Origin Ver. and Service Release (Select Help-->About Origin): Origin 2015 sr2
Operating System: Windows 7 and 10
I am trying to use the code builder to import data and graph on a log-linear graph. However, I cannot find how to programmatically change the y-axis (log) tick label display type. By default it is decimal, which gives y-axis values of 100, 1000, 10000, 100000, 1000000, 1E7, however I would like to switch it to scientific to get nicer labels. Thank you. |

A simple solution (may not be the best practice, as it plugs in a labtalk script):
LT_execute("layer.y.labelSubtype=2");
where the 2 is for scientific, which can be replaced with 1 for decimal, 3 for engineering (1K), and 4 for decimal (1,000). |

Hi,
The OC code to realize it is as following:
void OriginObject_SetFormat_Ex1()
{
GraphLayer gl = Project.ActiveLayer();
// Get all objects' all properties of GraphLayer into Tree
Tree trFormat;
trFormat = gl.GetFormat(FPB_ALL , FOB_ALL, TRUE, TRUE);
out_tree(trFormat); // output format tree
trFormat.Root.Axes.Y.Scale.Type.nVal = 1; // Set Y Axis Type to be Log10
trFormat.Root.Axes.Y.Scale.Rescale.nVal = 2; // Set Rescale to be Auto
trFormat.Root.Axes.Y.Labels.LeftLabels.NumericFormat.nVal = 1; // Scientific Notation
// Apply all format
int nErr = gl.UpdateThemeIDs( trFormat.Root ) ;
if(0 != nErr)
out_str("Fail to Update Theme IDs, theme tree has wrong structure");
gl.ApplyFormat( trFormat, true, true, true );
}
Give it a try and see how it goes!
Regards!

Worked well, I have another question though. I am trying to use OC code to get rid of the legend, looking at the output of the tree, it looks like just adding the line
trFormat.Root.Legend.Show.nVal = 0;
should get rid of the legend. However when I add this line (to otherwise working code) I get a number of compiling errors:
:Error, General Error ( ) contact TD.
:Error, Variable "tr.Root.Legend.Show.nVal" not declared
:Error, general compile error
:Error, general compile error
:Error, error(s) found in compiling function ImportWAXRD

Show is a treenode attribute. Have a try of the following:
trFormat.Root.Legend.GetNode("Show").nVal = 0;
