Improve box plot in One-Way ANOVA

1. For the box charts of One Way ANOVA and Statistic on columns, which has only one group column, Origin 2020 does not set subgroup.
2. One Way ANOVA's box charts and Statistic on columns' box charts default templates follow Grouped Box Charts' setting in Plot Details dialog:
   1. Check Outliers checkbox and Box width=80 in Box tab.
   2. Uncheck 99% and 1%, Max, Min checkboxes in Percentile tab
   3. Border Color=Q13 and width=1.5, Fill Color: Auto in Pattern tab
   4. Caps Length=50 in Lines tab
3. Rename Connect by Subgroup to Connect within Subgroup in Plot Details dialog Connect Lines tab for Grouped Box Charts

Set Cluster Membership column as Categorical and Ascending type

In Origin 2019b, K-Means Cluster Analysis and Hierarchical Cluster Analysis, Cluster Membership column was already sorted and without link to the order of the original data.

In Origin 2020, K-Means Cluster Analysis and Hierarchical Cluster Analysis, Cluster Membership column keeps  the order of the original data and is set as Categorical and Ascending type.

Speed improvements on Means Comparison in ANOVA tool

Improved the calculating speed of Means Comparison, and it will be 30% faster than Origin 2019b.

Besides, if choose not output the Means Comparison result, previous version will still do the calculation in background and waste time. Now this is fixed in Origin 2020, and will be 83 times faster than Origin 2019b.

Control Polygon or Polyline object thru LabTalk

• <objectName>.PointCount

Suppose user has a polygon of 4 points, then script "polygon.pointcount =;" will return 4.

Also, can set polygon.pointcount=5 to add more points, then use polygon.x5= and polygon.y5= to specify the 5th point coordinates.

• Get and Set XY coordinates to/from worksheet columns

// objname.GetXY(xDataset, yDataset); // copy from obj to dataset
// objname.SetXY(xDataset, yDataset); // copy from dataset to obj
// Ex:
polyline.getXY(book1_a, book1_b);
polyline.setXY(book2_a, book2_b);
polyline.getXY(book1_a); // copy only X values
polyline.getXY(, book1_b); // copy only Y values

• Also when adding polygon, polyline, ESC will finish it.

Faster Date and Time LabTalk functions

Origin Labtalk functions belong to Date and Time category are moved to VC level to have faster speed.

E.g.

Column A is filled with 1million rows of date data

Set Column B formula as WeekDayName(A)

In Origin 2019b and earlier build, it took about 95 sec, while in Origin 2020, it only takes about 1 sec.

Note: In Set Column Values dialog, you can click Function: Date and Time menu to see all date and time functions Origin supports.

LabTalk option to generate gadget output for all curves, all layers, etc.

We had the following to generate new output of a gadget.
Gadget gd = Rect;
gd.Output();

But since we have New Output for All Curves, New Output for All Layers, etc., we should have more options of what to output.
So now user can use
gd.Output(2) //new output for all curves

0 -- normal
1 -- last
2 -- all curves
3 -- all layers
4 -- entire curve //this is Quick Peaks gadget only

LT command to reduce file size

Labtalk command file -cp is very useful to reduce a huge data file, E.g. a 14G CSV file, you cannot open it anywhere. You can reduce it to a manageable size first. The code is like this

dlgfile g:=*.csv;
file -cp 3Mb fname$;

to reduce it to 3Mb.

Origin C OC and LT Access to Data Connector

1. OC call LT Sub method in Page level, for example:

void test()
{
WorksheetPage wp = Project.Pages();
int nErr = wp.DoMethod("DC.Add", "CSV");
}

2. Support "wbook.DC.type$" to get the DC type.

3. Simpler syntax for web connector in LT, for example:

newbook;
wbook.dc.add("JSON");
wks.dc.source$="https://earthquake.usgs.gov/fdsnws/event/1/query?format=geojson&starttime=2018-01-01&endtime=2018-01-23"; 
wks.DC.Sel$="JSON/features";
wks.dc.import();

Support numeric access to label cell

When label cell is a numeric value, you can access it as numeric value instead of string now. 

E.g, 

col(A)[D1] =;

This can be disable by setting @LRNA = 0.

Support simple LT expression in Add Straight Line and other XFs

• Support LT Expression for Value, e.g. enter -log(0.05)
• Support Page info variables and values from columns as input to XF, e.g. page.info.user.variables.noofpoints

Convert floating-point from other formats to IEEE 754

Added following OC funtion to convert floating-point from other formats to IEEE 754.

typedef enum
{
	FLOATING_POINT_TYPE_IEEE_FLOAT = 0,   // 32-bit
	FLOATING_POINT_TYPE_IEEE_DOUBLE,      // 64-bit

	FLOATING_POINT_TYPE_VAX_F,            // 32-bit, ~[-2.9E-39, 1.7E+38]
	FLOATING_POINT_TYPE_VAX_D,            // 64-bit, ~[-2.9E-39, 1.7E+38]
	FLOATING_POINT_TYPE_VAX_G,            // 64-bit, ~[-5.6E-309, 0.9E+308]

	FLOATING_POINT_TYPE_IBM_SHORT,        // 32-bit
	FLOATING_POINT_TYPE_IBM_LONG,         // 64-bit
	FLOATING_POINT_TYPE_IBM_LONG_XPORT,   // 64-bit

	FLOATING_POINT_TYPE_COUNT
} FLOATING_POINT_TYPE;

bool convert_floating_by_format(LPVOID lpOutputBuff, LPVOID lpInputBuff, size_t nNumValues, FLOATING_POINT_TYPE nOutputFormatType, FLOATING_POINT_TYPE nInputFormatType);

For example:
void vax_test()
{
	unsigned int a[] = {0x268bc2d9, 0x015dc2d9};
	double f[2];
	convert_floating_by_format(f, a, 2, FLOATING_POINT_TYPE_IEEE_DOUBLE, FLOATING_POINT_TYPE_VAX_F);
	// f = { -27.14381980895996, -27.12566566467285 }
	return;
