Google Sheets Scripts and Trendlines -

-

this question first scripts, because missing something. looking implementing them. when go "script editor" have create new "project" , save something. should script not attached spreadsheet?

but if ignore strange fact , open editor , copy , paste nice script in there, how run in spreadsheet? can see if go spreadsheet , refresh page new menu item appears, makes me think script running, script saved? overview of going on in google scripts awesome.

the overall problem attempting solve: want spreadsheets able plot trendlines. thought solution write script , apply spreadsheets. ideal script have menu item trendlines, , allow me select data need trendline. have advice or scripts this? not programmer can learn basics if need to. feature should exist. can't remember ever making scatterplot , not plotting trend , equation. help.

first of all, you're asking lot of questions.

as commented above zig mandel, need read documentation first.

here links documentation pages underway:

google spreadsheet documentation

google sheet documentation

google range documentation

i don't know how experience have or sort of background have, it's hard comment on do. seasoned dev or techie know parts of api he/she use. perhaps can start small example such colouring range of cells.

in regards copying , pasting pre-made script:

the premade script anything. it's bad example. creating menu item not constitute script being correct or running. menu created when document opens, , in function called "onopen()."

try starting new project, , planning want do. play around features seem apply, such getactiverange(), getrange(), getsheets(), getactivespreadsheet(); starters.

in regards custom menu, try (after have idea what's going on):

https://developers.google.com/apps-script/guides/menus

for exact problem, couldn't have done nothing graphs in google apps script, seem diving deep end , think above points point in right direction.

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
