使用主題格式的表達式我正在嘗試將多個相似圖的格式設置為一個表達式,以便我可以更改代碼的單個部分來更新所有看起來相似的圖。 但是,我很難將其實現為代碼。 我包含了一個最小的工作示例,展示了我希望繪圖的外觀以及我希望我的代碼的外觀,存儲一段用於格式化的代碼和每個繪圖的緊湊代碼。 關於如何修改它以使其工作的任何想法? 我正在開發 JMP 15.2 版。
dt = New Table( "Minimal Working Example",
Add Rows( 400 ),
New Column( "X", Numeric, Set Values( Repeat( 1 :: 20, 20 ) ) ),
New Column( "Y", Numeric, Set Values( Sort Ascending( Shape( Repeat( 1 :: 20, 20 ), 1 ) ) ) ),
New Column( "Size", Numeric, <<FORMULA></FORMULA>
圖形腳本編寫回复:使用主題格式的表達式你好,
表達式處理功能強大,需要一些練習。 這是一個讓您入門的示例,但您需要閱讀 Eval()、Expr()、NameExpr()、Substitute()、Substitute Into() 等內容。
Names Default To Here(1);
//make a 5-column table
dt = astable((1::20)` || J(20,4,randominteger(0,20)));
//the x column will be the first column
xCol = column (dt, 1);
//the y columns will be the remaining columns
yColList = (dt << get column names())[2::ncol(dt)];
//write the graph builder script, wrapping it in an expression. Use _XXX_ format for things
//you'll be substituting later. Here, that is just the "y" variable for a particular graph.
gbExpr = expr(
dt << Graph Builder(
Variables( X( xcol ), Y( _Y_ ) ),
Elements( Points( X, Y, Legend( 8 ) ) ),
SendToReport(
Dispatch(
{},
"400",
ScaleBox,
{Legend Model(
8,
Properties(
0,
{gradient( {Color Theme( "White to Red" )} )},
Item ID( "Size", 1 )
)
)}
),
Dispatch(
{},
"400",
LegendBox,
{Legend Position( {8, [0, -1]} ), Legend Position( {0, -1} )}
)
)
);
);
//cycling through the items in yColList, we create a graph for each y variable vs the x variable.
//be sure to read up on Name Expr ( ), as it is needed here to prevent evaluation of the Graph
//Builder script... we just want the code itself... we don't want JMP to try to evaluate the code
//until after we've made the substitution.
for (i = 1,i <=nitems(ycolList), i++,
eval(Substitute( nameExpr(gbExpr), expr(_Y_) , expr(yColList[i])));
);
乾杯,

回复:使用主題格式的表達式由於 X、Y 和顏色變量在我的數據上變化的方式,這並沒有很好地工作,但是我設法使用 JSL Quote、Eval Insert、Parse 和 Eval 找到了更接近我想要的解決方案:
// A theme format I could change for a gazillion of plots
formats = JSL Quote(
SendToReport(
Dispatch(
{},
"400",
ScaleBox,
{Legend Model(
8,
Properties(
0,
{gradient( {Color Theme( "White to Red" )} )},
Item ID( "Size", 1 )
)
)}
),
Dispatch(
{},
"400",
LegendBox,
{Legend Position( {8, [0, -1]} ), Position( {0, -1} )}
)
)
);
// How I would like each plot code to look like
Eval(Parse(Eval Insert("dt << Graph Builder(
Variables( X( :X ), Y( :Y ), Color( :Size ) ),
Elements( Points( X, Y, Legend( 8 ) ) ),
^formats^
);")));
