Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

      Re: Chart help

      Hi Stan

      Thank you for your help but I should have been more descriptive in my question.

      I'm using a dialog with a chart that I copied from the Learning Xdialog examples and the code is as follows:

      dim objSettings as Reporting::ReportChart
      objSettings.chartType = "Bar Vertical Grouped"
      objSettings.sourceType = "Table"
      objSettings.sourceTable = "Sales Orders"
      objSettings.DataExpression = "box"
      objSettings.CategoryExpression = "ass_date"
      objSettings.DataLabelExpression = "dtoc(ass_date,'9-') + ' '"
      objSettings.Summarization = "total"
      'objSettings.titleExpression = "'Assembly Schedule'"
      objSettings.width = 800
      objSettings.height = 500
      objSettings.styleSheet = <<%str%
      chart-title {
      font: Tahoma,15pt;
      objSettings.filterExpression = "has_ship='n'.and.stage='sold'"

      dim url as c = objSettings.GenerateURL()

      ' Build a bitmap image from the chart defintion
      dim ac as Charting::Chart
      dim binImg as b = ac.SaveImageToBmp()

      ' Load bitmap into memory

      ' Display the bitmap

      ' Remove the bitmap

      I'm sure I've missed something but I'm at a loss as to what it is.

        I think you need to add

        objSettings.DataFormat = "alltrim(str( convert_type(<value>,\"N\") ,12,1,\","))"
        objSettings.DataLabelPlacement = "Chart"

        to label the columns on the graph.

        Will probably mess up something else.

        You can discover some of the other properties of the objSettings object while editing your code by typing


        and observing what the autocomplete makes available.

          Hi Stan

          Thanks for your help, I've been messing with the objSettings properties for a while.

          Is there a place where there is a description of the properties?

          I'm trying to get a pretty simple chart with the dates on the x axis, the values on the columns. I would have thought this would have been a pretty easy thing to do but for the life of me I can't seem to get it to work

          Should I do a summary operation of the table first then pull data from the results table? I would have thought that step would be unnecessary for such a simple chart.

            I may be getting somewhere. The screenshot below is the result of this code. Seems similar to what you are attempting

            dim chartStyle as c = "Bar Vertical Grouped"
            ' Initialize the chart definition - how table data maps into chart
            dim objSettings as reporting::reportChart
            objSettings.ChartType = chartStyle
            objSettings.sourceType = "Table"
            objSettings.sourceTable = "invoice_items"
            objSettings.CategoryLabelExpression = "Product_id"
            objSettings.DataExpression = "Extension"
            'objSettings.DataLabelExpression = "Product_Id-"+crlf()+"' ($'+Extension+')'"
            [COLOR="#FF0000"]objSettings.DataLabelExpression = ""[/COLOR]
            objSettings.DataFormat = "alltrim(str( convert_type(<value>,\"N\") ,12,2,\"$(B\"))"
            objSettings.DataLabelPlacement = "Chart"
            objSettings.eachGroup = "Detail"
            objSettings.seriesType = "Single"
            objSettings.Summarization = "Value"
            objSettings.width = 800
            objSettings.height = 500
            objSettings.styleSheet = <<%str%

              Hi Stan

              Not really sure what happened but after I had abandoned it for a few weeks to work on another project, when I came back to it, the chart works just like I wanted it to. Damn if I know what I did

              Thanks for your help
