@mattfox said in ma-point-value: number formatting:
point.value.toFixed(1)
you can also use a built-in Angular filter -
{{point.value | number(decimal places)}}
...even when doing things you can't do more than basics - like
{{point.value*256 | number(1)}}
edit. Jared Wiltshire - examples given here are incorrect, see post by @Puckfist below.
Thanks, @Jared-Wiltshire. The problem seems to be as follows:
If started from root (which I don't want to do, of course) with the --no-sandbox switch, everything works fine.
if started from regular user, it appears there is an X server bug -
Fatal server error:
(EE) parse_vt_settings: Cannot open /dev/tty0 (Permission denied)
Dealt with permissions, but then another similar permissions error...
After fixing permissions on the tty files, it works now without having to run as root.
Any experience with minimal Firefox kiosk use? Couldn't find much of value out there. Thanks again.
edit: for anyone who comes across this, and keeping in mind that I have only vague knowledge of how xserver works, the environment needs access to a number of /dev/tty files. I had to change permissions (a+rw) in tty files in 3 successive attempts, until successful. In my case it was tty0, tty7, tty2. This is specific at least to xorg compiled with raspberian stretch lite as of 12/20/2018.
@jared-wiltshire said in amCharts - maTankLevel center chart column in div:
marginRight: -74
Aha! Thank you Jared! I was barking up another tree... sorry for all the code - TMI
Thanks for all the help.
so WE did! same problem tho.
lets take this back to chat...
ok, @MattFox... I feel like a post (as in dumb as one). Can you refresh me again as to how to now break out (and where to declare) the component's controller in its own file?
userModule.js
define(['angular', 'require','./push/pushLamp.js'],
function (angular, require, pushLamp) {
var userModule = angular.module('userModule', ['maUiApp']);
userModule.filter('unsafe', ['$sce', function($sce) {
return $sce.trustAsHtml;
}]);
try
{
userModule.component('pushLamp',pushLamp);
}
catch(e)
{
console.log('error: ', e);
}
return userModule.js;
});
pushLamp.js:
define(['angular', 'require'], function (angular, require) {
pushCtrl.$inject = ['$scope','$timeout'];
function pushCtrl($scope,$timeout) {
const $ctrl = this;
$ctrl.$onChanges = function (changes) {
if (changes.points && Array.isArray($ctrl.points)) {
$ctrl.point = $ctrl.points.find(p => p.xid === 'DP_ind_' + $ctrl.target);
$ctrl.switchPoint = $ctrl.points.find(p => p.xid === 'DP_sw_' + $ctrl.target);
$ctrl.ptCSS = { // point css values for color and blink; ex, ng-class=""
get color(){
if ($ctrl.point.color < 10) {
return 0;
}
return Math.floor($ctrl.point.value / 10)},
get blink(){return 'blink' + $ctrl.point.value % 10},
get colStyle(){return 'color'+this.color}
};
$timeout(function() {
console.log('color:', $ctrl.ptCSS.colStyle, 'blink:', $ctrl.ptCSS.blink );
},1000);
}
};
$ctrl.pushed = function() {
console.log($ctrl.switchPoint.value);
if ($ctrl.switchPoint) {
$ctrl.switchPoint.toggleValue();
console.log('switch ' + $ctrl.target + ' was switched.' );
}
};
}
return {
templateUrl: '/modules/mangoUI/web/dev/push/push.html',
bindings: {
points: '<',
target: '@'
},
controller: pushCtrl
};
});@MattFox - Case closed. I stupidly put a non-specific div {...text-align:center}in one of my css files. Probably would have caught that, but the ace_text-layer width (& height) is set at 1000000px in ace/css/ace_editor.css, and height is further set to 1e+06px inline.
After much searching, I'm unable to find an example of why one would want to do that - although there must be one! Interestingly Chrome was rendering veeerrry slowly - when I lowered the width to 10000px, it sped up markedly.
We want to use a jquery plugin (jqSimpleConnect.js) to draw div connector lines; As we don't have access to the angularjs environment in designer per se, is there a preferred way to (1) wrap a jQuery plugin in a directive/component and (2) declare the external js file?
I believe I read that you do load jQuery in your .app. Thanks - sorry if this has been answered elsewhere - couldn't find it.

Ah... but of course you knew all that. Short answer is yes!
...confirmed it parses the pasted html at paste time. If I add a color: class to any of the spans, it's not read.
well, not exactly. Ace appears to parse out the JSON into 'lines', concatenated with spans:
<div class="ace_line" style="height: 30px;">
<span class="ace_meta ace_tag ace_punctuation ace_tag-open ace_xml"><
</span>
<span class="ace_meta ace_tag ace_tag-name ace_xml">div</span>
<span class="ace_text ace_tag-whitespace ace_xml"> </span>
<span class="ace_entity ace_other ace_attribute-name ace_xml">class</span>
<span class="ace_keyword ace_operator ace_attribute-equals ace_xml">=

@MattFox oops sorry... it only showed the warnings prior to this iteration...

@MattFox - posted issue in Mango Feedback, should you have any thoughts.
