreechart line chart mouse click problem

    i need to implement a line chart where users can click on an area of the chart and highlight it, i have serveral questions regarding how to do this:
    i added a mouselistener to the chartpanel, i can get the points with e.getTrigger().getPoint(), but I need the points associated with the graph point, is that possible?
    i also need to highlight an area of the line chart, I have no idea where to begin, will i be able to change the background of a specific range of points?

  • Legend for a line chart displaying incorrectly

    Hi All,
    I am working with a line chart in webi XI R2. for example conssider the island resort marketing universe. we have 3 resort names like bahamas,US,France and the corresponding "revenue"  for year 1999,2000,2001. Now i want a line chart for each resort and another line for sum of all the revenue.
    So my final line chart contains 4 lines, one each for bahamas,US,France for 1999,2000,2001. and 4 line is sum of all revenues (for all resorts) in 1999,2000,2001.
    I have used a "vertical line mixed" chart for this. All the graph lines are displaying correctly but the legend is displaying wrongly.
    Please advise.

    Hi Raveendra,
    I guess its the 4th line i.e. sum af all revenue that you have added in the same chart is causing the problem.
    My solution is why dont you try and put the sum of all revenue in other chart on the same report.
    May this would help resolve your legend problem.
    If you can give the exact details like what attributes you have selected while running the query and how did you added the sum of all revenue in your chart being more specific, would rather help a bit better in solving the problem.
    Thanks,
    Chirag Desai.

    Hi, 
    I'm trying to create a very simple excel line chart using the report generator toolkit. I have tried both the Excel Easy Graph and Excel Insert Graph vi's (using xlLine type) but cannot get them to output the type of graph im looking for.  
    Using the excel chart wizard im able to generate the type i want, which is the right hand chart in attached an example excel file. The one on the left is the LV output. Any tips on how to get LV to generate the one I want? Seems like a such a simple thing....
    Cheers!!

    Hi David,
    Sounds like you need to configure the graph within LabVIEW. Take a look at the examples available for the toolkit. They should get you going in the right direction. You can get to it by clickin LabVIEW Help>>ExampleFinder>>Toolkits and Modules>> Report Generation Toolkit.
    Some of the formatting VIs for the graph can be found on the following pallette: Programming>>Report Generation>>Excel Specific>>Excel Graphs and pictures.
    Hope that helps.

    Hi,
    Chart Web Parts are useful for visually representing data in line charts, bar charts, and other views. Charts enable you and other users to view performance information at a glance.
    In SharePoint 2013, chart web part is one of the discontinued features. We usually use Excel Service to replace it, however, Excel Service is only available in Enterprise edition, so we need to figure out coding methods or third party tool if you are using
    Foundation edition.
    Here are some links for workaround in your situation, please check if they can be help:
