    chart-image issues Java

    Attachment: Present (inaccessible)
    We use Aspose Cells 2.5.2 (instead of current version Aspose 2.5.4) because of some issues in 2.5.4

    In both versions I found following issues:
    When I save a chart with #NV values to an Image, the series with the #NV value does not have thousand-seperators and the datalabel has no text. 
    (
    see attachment: barcharts.zip 
    e.g. "tom" 2. bar has no label
    e.g. "spontaneous awareness" has a label "1100" instead of "1.100"
    )

    I also found out, that when I invoke "chartPoint.getDataLabels()" no thousand-seperator is beeing displayed in the image (see attachments: stackedcharts.zip)

    In a stacked bar diagram the legend order in the image is different to the legend order in the excel file
    (
    see attachment: stackedcharts.zip
    "Total" is in the image on first position, in the excel at last position
    )

    In 2.5.4 the thousand-seperator does not care about local number formatting :
    I set the workbook-locale to German and English, but the datalables in both chart-images have the same number formatting (1.000,00)
    This worked in 2.5.2 (see attachment: barcharts.zip)

    Please provide us a solution for that

    Re: chart-image issues

    Hi,

    I have another problem with the image-quality. I tried improve the quality for JPG and PNG with the following methods, but could not recognize any difference

            imgOpts.setFashion(FileFormatType.UNKNOWN);
            imgOpts.setQuality(100);
            imgOpts.setHorizontalResolution(2048);
            imgOpts.setVerticalResolution(1536);

    and
            imgOpts.setFashion(FileFormatType.UNKNOWN);
            imgOpts.setQuality(1);
            imgOpts.setHorizontalResolution(400);
            imgOpts.setVerticalResolution(300);

    (See attachment barchart_quality.zip)

    Hi,

    How long do you think does it take to get a fixed version for all the issues?

    Hi,
     
    We are still working on these issues and will try to provide a fix in this week which may improve the generated image for chart.

    For the quality of generated image, we are afraid we cannot support it soon. Currently the quality options take effect only for converting sheet to images.

    Hi!
    During my tests I found another issue like this.
    I attached a .ppt showing a dark image where parts of it seem missing or merged together at the left side.

    Looking forward to your reply.

    Hi again!
    Another issue occured today: One specific chart is cropped slightly, so part of the text is missing.
    (refer to attachment: right chart, left border - next to the dark brown piece of the cake)

    Can you look at this too?
    Looking forward to your reply.

    Hi,

    We have fixed the issues of chart2image in your original post. For the issue of number format for locale German and English, We have tested 2.5.2 but get the same result with current versions. We think maybe you used different locale settings for your jvm so that you can get the correct number format. Also, with recent versions/fixes, you can change locale for number formatting by calling following methods explicitly:
    Workbook.getWorkbookSettings().setRegion(CountryCode.GERMANY);
    Workbook.getWorkbookSettings().setLocale(...);
    Workbook.getWorkbookSettings().setLanguage(...);
     
    And for your latest two issues shown in ppt, we will look into it soon.

    Download:

    Aspose.Cells for Java v2.5.4.15

    Hi,
    we still have the issue with poor results from the Chart.toImage() functionality. Currently we are using Aspose Cells version 7.0.3 for JDK1.5.

    I have found lots of threads regarding the same issues. We tried to use EMF vector graphics with custom resolution but this produces the same poor quality as regular image types like JPEG for example.

    Hi,

    Thanks for your feedback. I have reopened your issue. We will further look into it and update you asap.

    Please also create a sample application to replicate the problem using the latest version: Aspose.Cells for Java v7.0.3.3 and post here. It will help us in investigation.
