XR - XMR Line graph - make use of app variables

[ThierryC]

I'm testing the ability and function of the line graph within Nitra app for usage in production. the idea is to use it for entering XR / XMR data

to give some background
Upon product design - together with customer- tolerances are defined for certain dimensions .. currently this is still done in Excel - based on the tolerances a blank chart is printed,
handed over to operators that need to measure on a fixed frequency and draw this manually by pen on the excel paper (!!!)
No need to tell that this can be improved a lot

since this is really open for errors, nor has the possibility to push the operators into some actions when the measure is outside the tolerances, i was thinking of creating this in Valence nitro apps..

one app that would be the database, maintained by quality personnel, containing the dimensions and the tolerances...
the other app would be for the operators to enter the measured data...

the taken measures should be possible to visualize on a graph


When playing around with the charts.. I think all is possible, however i feel functions are missing to make it really usable.

1. Maximum - minimum values is now hardcoded..
   currently when leaving the min-max values blank (and letting nitro self auto -choose.. it uses the max value from the data as the upper line, leaving no whitespace at the top and thus making it more difficult for reading the graph
   
   
   i would be good if this was controllable via app-variables.. when choosing an article, i could f.e take the max - min out of de database and add-subtract f.e 5%
   PS. it looks like for the lower value it leaves some margin.. but not for the upper (see attached image)
2. Title.. - subtitle
   title is now fixed-hard-coded- .. is there a way to also have this controlled via an app - or database variables ? - so that i can display in the title the selected article
3. Tool tip -
   i've tried to add Html for forcing a line-break- but seems not possible
   
   would be great if this was made possible

as example master database containing measures and tolerances per article

Article	should be dimension	upper tolerance allowed	Lower tol. allowed
20202697	70.00	70.15	69.85

registration of the operator an the real measured dimension

Article	Sequence	measured data
20202697	1	70.10
20202697	2	70.11
20202697	3	69.90
20202697	4	69.89
20202697	5	69.92
20202697	6	70.12

(1) = fixed title - should be made accepting a database variable
(2) = upper value - no margin is left
(3) =lower value : make it controllable via app variable
(4) = tooltip - to accept html

thx considering these changes,.. (of give your view - work-around) on the problem

Thanks for the feeback we will look into this. As far as title and subtitle...these can already be controlled via an app variable. Hover over your chart and click the "Link" button and you will see this available under the General section.

As for the tooltip, you can customize it by returning an object from the custom formatter. Here is a blog post that goes over that.

In the next 6.3 update, we will add 1% to the max value of a line chart if a max value is not already set on the widget. For example, based on the chart you provided:
