Origin Ver. and Service Release (Select Help-->About Origin): 8.5.1 SR2
Operating System: Win7
Hello,
I'm currently wrapping up my MSc thesis report, which has a ton of Origin graphs. As I knew very little about Origin when I started, I'm stuck with a whole bunch of mismatched graphs.
I'm looking for a flexible way to change properties of all instances of a certain type of element in a graph, notably:
* symbol size
* plot line width
So I'd like to be able to run some code that says e.g. "change the size of every symbol in this graph (on multiple layers) to 7"
I tried copying format, but that doesn't work, since that also changes the symbol itself. The same would happen with themes I believe. So I'm turning to scripting now, hoping to find a workable solution that doesn't involve me clicking graphs for the next two days.
If anyone could point me in the right direction with perhaps some sample code... I have basic programming experience, but I don't know how to reference things like graphs, layers, plots, symbols etc. in Origin C. Many thanks in advance for any help given!
Edit: After playing around with some examples I've made some headway. I can change all the symbol sizes in one layer using:
void ss(int symsize)
{
GraphLayer gl = Project.ActiveLayer();
if(gl)
{
foreach(DataPlot dp in gl.DataPlots){
if(dp)
{
Tree trFormat;
trFormat = dp.GetFormat(FPB_STYLE);
trFormat.Root.Page.Layers.All.Curves.All.Symbol.Size.nVal = symsize; //set the size of symbol
if(dp.ApplyFormat(trFormat))
{
out_str("success");
gl.GetPage().Refresh();
}
}
}
}
}
However, when I tried to adapt this to looping through all the layers in a page, it doesn't do anything. This is the code I used:
void ss(string grname,int symsize)
{
GraphPage gp(grname);
foreach(GraphLayer gl in gp.Layers)
{
if(gl)
{
foreach(DataPlot dp in gl.DataPlots)
{
if(dp)
{
Tree trFormat;
trFormat = dp.GetFormat(FPB_STYLE);
trFormat.Root.Page.Layers.All.Curves.All.Symbol.Size.nVal = symsize; //set the size of symbol
if(dp.ApplyFormat(trFormat))
{
out_str("success");
gl.GetPage().Refresh();
}
}
}
}
}
}
This takes the graph name as an argument. Ideally, this would work for the currently selected graph. |

Thanks again Castiel!
I'd already gotten the line width working, after I replaced FPB_STYLE_SIZE with FPB_ALL. Talk about trying and trying again... :D
Thanks for the axis width code. It makes very little sense to me that this would be referenced through the ticks node, but there you go.
I got a nice routine written now, and converting all my graphs to my specific setup works like a charm. Thanks again!

Neither can I find such reference. Have to try again and again. That properties not defined do not show up, I think it's reasonable.
void ss(string grname,int symsize, double linesize, double yrsize)
{
GraphPage gp(grname);
foreach(GraphLayer gl in gp.Layers)
{
if(gl)
{
Tree trFormat;
trFormat = gl.GetFormat(FPB_STYLE_SIZE|FPB_STYLE_LINE, FOB_ALL, TRUE, TRUE);
foreach( TreeNode tnGroups in trFormat.Root.Groups.Children)
{
tnGroups.Symbol.Size.nVal = symsize;
tnGroups.Line.Width.dVal = linesize; // there must be a 'LINE', or nothing happens
}
foreach( TreeNode tnCurves in trFormat.Root.Curves.Children)
{
tnCurves.Symbol.Size.nVal = symsize;
tnCurves.Line.Width.dVal = linesize;
}
trFormat.Root.Axes.Y.Ticks.RightTicks.Width.dVal = yrsize; // there must be a 'RIGHT AXIS', or nothing happens
gl.ApplyFormat(trFormat, TRUE, TRUE);
}
}
}

Thanks Castiel! That seems to work and faster than what I had.
I see that you're defining a node at some point in the tree and referencing from there. That makes sense.
Do I understand correctly that you define two nodes to change symbols in both individual curves and grouped ones (where you can have e.g. incremental symbol shapes)?
I managed to change the tick size for all axes using:
void ss(int symsize, int ticksize)
{
GraphPage gp=Project.Pages(-1);
foreach(GraphLayer gl in gp.Layers)
{
if(gl)
{
Tree trFormat;
trFormat = gl.GetFormat(FPB_STYLE_SIZE, FOB_ALL, TRUE, TRUE);
foreach(TreeNode tnGroups in trFormat.Root.Groups.Children)
tnGroups.Symbol.Size.nVal = symsize;
foreach(TreeNode tnCurves in trFormat.Root.Curves.Children)
tnCurves.Symbol.Size.nVal = symsize;
foreach(TreeNode tnAxes in trFormat.Root.Axes.Children)
foreach(TreeNode tnTicks in tnAxes.Ticks.Children)
tnTicks.Length.dVal=ticksize;
gl.ApplyFormat(trFormat, TRUE, TRUE);
out_tree(trFormat);
}
}
}
This works fine, so I think I have this tree node thing down.
One more question: is there a full tree reference somewhere? I couldn't find it. I've explored the tree of my current graphs using out_tree(trFormat), but properties that aren't defined in my graph don't show up in the output.
Edit: and another: how to access the line width? tnCurves.Line.Width.dVal=linesize doesn't seem to work (in a combined Line + Symbol plot).
Edit: and another: I can't figure out how to reference the axis line width. If I look in the theme explorer, it's in 'Global', under 'root', but it would seem to me that if I set this, other things would also change. Any way to get more fine grained control over the axis line width (and e.g. color; I'd like to be able to change the color of e.g. only the right axis and not the other 3)?
Thanks again for helping! |
