Live charts in Excel: for future dates, lines drop to zero -

-

i run live market charts in excel. graph indicator runs live data fed broker through dde facility in microsoft excel. works fine , happy - except 1 blemish hope can assist with.

the lines of graph (it line chart type) created in real time. present time , past time great, clean. unfortunately in period ahead i.e. hasn't arrived yet, lines of graph drop 0 , crawl along x-axis future. spoils current reading of graph.

is there way can prevent happening lines (properly called curves) exist in past , current time period. worksheet set not show 0 values in formulae, charting facility not appear have function.

if put #n/a in cell (using =na() function) points not drawn.

to hide ugliness of cells having #n/a in them future dates can use number format or conditional formatting hide error values. adding formula conditional formatting of

=isna(a1)

and setting format white font on white background. makes cells #n/a in them appear blank. versions of excel prior conditional formatting being available can same thing number format in reverse. i.e., set font white cells invisible default , set number format to:

[black]0.0;[red]-0.0;[black]0.0;[black]

which should make isn't error appear either black or red font colour. regards

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
