Hi all,
I 've a question concerning the mapping of x-y in a Matrix. I know allready that If I access a Matrix with OriginC I have to use the MatrixObject and here the SetXY(xmin,ymin,xmax,ymax) function to set a linear mapping.
Actually I would like to assert a special each row a "userdefined" value. These values are possibly stored in a vector. I could also define a nonlinear function to create these values.
Is there any possibility to manage my problem?

Hi,
I am afraid that Origin cannot do that currently. Do you want to make contour graphs? If so, you can put data to worksheet arranged as XYZ (not need linear as matrix does), and then make contour graph from this XYZ data.

Hi Penn,
thx for you reply. I was afraid too. Now it is verified. Don't worry. I'll see how to manage. It is not such a problem. Would have been just a nice additional possibilty for me.
Thx

You can use Tick Indexed Dataset for Tick Labels Type found on the Tick Labels tab of the Axis dialog to display arbitrary values in place of current major ticks.
First establish your Major Ticks. In my example, I will use a Contour graph with X from -5 to 10 incrementing by 5, so my Major Tick Labels are -5, 0, 5, 10 (four values). My Y scale is o 10 100 by 20, so my Major Tick Labels are 0, 20, 40, 60, 80, 100 (six values).
In a Worksheet, fill column A with the 4 values you want to display on the X axis (could be column B - doesn't matter).
Fill column B with the 6 values you want to display.
In your graph, select Format : Axis Tick Labels : X Axis Tick Labels
Set Type to "Tick-indexed dataset"
Set Dataset to the A column of the sheet you used
Change Selection to Left
Set Type to "Tick-indexed dataset"
Set Dataset to the B column of the sheet you used
Click OK
