invalid matrix token

h_lazar

Can someone tell me what the error "invalid matrix token" means? I am using the following script in a for loop (j as iterator) in order to graph and add a box for limits. However, the script is giving me the matrix error. Can someone give me a hint?

dgb=Bivariate(
Y(Column(yPlot)),
X(Column(xPlot)),
SendToReport(
Dispatch({}, "1", ScaleBox, {Max(xmax), Min(xmin)}),
Dispatch({}, "2", ScaleBox, {Max(ymax), Min(ymin)}),
Dispatch({},"Bivar Plot",FrameBox,
Add Graphics Script(
2,
Description("Script"),
Transparency(0.5);
FillColor({0.38, 0.84, 0.67});
Polygon([xLL,xLL,xUL,xUL], [yLL,yLL,yUL,yUL]);
)
)
)
);

xLL,xLL,xUL,xUL,yLL,yLL,yUL,and yUL are matrices of numbers. It also seems that this will not put the numbers in the script to the graph. Does anyone know how to do this?

So I figured out I had to use substitute but this still does not place the numbers in the script for the plot. Anyone have any ideas?

db=Bivariate(
Y(Column(yPlot)),
X(Column(xPlot)),
//invisible,
SendToReport(
Dispatch({}, "1", ScaleBox, {Max(xmax), Min(xmin)}),
Dispatch({}, "2", ScaleBox, {Max(ymax), Min(ymin)}),
Dispatch({},"Bivar Plot",FrameBox,
Add Graphics Script(2,
Description("Targets and Limits"),
PenColor("black");
PenSize(2);
Eval(Substitute(Expr(Line({xt1,y11},{xt1,y22})),
expr(xt1),xT,expr(y11),yLL,expr(y22),yUL));
Eval(Substitute(Expr(Line({x11,yt1},{x22,yt1})),
expr(x11),xLL,expr(yt1),yT,expr(x22),xUL));
Transparency(0.15);
FillColor(66);
Eval(Substitute(Expr(Polygon(
matrix({x11, x11, x22, x22}),matrix({y11, y22, y22, y11}))),
expr(x11),xLL,
expr(x22),xUL
expr(y11),yLL,
expr(y22),yUL))
);
);
);
);
);

does anyone have an answer to this? how do you script and "add graphics script" to a platform graph and insert values for variables?

thanks

I've tried loading this script to try it out for myself, but there are a couple of errors in it (there's a comma missing at the end of the "expr(x22)" line plus one mismatched bracket at the end). Correcting these as I'm assuming they should be corrected gives the program below, which I've tried running on one of the supplied data sets as shown: it crashes because it doesn't know what "xT" is. I can see another reason it might not work, namely that xmax, xmin, ymax and ymin aren't defined in this data set, but since I don't have your data I don't know what values these should take:

Another thought: the problem looks as if it involves inserting numbers into the script as opposed to variable names. In such cases I usually create a block of text which contains the script I know I want to run, and then parse it.

For example, suppose I wanted to add a property called "Cutoff" to the "Height" column of Big Class, and I wanted the value of Cutoff to be whatever number is held in a variable called CutoffValue, which is currently 60. My first guess might be to do it like this:

CutoffValue = 60;
dt = open("$SAMPLE_DATA/Big Class.jmp");
column(dt, "Height") << set property(Cutoff, CutoffValue);

That doesn't work however: if you inspect the properties of the "Height" column, all you see is "CutoffValue". One way out is to use eval, as you've done several times in your script:

column(dt, "Height") << set property(Cutoff, eval(CutoffValue));

Alternatively, try setting up something like this:

TextToParse = "column(dt, \!"Height\!") << set property(Cutoff, " || char(CutoffValue) || ");";
show(TextToParse);
eval(parse(TextToParse));

The advantage of the above is that if it still isn't working, at least you can write the expression to the log to make sure you've got the syntax right. I sometimes write entire blocks of script like this when they get seriously complicated: perhaps you could do something similar with your script too.
