Unwanted re-evaluation of a variable inside Manipulate
$begingroup$
In the below Manipulate expression:
Discretize=Function[{f,steps,x1},Table[f[x],{x,0,x1,Floor[x1/steps]}]];
MakePoints=Function[var,Table[x^2+RandomReal[{-var,var}],{x,0,15,1}]];
Manipulate[
GetDiff = Function[
Total[dta] - Total[mdl]
];
dta = MakePoints[15];
mdl = Discretize[Function[x, τ*x^2], Length[dta] - 1,
Length[dta] - 1];
ListLinePlot[{dta, mdl},
PlotRange -> {{0, Length[dta] - 1}, {0, 250}},
PlotLegends -> {"data", "model"}],
{{τ, 1}, .01, 3, .01},
Dynamic[
diff = GetDiff;
"τ: " <> ToString[τ] <>
"nΣdata: " <> ToString[Total[dta]] <>
"nΣmodel: " <> ToString[Total[mdl]] <>
"nΣdata-Σmodel: " <> ToString[diff]
]
]
Why does varying the parameter seemingly reevaluate dta
? I get a constantly changing dta
line while I vary the parameter.

Your MakePoints[ ]
function has a RandomReal[ ]
function call in it, so it is randomizing each time you move the Manipulate slider. Just move it outside.
dta = MakePoints[15];
Manipulate[GetDiff = Function[Total[dta] - Total[mdl]];
(*dta=MakePoints[15];*)
...Etc.]
or you can wrap the internal random call with a BlockRandom[ ]
Manipulate[GetDiff = Function[Total[dta] - Total[mdl]];
dta = BlockRandom@MakePoints[15];
.... Etc. ]

Your code can be fixed and made much simpler and more efficient, all at the same time. Like so;
Discretize = Function[{f, steps, x1}, Table[f[x], {x, 0, x1, Floor[x1/steps]}]];
MakePoints = Function[var, Table[x^2 + RandomReal[{-var, var}], {x, 0, 15, 1}]];
SeedRandom[1];
Manipulate[
mdl = Discretize[Function[x, τ x^2], Length[dta] - 1, Length[dta] - 1];
tmdl = Total[mdl];
Column[{
ListLinePlot[{dta, mdl},
PlotRange -> {{0, Length[dta] - 1}, {0, 250}},
PlotLegends -> {"data", "model"},
ImageSize -> Medium],
Row[{"Σdata: ", tdta}],
Row[{"Σmodel: ", tmdl}],
Row[{"Σdata-Σmodel: ", tdta - tmdl}]}],
{{dta, MakePoints[15]}, None},
{{tdta, Total[dta]}, None},
{mdl, None},
{tmdl, None},
{{τ, 1}, .01, 3, .01, Appearance -> "Labeled"},
TrackedSymbols :> {τ}]]
Notes
GetDiff
is not needed.- Introducing some local variables with specifications of the form
{varspec, None}
, which are automatically dynamic, makes for cleaner code and makes it easy to set static values fordata
andtdta
. - Calling
MakePoints
as an initializer in the specification ofdta
fixes you problem of unwanted re-evaluation. - Only
τ
need be tracked, which reduces the load on the front-end. - Introducing
Column
andRow
much simplifies the formatting of the output. - Adding the
Appearance -> "Labeled"
option to the specification ofτ
eliminates the need to write code to showτ
in the output, - This approach does not require calling
Dynamic

Another option using DynamicModule
which is the proper tool for interfaces that have local variables:
DynamicModule[
{MakePoints, Discretize, dta, tdta, mdl, tmdl},
Manipulate[
mdl = Discretize[Function[x, τ x^2], Length[dta] - 1,
Length[dta] - 1];
tmdl = Total[mdl];
Grid[
{
{
ListLinePlot[
{dta, mdl},
PlotRange -> {{0, Length[dta] - 1}, {All, 250}},
PlotLegends -> {"data", "model"}, ImageSize -> Medium
],
SpanFromLeft
},
{Subscript["Σ", "data"], ":", tdta},
{Subscript["Σ", "model"], ":", tmdl},
{
Row@{Subscript["Σ", "data"], "-",
Subscript["Σ", "model"]}, ":",
tdta - tmdl
}
},
Alignment -> Left
],
{{τ, 1}, .01, 3, .01, Appearance -> "Labeled"},
TrackedSymbols :> {τ}
],
Initialization :> {
MakePoints =
Function[var, Range[0, 15]^2 + RandomReal[{-var, var}, 16]],
Discretize =
Function[{f, steps, x1}, Table[f[x], {x, 0, x1, Floor[x1/steps]}]],

Initialization :> {
MakePoints =
Function[var, Range[0, 15]^2 + RandomReal[{-var, var}, 16]],

Another option using DynamicModule
which is the proper tool for interfaces that have local variables:
DynamicModule[
{MakePoints, Discretize, dta, tdta, mdl, tmdl},
Manipulate[
mdl = Discretize[Function[x, τ x^2], Length[dta] - 1,
Length[dta] - 1];
tmdl = Total[mdl];
Grid[
{
{
ListLinePlot[
{dta, mdl},
PlotRange -> {{0, Length[dta] - 1}, {All, 250}},
PlotLegends -> {"data", "model"}, ImageSize -> Medium
],
SpanFromLeft
},
{Subscript["Σ", "data"], ":", tdta},
{Subscript["Σ", "model"], ":", tmdl},
{
Row@{Subscript["Σ", "data"], "-",
Subscript["Σ", "model"]}, ":",
tdta - tmdl
}
},
Alignment -> Left
],
{{τ, 1}, .01, 3, .01, Appearance -> "Labeled"},
TrackedSymbols :> {τ}
],
Initialization :> {
MakePoints =
Function[var, Range[0, 15]^2 + RandomReal[{-var, var}, 16]],
Discretize =
Function[{f, steps, x1}, Table[f[x], {x, 0, x1, Floor[x1/steps]}]],
dta = MakePoints[15],
tdta = Total[dta]
