Hi Celine- I'm travelling and don't have time to do this justice, but here's my take on it. I have not been able to follow your code in detail, but here's my take on it. You have some X or Y values. You can use X or Y for those real types. For the Log values, you can create a RealType (e.g. LogX, LogY) which is used for the reference realtype of the LogCoordinateSystem. VisAD automatically does the calculations converting the values to the log values. What you have below looks like you are trying to go the other way. Your Integer1DSet has index as the reference of the CS so values of 0,1,2,3 will get converted to the log of those values when index is mapped to a scale. I would think you would want it the other way. Another question is are you removing the non-log scalar maps when you switch to log displays and vice-versa? Again, I'm travelling so may not answer until I get back. Don Celine Gestas wrote:
Thank you for your answer but there is no change : points are displayed but not in the log scale, it keeps the default scale. What I changed is : index = RealType.getRealType("index", CommonUnit.promiscuous); indexLog = RealType.getRealType("indexLog", CommonUnit.promiscuous); // new RealType referenceIndex = new RealTupleType(index); LogCoordinateSystem logCSindex = new LogCoordinateSystem(referenceIndex, base); rangeIndex = new RealTupleType(indexLog, logCSindex, null); // use the new RealType index_set = new Integer1DSet(rangeIndex, x_vals[0].length, logCSindex, null, null); 2007/3/26, Bill Hibbard <hiding@xxxxxxxxx>:Hi Celine, If someone has an idea ... RealTupleType rangeIndex = null; // create the index if (log.equals("logX") || log.equals("logY") ||log.equals("loglog")) {index = RealType.getRealType("index", CommonUnit.promiscuous);RealTupleType referenceIndex = new RealTupleType(index); LogCoordinateSystem logCSindex = new LogCoordinateSystem(referenceIndex, base); rangeIndex = new RealTupleType(index, logCSindex, null); index_set = new Integer1DSet(rangeIndex, x_vals[0].length, logCSindex, null, null); } I think the problem is that the RealTupleTypes referenceIndex and rangeIndex are both defined as (index), that is they are both a RealTupleType of the same single RealType. This may also explain the very mysterious Exception you reported in your other recentmessage to the list. Try using different RealTypes in the constructors forreferenceIndex and rangeIndex. Good luck, Bill -- <http://a8-asy.a8ww.net/a8-ads/adftrclick?redirectid=en-mail_a_01>
