IBM Mashup Center: V1.1

After going to http://hostname:port/mum/administration and publishing widgetsto the catalog, you may notice a widget named ’null’ instead of the Chart widget.As a workaround, do the following steps:1. In the catalog, go to Home → Upload Widget → iWidget URL and create a newwidget.2. Type the URL of the Chart widget, for example http://hostname:port/mum/chart/Charts.xml3. Update the details of the Chart widget an save it.4. Remove the null widget.Chart widget can display only pure numeric feed dataCurrently, the Chart widget can interpret and display only pure numeric feed datathat does not contain any special characters such as commas, currency symbols,and underscores. For example, the following two pieces of data will not work:100,000 or $100.00. If the feed data does contain non-numeric characters, the chartwill not display the data correctly, and you will get an error message saying thatnumeric data cannot be found.Note: For data in XLS or comma-separated value (CSV) format, note that theheader row and first item in each row can contain non-numeric data, for example:Vegetables,Y2005,Y2006,Y2007,Y2008Potato,19,18,20,57Onion,6,7,6,19Carrot,10,11,12,33Cabbage,9,9,6,24Total,44,45,44,133Chart widget may not display language-specific characters on Y axisWhen configuring the names of the X and Y axes of a chart, if you specify specialfont characters, for example double-byte characters, the characters may not displayproperly on the Y axis.Special characters cause chart data to display incorrectly in Chart widgetAfter configuring the Chart widget with a caption or subcaption that containsspecial characters such as ’&’, ’+’, ’″’, ’’ and ’?’, the caption and subcaptionmay not display properly in the chart, and the chart data may be wrong. As aworkaround, avoid using special characters in the caption and subcaption.Chart widget cannot resolve local URLs properlyWhen using the Chart widget, if you attempt to use a local resource for the data,and that local resource has a URL that begins with http://, users will get an errorwhen trying to access the Lotus Mashups main page using an HTTP protocol. Alocal resource means that it is hosted on the same sever as Lotus Mashups. Forexample, the resource can be a feed that is uploaded to the catalog, and the catalogis installed on the same server as Lotus Mashups. A sample URL may look like thefollowing:http://hostname:port/mashuphub/client/plugin/generate/entryid/12/pluginid/18As a workaround, view the feed details in catalog, right-click the feed URL, andcopy it as a link. This changes the HTTP to HTTPS in the feed URL. For example,the URL above would become the following:20 IBM Mashup Center: V1.1
