I have multiple charts on a html page, and a single fex I do an -INCLUDE on each chart to set my parameters for the chart in focus at runtime.

When I add the first chart to my page (GUI), I'm prompted to create controls for my chart. Then, when I go to add my next chart, I want a separate set of controls that will only change the chart above it. But, because my parameters are the same name (single fex with parameters), I don't get prompted to add these new controls.

One way I've thought of doing this is naming my parameters dynamically like below, but I can't get it to work:

-SET &ECHO=ALL;
-DEFAULT &CHT='_CHT_A'

-SET &SORTORD|&CHT='INVERT';

I want the line above to read:

-SET &SORTORD_CHT_A='INVERT';

Can anyone assist in what I need to do? I feel it's obvious, but I'm still missing it...Thanks!

A dynamic parameter as you stated (-SET &SORTORD|&CHT) can only exist at run time. So it is "normal" that the GUI is not aware if its existence.

I'm wondering one thing : why would you like to include several charts on a same HTML page of they all have different update parameters ?
It's going to be a nightmare to associate the proper parameter with the proper chart : and I'm not talking of programming side but user side.
They will have to figure that if they change param-1 it will update chat-1, param-2 for charts-2 and param-3 for chart-1 and chart-2 ?
It may be your need, but I found it confusing.

As far as I can know without doing a lot of research, you will need to have distinct parameter per chart.

Or a thing that you can do is to keep the unique parameter's name in the charts but have your main fex with the distinct one.

-* Main fex to call chart A and receive parameters from HTML
-* -------------------------------------
-SET &ECHO=ALL;
-DEFAULTH &SORTORD = ''
-DEFAULT &SORTORD_CHT_A = 'INVERT'

-SET &SORTORD = &SORTORD_CHT_A;
-INCLUDE app/CHART_A.fex



-* Main fex to call chart B and receive parameters from HTML
-* -------------------------------------
-SET &ECHO=ALL;
-DEFAULTH &SORTORD = ''
-DEFAULT &SORTORD_CHT_B = 'REGULAR'

-SET &SORTORD = &SORTORD_CHT_B;
-INCLUDE app/CHART_B.fex

Having the main 2 fex in your HTML should then popup for distinct parameters but your charts keep unique one.
Do not reference the charts in your HTML, but the above fex.

You can use a . ( period ) for that.

-SET &A = 1;
-SET &PARAM.&A = 'this is a';

-SET &A = 2;
-SET &PARAM.&A = 'this is b';


-SET &A = 1;
-TYPE &PARAM.&A
-SET &A = 2;
-TYPE &PARAM.&A

Instead of dynamic naming, for simplicity and clarity I would prefer to create a driver fex for each of the respective charts on the page, with distinct parameters.

  • Chart A would call driver A, whose parameters are those of the common charting fex but with A appended to the parameter names; to generate the chart it sets the common fex's parameters to the corresponding ones it receives...
    -DEFAULT &SORTORDA='...';
-SET &SORTORD=&SORTORDA;
    and so on for the other paranmeters;
    and then -INCLUDEs the common charting fex.

  • Similarly for charts B, C, ....


In the common charting fex, adjust the -DEFAULT/-DEFAULTH directives so they won't trigger creation of controls for its parameters.

And let nature take its course.
