rikseventyseven	Posted - 06/20/2009 : 1:13:45 PM Origin 8.0 I'm pretty new to OriginC programming. I have the following problem: I manipulated and did some math using some worksheet columns. Now, I wrote a small code that generates a plot using these datasets. I can set the line colors and marker size/type. Now since I'm fanatic of Top and Right axes I would like to activate them. I read an example where they use the tree structure to import the properties of the axes. I can set for example the position and the color of the Bottom and Left axes using : trAxes.X.Ticks.BottomTicks.Major.nVal = 1; // Set the major ticks to In & Out format for X axes //trAxes.X.Ticks.TopTicks.Show.nVal = true; trAxes.Y.Ticks.LeftTicks.Major.nVal = 1; // Set the major ticks to In & Out format for Y axes //trAxes.Y.Ticks.RightTicks.Show.nVal = true; trAxes.All.Ticks.All.Color.nVal = 0; // Set the color of axes to bule gl.ApplyFormat(tr1); The frustrating thing is that if I uncomment the green lines I cannot compile and I get an error! Why?!!?!? I tryied to use the tree_to_str function on the layer's tree and these parameters for Top and Right axes are there! What's wrong with this code?! Thanks a lot! rikseventyseven ------------------------------- "Stay hungry, stay foolish."

rikseventyseven	Posted - 06/22/2009 : 10:27:10 AM That solved the problem!!! Thank you very much for the hint! In 30 sec you managed to do better then me in 2 hours... Thank a lot! ------------------------------- "Stay hungry, stay foolish."
cpyang	Posted - 06/20/2009 : 8:35:12 PM The problem is with the Show property. Origin C TreeNode has a built-in property called Show and thus a tree tagName called Show will lead to a conflict. We can fix this in later SR but for now, you can use lower case "show", since the theme tree tagname is case insensitive. The following code will work fine: void show_top_right_axes() { GraphLayer gl = Project.ActiveLayer(); if( !gl ) return; Tree trFormat; // first turn on top-right axes with a separate set theme call trFormat.Root.Axes.X.Ticks.TopTicks.show.nVal = 1; trFormat.Root.Axes.Y.Ticks.RightTicks.show.nVal = 1; int nErr = gl.UpdateThemeIDs( trFormat.Root ) ;//assign node IDs to all nodes in trFormat, return number of errors if(0 != nErr) out_str("Fail to Update Theme IDs, theme tree has wrong structure"); gl.ApplyFormat( trFormat, true, true, true ); //update graphlayer's format // then change settings can be done after needed axes are already turned on trFormat.Root.Axes.X.Ticks.BottomTicks.Major.nVal = 1; // Set the major ticks to In & Out format for X axes trFormat.Root.Axes.Y.Ticks.LeftTicks.Major.nVal = 1; // Set the major ticks to In & Out format for Y axes trFormat.Root.Axes.All.Ticks.All.Color.nVal = SYSCOLOR_BLUE; // Set the color of axes to bule nErr = gl.UpdateThemeIDs( trFormat.Root ) ;//assign node IDs to all nodes in trFormat, return number of errors if(0 != nErr) out_str("Fail to Update Theme IDs, theme tree has wrong structure"); gl.ApplyFormat( trFormat, true, true, true ); } Thanks for posting about this problem, and I have updated our ocwiki with a new example: http://ocwiki.originlab.com/index.php?title=OriginC:Accessing_Graph_Format_with_Theme_Tree#Turn_On_Top-Right_Axes
