Origin Version (Select Help-->About Origin): 7.5 SR5
Operating System:Win 2000 Pro
I can activate a graphpage using LT_execute("window -a Name");, but the page is not maximised. How can I achieve this using OC?
Additionally, is there a way to add a second x-axis on top of the graph page (For each x-value I have a y-value and a second x-value. I want the second x-values as a secondary x-axis)

Hi Ralph,
Ok, now I understand (I think!) as to what you want...
To do this you need two layers - not possible with just one layer.
I think then the easiest way to do this is as follows:
1> Go to the Origin GUI, start a new graph (which will have one layer)
2> Right-click near the layer icon on top left, and select New Layer->Top X
3> Customize other things that you may want to do (other than scale settings) and save this as a template.
Then, in your OC code, create an instance of the template saved above, and then use code such as this to set the scale of the 2nd layer X axis to arbitrary values:
// Create the graph using the custom template
GraphPage gpg = Project.Pages();
GraphLayer gly0, gly1;
// Point to the first layer and move in data etc as you need to
gly0 = gpg.Layers(0);
//...
//...
// Now point to second layer
gly1 = gpg.Layers(1);
//
// Can get format into tree and dump to see what is available
Tree tr;
tr = gly1.XAxis.Scale;
out_tree(tr);
//
// Set the from, to and increment value as desired
gly1.XAxis.Scale.From.dVal = -100;
gly1.XAxis.Scale.To.dVal = 45;
gly1.XAxis.Scale.Value.dVal = 25;
I am suggesting again to begin with a custom template because that wil l make things easier - otherwise you will need to programmatically add a second layer, position it correctly etc to show only the x axis on top.

Easwar,
close call, it certainly creates a second axis, but it is not what I need. My primary x-axis has values from e.g. -50 to 250, while the secondary x-axis values go from e.g. 0 to 6000. There is a linear relationship between these two , but this relationship is different for every graph I have. In another graph, the primary x-values are the same while the secondary go only from 0 to 800. That is why I can't use the programming example where the relationship is set as fixed.
What I need is to use one set of x-values for the primary x-axis and the other set of x-values (which are in the same worksheet, but of course in a different column) for the secondary x-axis.
I hope I am not too unclear about what i need. |

Hi Ralph,
You can use code such as pasted below:
void show_top_axis()
{
GraphLayer gly = Project.ActiveLayer();
if( !gly ) return;
AxisObject aoX2;
aoX2 = gly.XAxis.AxisObjects(AXISOBJPOS_AXIS_SECOND);
gly.XAxis.AxisObjects(AXISOBJPOS_AXIS_SECOND).TopTicks.Show.nVal = 1;
gly.XAxis.AxisObjects(AXISOBJPOS_LABEL_SECOND).TopLabels.Show.nVal = 1;
gly.GetPage().Refresh(TRUE);
}
See the programming example "Manipulate Graph Axes" under the "Graphing" category on the folloing page for more details:
http://www.originlab.com/index.aspx?s=9&lm=71&pid=268
Another option of course is to create a custom tempalte with these settings already in place, and then create a new instance of that tempalte in your OC code, so you don't have to go thru the process of setting these things individually in code.

Easwar,
Thank you for the maximising help. The second x-axis has a linear relationship to the main x-axis. I would just like to show both of them.

Hi Ralph,
What do you mean by "a second x-value"? Do you mean the second axis has some nonlinear relationship to the main x-axis, such as described in this page?
http://www.originlab.com/www/support/resultstech.aspx?ID=1018&language=English
If the above is the case, then you can acheive adding such an axis from OC by issuing LT_execute commands following instructions on the above page.

Hi Ralph,
You don't need to use LT, can use the SetShow method of PageBase.
So, code such as:
void maximize_graph(string strGraphName)
{
GraphPage gpg(strGraphName);
if( !gpg ) return;
gpg.SetShow();
gpg.SetShow(PAGE_MAXIMIZED);
}
The reason I did a SetShow() with no argument first and then followed again with argument set to PAGE_MAXIMIZED is that otherwise if the page is hidden, it does not seem to work...we need to look into that...
