Please help me stop BI publisher from staggering the labels under the x-axis. i cannot find the label rotation property in the web gui.
i found https://blogs.oracle.com/xmlpublisher/more-charting-tips discussing inserting a tag in the xml however, I am a complete novice when it comes to soap request. I am not sure how to insert the xml into my request.
<O1TickLabel textRotation="TR_HORIZ_ROTATE_90" automaticRotation="AR_NO_ROTATE"/>
Here is my xml for the request from server command line (
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v2="http://xmlns.oracle.com/oxp/service/v2"> <soapenv:Header/> <soapenv:Body> <v2:runReport> <v2:reportRequest> <v2:attributeFormat>pdf</v2:attributeFormat> <v2:reportAbsolutePath>${REPORT_PATH}</v2:reportAbsolutePath> <v2:reportOutputPath>${REPORT_NAME}</v2:reportOutputPath> </v2:reportRequest> <v2:userID>${USER}</v2:userID> <v2:password>${PASSWORD}</v2:password> </v2:runReport> </soapenv:Body> </soapenv:Envelope>
