CHT_DMS

This command uses a DMS chart or Desktop to create an HTML file and returns the name and location of this HTML file. It also provides the names and locations of any supporting files that are needed by the HTML file.

Syntax

CHT_DMS "chart_style", chart_type, "array_name"

The combination of "chart_style" and chart_type parameters specifies the type of chart to generate or specifies that a Desktop will be retrieved. Valid options for these parameters are:

chart_style	explanation
P	Pareto chart
D	DPU chart
C	Control chart
any string (including a blank string "")	Desktop

chart_style

11	Defects per Unit
12	Sigma

* If the default setting for cost statistics is Bypass cost to improve speed, the CHT_DMS command cannot generate these cost-based charts.

The "array_name" parameter is used to determine which processes or standards to chart or which Desktop to retrieve. Valid options for this parameter are:

array_name

explanation

blank

Chart all processes and part numbers.

name of a MySArr

Before executing the CHT_DMS command, use the MYSARR command to do one of the following:

• If you are retrieving a Desktop, set the value of MYSARR "array_name", 1 equal to the name of the Desktop you want to retrieve.

• If you are drawing a chart for one or more processes, set the value of MYSARR "array_name", 1 equal to the name of the first process; MYSARR "array_name", 2 equal to the name of the second process; etc.
This option is valid for the Pareto and DPU chart styles. It is not valid for the Control chart style.

• If you are drawing a chart for one or more standards, set the value of MYSARR "array_name", 1 equal to the name of the first DMS standard; MYSARR "array_name", 2 equal to the name of the second DMS standard; etc.

For the Control chart style, this will generate a separate chart for each standard in the array. For the Pareto and DPU chart styles, this will generate one chart that includes data from all standards in the array.

There are two valid ways to format these DMS standard names:

o Part Number, followed by the Tab character (CHR 9), then followed by the Process

o Part Number padded with spaces (if necessary) to make it 30 characters long, followed by the Process

Return value

This command returns a string that contains the name and location of the HTML file it has created.

If the specified chart could not be generated, this command returns an empty string.

Notes

Additional options for sending DMS charts to HTML are set by the CHT_OPT_DMS command.

For any supporting files (e.g., *.jpg, *.gif, *.htm) that are needed by this HTML file, the CHT_DMS command also sets the value of MYSARR "Cht_DMS_Support", 1 equal to the name of the first supporting file; MYSARR "Cht_DMS_Support", 2 equal to the name of the second supporting file; etc. It also sets the value of MYSARR "Cht_DMS_Support", 0 equal to the location of these supporting files.

If you specify a Control chart for a MYSARR that references multiple standards, the CHT_DMS command will generate one HTML file for each chart and one additional HTML file containing links to the HTML files for the charts. After the user clicks a link to view the chart, they can click the chart window's button to return to the page containing the links.

If the specified chart could not be generated, the CHT_DMS command puts the error message in a string variable named MySVar "Chart_Error".

If you find that the focus does not returns to the SPC Data Entry module after executing this command, use the formula PBUFF : CLOSE_PBUFF to return the focus to the SPC Data Entry module.

Note: If this command is executed when the DMS Charts and Reports module is already open on the workstation, it will close the DMS Charts and Reports module.
