-===== Setting Variables in Formulas =====+===== 1. New good-looking cross-platform interface ===== 
 + 
 +MagicPlot 3.0 utilizes the new unified interface style [[https://www.formdev.com/flatlaf/|FlatLaf]] on all supported operating systems. It is fully HiDPI/Retina display compatible. 
 + 
 +{{:release:new-interface.png?nolink|MagicPlot 3.0 new interface}} 
 + 
 +===== 2. New in expressions: Variables, comments, special functions and more ===== 
 + 
 +==== 2.1. Setting variables in expressions ====
  
 In MagicPlot 3.0 you can set variables in formulas: write an assignment and a semicolon to separate it from the next part of the formula, for example: ''a=5; a*a + 2*a + 1''. The last expression (after the last semicolon) is the result of the formula and cannot contain an assignment. MagicPlot highlights all usages of the variable at cursor in the edited formula. In MagicPlot 3.0 you can set variables in formulas: write an assignment and a semicolon to separate it from the next part of the formula, for example: ''a=5; a*a + 2*a + 1''. The last expression (after the last semicolon) is the result of the formula and cannot contain an assignment. MagicPlot highlights all usages of the variable at cursor in the edited formula.

-==== Tip: Inserting Fit Equation to the Column Formula ====+=== Tip: Inserting fit equation to the column formula ===
  
 You can copy the fit equation with variables from the Report tab of a Fit Plot and paste it in any formula field including Column Formula (but it is generally better to use new ''Add to Table'' feature which generates a link instead of copying formula, see below): You can copy the fit equation with variables from the Report tab of a Fit Plot and paste it in any formula field including Column Formula (but it is generally better to use new ''Add to Table'' feature which generates a link instead of copying formula, see below):

-===== Comments in Formulas =====+==== 2.2. Comments in expressions ====
  
 You can insert comments in any formula using ''/*...*/'' notation: You can insert comments in any formula using ''/*...*/'' notation:
  
-{{:release:formula_comments.png?nolink|}}+{{:release:formula_comments.png?nolink|Comments in expressions}}
  
-Use ''Ctrl+/'' / ''Cmd-/'' keyboard shortcut to comment selection. Comments can be multi-line. Note that the single line comments using a symbol at the line start (like ''%%//%%'' or ''%'') are not supported because line breaks are not taken into account in MagicPlot formula syntax.+Press ''Ctrl+/'' on Windows/Linux or ''Cmd-/'' on Mac OS to comment selection. Comments can be multi-line. Note that the single line comments using a symbol at the line start are not supported because line breaks are not taken into account in MagicPlot formula syntax.
  
-===== Simplified Column Formula Notation: $A for col(A) =====+==== 2.3. Bessel, Erf, Gamma, Beta special functions added ====
  
-We have simplified Column Formula syntax: column and cell values can be inserted using ''$A'' and ''$A$1'' instead of ''col(A)'' and ''cell(A, 1)''. The old notation also works.+The special functions listed below are now available in formulas. MagicPlot special function implementation is based on the well-known [[https://en.wikipedia.org/wiki/Colt_(libraries)|Colt 1.2]] scientific open-source library.
  
-The new notation only works with constant column/cell indexes. Use ''col'' and ''cell'' functions if you need to vary the index, ex. ''col(i)'' and ''cell(i-1, j+1)''.+^ Bessel functions ^^ 
 +| ''besselj(n, x)'' | Bessel function of the first kind of integer order n |  
 +| ''bessely(n, x)'' | Bessel function of the second kind of integer order n | 
 +| ''besseli(n, x)'' | Modified Bessel function of the first kind of order n = 0, 1 | 
 +| ''besselie(n, x)'' | Exponentially scaled modified Bessel function of the first kind of order n = 0, 1 | 
 +| ''besselk(n, x)'' | Modified Bessel function of the second kind of integer order n | 
 +| ''besselke(n, x)'' | Exponentially scaled modified Bessel function of the second kind of order n = 0, 1 | 
 +^ Error function ^^ 
 +| ''erf(x)'' | Error function | 
 +| ''erfc(x)'' | Complementary error function, 1 - erf(x) | 
 +^ Gamma function ^^ 
 +| ''gamma(x)'' | Gamma function | 
 +| ''gammainc(a, x)'' | Regularized lower incomplete gamma function. \\ x — the integration end point, a — the parameter of the gamma distribution |  
 +| ''gammaincc(a, x)'' | Regularized upper incomplete gamma function. \\ x — the integration start point, a — the parameter of the gamma distribution | 
 +| ''gammaln(x)'' | Logarithm of the absolute value of the gamma function |  
 +^ Beta function ^^ 
 +| ''beta(a, b)'' | Beta function. The values of a and b must be nonnegative | 
 +| ''betainc(x, a, b)'' | Incomplete beta function. \\ a, b — parameters of the beta function, must be nonnegative, \\ x — the integration end point, must be in the closed interval [0, 1] |
  
-{{:release:columns_in_formula.png?nolink|}}+==== 2.4. Miscellaneous functions added ====
  
-===== Setting a Formula for Multiple Columns =====+^ Reciprocal trigonometric functions ^^ 
 +| ''csc(x)'' | Cosecant of an angle measured in radians, csc(x) = 1/sin(x) | 
 +| ''sec(x)'' | Secant of an angle measured in radians, sec(x) = 1/cos(x) | 
 +| ''ctg(x)'' | Cotangent of an angle measured in radians, ctg(x) = 1/tan(x) | 
 +^ Other ^^ 
 +| ''xor(a, b)'' | Logical exclusive-OR operation | 
 +| ''rem(x, y)'' | Computes the remainder of the division operation x/y, same as ''x % y''. Added for compatibility | 
 +| ''isNaN(x)''  | Checks if x is NaN (Not a Number) or empty cell (see [[:NaN|manual topic]]) |
  
-The same formula can be set for multiple selected columns. You can use this feature to compute matrices. The ''i'' and ''j'' variables are the current row and column indexes.+==== 2.5. Improvements in Boolean operations ====
  
-===== Calculation in Reverse Row Order =====+=== The Boolean meaning of numbers in C language style ===
  
-You can swap ''from'' and ''to'' row indexes to reverse the calculation order. This can be useful if the cell formula contains the value of the previously calculated cell in the same column.+MagicPlot uses ordinary floating-point numbers to store Boolean ''true/false'' values. All Boolean operators and functions return ''1'' for ''true'' and ''0'' for ''false''. However the ''if()'' function can accept any number as a condition, not ''1'' and ''0'' only. In the old MagicPlot 2.x versions the condition value is interpreted as ''false'' if the value is less or equal to zero. In MagicPlot 3.0 only zero value is interpreted as ''false''. This change was made to synchronize specification with C-like languages. The change will only be notable if you manually used some calculated numbers as Boolean condition in a non-standard way.
  
-===== Undo/Redo in Formula Editor =====+^ App version ^ The result of ''if(condition, if_true, if_false)'' ^ 
 +| MagicPlot 3.0 and later | If ''condition != 0'' returns ''if_true'' value. Returns ''if_false'' value otherwize. | 
 +| MagicPlot 2.9.3 and earlier | If ''condition > 0'' returns ''if_true'' value. Returns ''if_false'' value otherwize. |
  
-MagicPlot now supports Undo and Redo in formula editor using ''Ctrl+Z'' / ''Cmd-Z'' (Undo) and ''Ctrl+Shift+Z'' / ''Cmd-Shift-Z'' or ''Ctrl+Y'' / ''Cmd-Y'' (Redo) shortcuts. 
  
-===== Optimized Table Scrolling and Redrawing =====+=== Negation operator (!) and exclusive or operator added ===
  
-We have optimized the program code of the redrawing of the Table to eliminate lags when scrolling and editing a Table with tens or hundreds of thousands of columns.+  * New negation operator example: ''f = $A > 0; if (!f, $A, $B)''.  
 +  * ''xor(a, b)'' returns the Boolean exclusive or operation result for operands.
  
-===== Special Functions in Formulas =====+==== 2.6. Undo/Redo in formula editor ====
  
-The special functions listed below are now available in formulas:+MagicPlot now supports Undo and Redo in formula editor using ''Ctrl+Z'' / ''Cmd-Z'' (Undo) and ''Ctrl+Shift+Z'' / ''Cmd-Shift-Z'' or ''Ctrl+Y'' / ''Cmd-Y'' (Redo) shortcuts.
  
-  * besselj(n, x) 
-  * bessely(n, x) 
-  * besseli(n, x), n = 0, 1 
-  * besselie(n, x), n = 0, 1 
-  * besselk(n, x) 
-  * besselke(n, x), n = 0, 1 
  
-  * erf(x) +===== 3. Improvements in Tables: $A notation, formula for multiple columns and more =====
-  * erfc(x)+
  
-  * gamma(x) +==== 3.1. Simplified column formula notation: '$A' instead of 'col(A)' ====
-  * gammainc(a, x) +
-  * gammaincc(a, x) +
-  * gammaln(x)+
  
-  * beta(a, b) +We have simplified Column Formula syntax: column and cell values can be inserted using ''$A'' and ''$A$1'' instead of ''col(A)'' and ''cell(A, 1)''. The old notation also works.
-  * betainc(x, a, b)+
  
-MagicPlot uses Colt library for special function implementation. Some boundary and asymptotic values were corrected after the Colt library results.+The new notation only works with constant column/cell indexes. Use ''col'' and ''cell'' functions if you need to vary the index, ex. ''col(i)'' and ''cell(i-1, j+1)''.
  
-===== Improvements in Boolean Operations =====+{{:release:columns_in_formula.png?nolink|New column formula syntax: $A}}
  
-==== Standard Boolean Logic: true is != 0 instead of > 0 ====+==== 3.2. Setting a common formula for multiple columns ====
  
-MagicPlot uses ordinary floating-point numbers to store boolean ''true/false'' values. All boolean operators and functions return ''1'' for ''true'' and ''0'' for ''false''. However the ''if()'' function can accept any number as a condition, not ''1'' and ''0'' only. In the old MagicPlot 2.x versions the condition value is interpreted as ''false'' if the value is less or equal to zero. In MagicPlot 3.0 only zero value is interpreted as ''false''. This change was made to synchronize specification with C-like languages. The change will only be notable if you manually used some calculated numbers as boolean condition in a non-standard way.+The same formula can be set for multiple selected columns. You can use this feature to compute matrices. The ''i'' and ''j'' variables are the current row and column indexes.
  
-==== Negation Operator (!) Added ====+==== 3.3. Calculation in reverse row order ====
  
-We have added negation operator with well-known syntax ''!'' to the expression syntax. Example: ''if (!($A > 0), $A, $B)''. +You can swap ''from'' and ''to'' row indexes to reverse the calculation order. This can be useful if the cell formula contains the value of the previously calculated cell in the same column.
- +
-==== Exclusive or Operator Added ====+
  
-''xor(a, b)'' returns the boolean exclusive or operation result for operands.+==== 3.4. Optimized table scrolling and redrawing ====
  
-===== No more 'Data-Baseline' Column =====+We have optimized the program code of the redrawing of the Table to eliminate lags when scrolling and editing a Table with hundreds of thousands of columns.
  
-Staring MagicPlot 3.0 The 'Data-Baseline' column is no more added to the Table when creating a Fit Plot. The 'Data-Baseline' column contained the Y values from the Fit Plot with the baseline curves subtracted -- the Y values that are actually plotted. This feature was introduced in the early MagicPlot version but it has proved to be mostly annoying.+===== 4. Fit results management: Adding curves to table, no 'Data-Baseline' column =====
  
-The 'Data-Baseline' auto-recalculated columns will be preserved when opening old projects in MagicPlot 3.0 for backward compatibility. You can delete these columns manually. +==== 4.1. Adding fit sum and fit curve column to the table ====
- +
-Now you can manually create the 'Data-Baseline' column among with other fit result columns using the Fit Report tab of a Fit Plot, choose ''Y with baseline corrected'' and click on ''Add to Table'' button: +

-===== Adding Fit Sum and Fit Curve Column to the Table =====+
  
 You can now add a column with Fit Sum or other alternatives to the Table which contains Fit Plot data using ''Fit Report'' tab. The alternatives are: Fit Sum, Baseline, Y with baseline corrected, Residual: You can now add a column with Fit Sum or other alternatives to the Table which contains Fit Plot data using ''Fit Report'' tab.

-===== Changes in Keyboard Shortcuts =====+==== 4.2. 'Data-Baseline' column is not automatically created ====
  
-  * The keyboard shortcut for Undo History was changed to ''Ctrl+Shift+H'' / ''Shift-Cmd-H''. +Staring MagicPlot 3.0 The 'Data-Baseline' column is no more added to the Table when creating a Fit Plot. The 'Data-Baseline' column contained the Y values from the Fit Plot with the baseline curves subtracted -- the Y values that are actually plotted. This feature was introduced in the early MagicPlot version and it has proved to be rarely used. 
-  * A new shortcut for creating a Folder was added: ''Ctrl+Shift+N'' / ''Shift-Cmd-N''.+ 
 +The 'Data-Baseline' auto-recalculated columns in old projects will be preserved when opening in MagicPlot 3.0 for backward compatibility. In MagicPlot 3.0 you can delete these columns manually.
